Sea Point sees crime rate drop of two thirds after deployment of Hikvision cameras

Sea Point sees crime rate drop of two thirds after deployment of Hikvision cameras

Editor / Provider: Hikvision | Updated: 5/12/2015 | Article type: Infrastructure

Some of Cape Town's busiest roads, leading to one of the wealthiest suburbs, are now secured with an automated Licence Plate Recognition system installed by LPR Solutions. At its heart is a network of 42 sophisticated Day/Night cameras from Hikvision, whose iVMS video management software streams the video data to the LPR software. The increased surveillance has led to a dramatic drop in crime within the suburb, down an indicated 65% following the introduction of the cameras.

Sea Point is one of Cape Town's most affluent and highly developed suburbs, the only one in fact to have high-rise development of any significance. The area's oceanside location and general level of affluence make it very popular with city residents who enjoy the beach front promenade, a paved walkway along the beach-front used by residents and tourists for walking, jogging and socialising. It is also attracting a large amount of investment in second homes and apartments.

However, it is not that long ago that the area was regarded as less desirable, even dangerous. On top of South Africa's high crime rates, many of the apartment blocks had been neglected by absentee landlords, leaving them in poor physical condition. The result was a very high crime rate, much of which was attributed to vehicle-borne criminals.

Monitoring Universal Access
Located just a few kilometres west of the city's Central Business District, the roads that access Sea Point are some of the busiest in the entire peninsular. Many arterial roads lead in and out of the area, providing drivers with a wide variety of route options and appealing to residents and legitimate visitors. However, the sheer number of route options means that the criminal fraternity has also been able to enjoy only partially restricted access to this valuable real estate.

Recognising the potential to improve the safety and security of the area, the Sea Point City Improvement District, a joint Municipal/Police entity, decided to establish a licence plate recognition (LPR) system to monitor Sea Point's access roads and highways. Their aim was to identify and track every individual vehicle entering or leaving the area and co-ordinate law enforcement activity to combat crime. To design and implement the system they turned to local company, LPR Solutions.

Our challenge - the first LPR installation in Cape Town
"This project is the first large-scale LPR solution to be installed in Greater Cape Town," says LPR Solutions' Chris Hobbis.

"With an average of over 300,000 vehicle movements per hour being expected for the network of just over 40 cameras, the sheer intensity of traffic movement represented a considerable technical hurdle for the system designers to overcome. On top of this, the LPR system had to be robust enough to cope with the speed of the passing traffic on these major link roads in all weathers and be operational day-and-night.

"Therefore, our emphasis for the camera was on build quality, reliability, weather protection, image quality and true day/night capability," states Chris.

The LPR team also installed the network wireless and cabling links to feed the camera streams to a dedicated central control room located within Sea Point, which is manned around-the-clock by a staff of six.

The Solution
The focus of the design was to record every vehicle movement into and out of the Sea Point area from the minimum number of cameras. After analysing the road infrastructure, the engineers at LPR Solutions identified 42 points for the cameras, with each camera dedicated to monitoring one lane of traffic. Once these points were calculated, the demands to be placed on the cameras were investigated.

Although the primary imaging requirement was for a rugged and reliable, true Day/Night camera capable of withstanding the environmental conditions in this busy seafront neighbourhood, the team's stringent assessment protocol also included:

* Camera and video monitoring software features
* Product availability
* Level of technical support
* Price
* Total Cost of Ownership
* Warranty

Their eventual choice was the Hikvision DS-2CD4012F-A Smart IPC day/night box camera, with every camera protected from the environmental stresses by IP66 housing. Each camera's video stream is recorded on a dedicated server through Hikvision's iVMS video monitoring software suite and fed from there to LPR's itrack licence plate recognition software.

A truly SMART solution
Reflecting on their choice of the DS-2CD4012F-A camera, Chris says, "The main challenges we faced on this project were the changes in lighting conditions as we passed from day to the dark of night, the speed of the passing traffic and ensuring the utmost in reliability.

"We opted for one of the new breed of SMART cameras from Hikvision, which offers unparalleled image quality under all lighting conditions and fast, remote focusing capability whilst more than meeting our needs for efficient bandwidth and storage utilisation. Visitors to South Africa will know that daytime conditions can be very bright but the DS-2CD4012F-A copes with everything. Moreover, the bright lens produces brilliant 1280 x 1024 HD720p video at up to 60 fps, critical for an application where image detail is critically important. Combined with the Smart Focus capability, which allows the SMART cameras to automatically adjust the image sensor position to guarantee optimal focus without user intervention, accurate rendering of licence plates no matter what the vehicle speed has not been an issue.

"As well as Smart Focus, the Hikvision DS-2CD4012F-A also features a comprehensive suite of SMART features, including Smart Codec, Smart VQD (video quality detection), Smart Face Detection and Smart Audio Detection. The Smart Codec is particularly significant in a network situation as the advanced encoding algorithm streams images at a very low bitrate without compromising quality. Compared to traditional cameras, the Hikvision Smart cameras enhance image quality by up to 30% while minimizing the system's load and storage requirements. And, if necessary, up to 64 GB of on-board storage can be utilized," added Chris.

The result is crystal-clear images under the most challenging of environmental conditions, making it the ideal camera for all forms of surveillance, from large scale projects to small businesses.

A first for Cape Town and a Drop in Crime
The installation of Cape Town's first large-scale Licence Plate Recognition solution has had "an immediate impact", according to Chris. "Crime in the area has dropped dramatically! Early indications are that there has been a 65% decrease in recorded crime within the Sea Point suburb.

"Another immediate result of the success of the Sea Point installation is the award of a large, 75-camera contract from City of Cape Town Metro, which involved a change from the originally specified camera manufacturer to Hikvision Smart cameras.

"The roads in Sea Point are now being used by those with a legitimate interest in travelling to and from the area, and this is likely to have a significant impact on those that live, work and play within its confines. The contribution of the Hikvision cameras to this increased quality of life cannot be underestimated and should not be ignored."

University in Riyadh utilizes OT Systems' media converters

University in Riyadh utilizes OT Systems' media converters

Editor / Provider: OT Systems | Updated: 5/7/2015 | Article type: Education

Princess Nora Bint AbdulRahman University in Riyadh recently enhanced its billion dollar surveillance system by adding 150 pairs of OT Systems' ET1111 media converters to its state-of-the-art access control system spanning the entire campus. This is the University's second phase of OTS product installations. It first installed OTS solutions nearly four years ago as part of their video surveillance and perimeter-intrusion detection systems.

Princess Noura Bint AbdulRahman University, the kingdom's flagship security project featuring OT Systems' industrial Ethernet media converter, is the first women's university in Saudi Arabia as well as the largest women-only university in the world. In the campus, patrol patterns require more areas to be monitored by CCTV and access control systems when security guards are not present. The system utilizes a number of IP cameras installed along the fence and inside university buildings for perimeter protection and surveillance. Leveraging 986 pairs of OT Systems ET1111 (Industrial grade 10/100Base-TX + 100Base-FX media converter), each converter is dedicated to one IP camera or device. OT Systems guarantees the safety and stability of data transfer throughout the site using the point-to-point media converting solution. Only one camera will be affected if a converter is in trouble. Thanks to its extremely compact size design, the media converter is small enough to fit inside the IP camera housing. Its 24VAC power compatibility also shares a power source with the camera. Designed for outdoor installation, the ET1111 withstands operating temperature from -10oC to 60oC.

OT Systems' media converters offer customers a reliable and stable device for connecting IP devices with fiber links, providing an excellent transmission solution for the university access control system. It offers the flexibility of connecting the biometric readers at each access control location and the central server with a variety of fiber links (single-mode/ multi-mode, 1/2 core), extending the transmission distance up to 20km.

As security projects continue to increase in scale and complexity, system integrators face the issue of enhancing efficiency over longer distances. OT Systems' Ethernet media converter plays a key role in promoting a safe learning and working environment for its users.

You can't hide your heat: if it's a threat, it's hot!

You can't hide your heat: if it's a threat, it's hot!

Editor / Provider: Sponsored by FLIR | Updated: 5/6/2015 | Article type: Hot Topics

Security professionals have many different clubs in their professional bags. From cameras to ID badges, we have lots of things we can use to control access to the facilities we protect. As professionals, it is incumbent upon us to stay abreast of the latest technological developments in our field, and I'm here to tell you – there's a new game in town: thermal security cameras. Unlike the human eye, thermal imagers don't use visible-light to make a picture, they use heat. This gives thermal security cameras distinct advantages over low-light and daylight cameras when lighting is impractical, too expensive or where long-range performance is required. For years, thermal security cameras have been seen as too expensive, so we have made due with less expensive – and less capable – options, like night-vision devices and infrared illuminated cameras. Why? With high-quality thermal security cameras on the market for under $5,000, if we don't take a hard look at this technology we are selling ourselves, and those who pay us to keep them secure, short.

Why do I care? The short answer to this question is…range. And, in this business, range equals time: time to react, time to adjust, time to respond. Thermal security cameras detect the minute differences in heat that are all around us, all the time. This heat energy is easier to detect over longer ranges than visible light, giving thermal cameras a distinct advantage. In the picture to the right, the thermal cameras clearly show someone trying to break into a car (top), and a small boat (bottom). The corresponding infrared illuminated camera and the night-vision device might as well be looking at the inside of a cow. But that's not where the thermal advantage ends. Not only can thermal security cameras see from further away, they are not vulnerable to the most common countermeasure open to someone trying to avoid detection with a camera that depends on visible, or reflected, light: camouflage. Why? Simple: you can't hide your heat.

The infrared illuminated camera in this image was less than 50 feet from a person dressed in dark clothes on a moonless night and it came up empty. The same thing happens with the night-vision camera – nothing. But the thermal security camera picks out the intruder easily. Sure, you might say, but with the infrared illuminated camera you can identify your intruder better than with the thermal camera. True, but face it: if an intruder is so close to your infrared illuminated camera that you can identify him, you're going to be looking for a new job and he's probably eating at your snack bar. Use a thermal camera, and identify your intruder when he is in handcuffs. Thermal security cameras are useful in circumstances that relegate other camera technologies to fighting for second-place. Large facilities commonly have to deal with unfenced and unlit perimeter areas for economic reasons. Thermal cameras can see far enough to make this a non-issue, and they can do it for less money than it would take to install the infrastructure required for lowlight and infrared illuminated cameras.

How does it work? This may seem unbelievable, but really – this isn't rocket science; it comes down to some basic physics. We see reflected light. Infrared illuminated cameras, night-vision devices, and the human eye all work on the same basic principle: light energy hits something and bounces off it; a detector then receives it and turns it into an image. The ability a given detector – be it in an eyeball, or a camera – to create that image is directly related to the amount of light available. At night there isn't any sunlight to bounce off anything, so we're limited to starlight, moonlight and artificial lights. If there isn't enough, it's hard to see. Infrared illuminated cameras compensate for this by transmitting energy that bounces off whatever is in the camera's view and making a picture out of that. Unfortunately, severe range limitations result because reasonably powered illuminators are weak and the range performance of anything that relies on reflected light energy is limited by the strength of the energy being reflected. Why? Think about it – the energy squirted out of those little bitty illuminators has to go to the target and back before the camera can have a chance of detecting it. Unfortunately, those poor little photons just don't stand a chance past about 50 feet. By the time they get to the target, they've had enough and just scatter off into the ether. (Besides, if you installed illuminators strong enough to perform like a thermal camera you'd probably turn your plant into a big toaster oven.) Like your eye, infrared illuminated cameras work by detecting reflected light energy. Also like your eye, you will get better performance out of these cameras if the object you are looking for has lots of contrast compared to its background. If it doesn't, you won't see it. Know another word for that? Camouflage. That's right; camouflage is essentially just a way of decreasing the visible contrast between an object and its surroundings. Thermal security cameras suffer from none of these drawbacks. First, they have nothing to do with reflected light energy: they see the heat given off by everything under the sun (literally!). Everything you see in normal daily life creates heat energy – day and night, in good weather and bad. Just think: as you are sitting there reading this article, you are making a perfect thermal signature all by yourself. What's more the signatures of people, cars, buildings and all the other things seen by thermal security cameras generally have better contrast at night than during the day. They work just fine during the day – as long as there is the tiniest bit of temperature contrast between a target and its background, you can see it – but, they work great at night. And nighttime, as we know, is when the poop will most likely hit the paddles.


So, what have we learned today? We've learned that night-vision devices and infrared illuminated cameras have severe range limitations, and that this is a by-product of their reliance on reflected light energy. We've also seen that these cameras are at their worst when we need them most – at night! On the other hand, we've also seen that thermal security cameras create images from heat that is always there, that it produces its own contrast, and that they work best when we need them most.

Finally, and most important, we've learned there is only one word to describe a facility without thermal security cameras guarding its perimeter: target.

Crowd control: video analytics and alternative surveillance cameras

Crowd control: video analytics and alternative surveillance cameras

Editor / Provider: Israel Gogol, Freelancer, a&s International | Updated: 5/6/2015 | Article type: Hot Topics

Role of Video Analytics
The ‘classical' video analytics like detecting loitering and unattended baggage are not a good fit for a crowded scene. Masses of people standing and moving at one point near a race track and large numbers of bags in the scene will create too many alarms to make this solution practical.

Other analytics, such as face capturing and face recognition are also impractical in an outdoor event where there is no way to control the environment and make sure the cameras have a good view of people's faces.

“Video analytics tools are typically used for smaller crowds and are used in such instances as in prison yards, bars and other situations where there are a limited number of objects/people to be identified and analyzed. In such scenarios, the video and analytics are expecting to capture something specific – a certain face, a license plate image, a certain traffic pattern in the crowd or to see if a crowd is dispersing. Larger crowds/more objects make facial recognition ineffective because the faces are too small and/or occluded” explained Ian Westmaccot, Computer Engineering Manager, Tyco Security Products.

However, some video analytics can solve the need for detecting overcrowding and detecting aggressive behavior, like a fight that takes place in a crowded environment. Such an event might escalate and cause a stampede.

“In some instances you know that there is a very high likelihood of a crowd, such as in and around a football stadium on a match day. Other times you will have unexpected crowd build up, such a protest march, or disruption at an airport terminal. It is important to be able to plan for both eventualities” said Jamie Wilson, Security Marketing Manager for EMEA at NICE systems. “Video analytics is an important part of this process in being able to detect and flag early that there is an ‘unusual' congregation of people. Being able to display to the operator a live-feed of what is occurring and also the ability to roll-back and review what has triggered the incident is key to helping them to contain and control the situation” he added.

“Our new video analytics are now able to perform reliable detection and tracking under crowded urban environment. The system could perform real-time crowd size estimation; identify dominant patterns and statistics of the crowd, pick-up suspicious unknown and other hidden information” added Karianto Leman, Head, Situational Awareness Analytics Program, A*Star's Institute for Infocomm Research (I2R) in Singapore. Apart from crowd analytics, new video analytics are now able to very reliably detect suspicious human behavior such as violence, attacks, battering, breaking and entering etc. “I2R's aggression detection system had achieved beyond 90% accuracy in live trial at Singapore safe city project” stated Leman. Despite recent advances, video analytics are still very limited in a crowd-scenario. Crowd scenes are by nature detail-rich and this affects the reliability of video-analytics. According to Leman, a detection accuracy rate of 70% or more is a realistic expectation in this context.

Alternative surveillance cameras: Drones and Cell phones
Traditional pole-mounted cameras are still the most prevalent method of surveillance. However, other platforms have potential to become relevant in coming years. “Aerial surveillance using cameras on drones is gaining momentum in tandem with vast capability improvements and cost reduction of commercial drones” said Leman. “The challenge is in video transmission from drones to the ground. It could be costly over LTE and unreliable over WIFI. The solution is to enable edge computing on drone for video analytics. However, video analytics on video from drone is more challenging. It may require video stabilization and detection using different approaches from ground's video analytics” he explained.

Another potential camera, found in almost every pocket is the cell phone camera. “Mobile phones, in theory, have enough resolution to be useful in large crowd scenes. These mobile devices might play a larger role in surveillance once more cloud-based services become available and video management systems (VMS) are able to be used on mobile devices” added Steve Gorski, Chief Sales Officer at Scallop Imaging.


>>> Crowd control: securing outdoor events 

Crowd control: securing outdoor events

Crowd control: securing outdoor events

Editor / Provider: Israel Gogol, Freelancer, a&s International | Updated: 5/6/2015 | Article type: Hot Topics

On December 31, 2014, a terrible tragedy occurred in Shanghai, where around 300,000 people had gathered for the new-year celebrations on the Bund, a water front promenade which is part of Shanghai's historic downtown. Overcrowding on a staircase leading to an observation platform left thirty-six people dead and forty nine more injured.

This is only one sad example of the deadly force stored in crowded events. Human stampedes occur almost annually in music festivals, sports events religious festivals and night clubs. Famous examples are the July 2010, Love Parade music festival in Duisburg, Germany, where 21 people died from suffocation and at least 510 more were injured. In January 2006, over three hundred pilgrims died in Saudi Arabia as the result of overcrowding at the Jamarat Bridge, a pedestrian bridge that is part of the path believers walk through while performing the ritual Hajj pilgrimage to Mecca.

But what exactly is crowd control?
“We need to differentiate between crowd control that is done with access control tools, for example controlling a large number of spectators in a closed football stadium, and crowd control in an uncontrolled open environment like a street. The first one is achieved with conventional tools like security check points, turnstiles, gates and CCTV with video analytics based counters. The second one is usually closer to ‘safe city' projects and is more challenging and complicated since it is difficult to cover a wide area filled with people, be it for counting purposes or behavior analysis” explained Hagai Katz, Senior VP Business Development and Marketing at Magal Systems.

Accurate estimation of the number of attendees is indeed crucial for successful crowd control. Underestimating the number of people attending the Shanghai New Year's Eve was one of the factors leading to the tragic consequences. The police underestimated the number of attendees and assigned only about 700 officers (compared to 6000 officers in previous years) to handle a crowd that turned out to be 300,000 people.

In Germany, about 1 million revelers attended the Love parade venue that could only hold 250,000.

Role of video surveillance
In general, video surveillance cameras are still the main sensor for real-time crowd control and monitoring; “HD and IP network cameras have become the trend. 4K surveillance cameras have started to enter the market, but it is unlikely they will disrupt the surveillance segment. The cost of video transmission, storage, and processing (video analytics) would be prohibitive for 4K camera. Reliability would also be an issue” said Karianto Leman, Head, Situational Awareness Analytics Program, A*Star's Institute for Infocomm Research (I2R) in Singapore.

“For effective crowd control and monitoring, high-resolution video is critical to achieve situational awareness, as well as the ability to see greater detail within certain areas of interest. Today that means megapixel 180-degree cameras” stated Steve Gorski, Chief Sales Officer at Scallop Imaging. Scallop Imaging's cameras simultaneously combine output from multiple image sensors creating a continuous panoramic image that can cover a large outdoor scene. “We've seen a trend moving away from pan-tilt-zoom (PTZ) cameras because inevitably, when an incident occurs, it's likely that the PTZ camera is positioned somewhere else, and not able to see the action. Another reason for this trend is that the motor inside PTZ cameras tends to wear out over time” he added.

Portable solutions for Temporary Events
Unlike fixed venues, short term events like music festivals, sports competitions or city marathons pose a unique challenge for outdoor crowd control. The needed infrastructure is not always readily deployed and end-users face a dilemma of whether to make a big investment in infrastructure that will be used only for a few days.

A recent trending solution for such a scenario is the deployment of a temporary surveillance system using a wireless mesh network, which is easy to establish and then take down during an incident or public event. Because it doesn't require a fixed infrastructure, a mesh network is commonly deployed by public safety departments, municipalities and police forces. “The network is usually made up of mesh network software, digital cameras, workstations, a server and mesh nodes (hardware) that share information with one another wirelessly. Radios, smart devices or mobile devices of some kind often provide communication pathways between operators. Video analytics and other technologies can then be deployed in these temporary systems” detailed Ian Westmacott, Computer Engineering Manager, Tyco Security Products .

San-Diego based MicroPower Technologies offers a solar powered wireless system that allows deployment on a per-need basis.

“Flexibility is key. Utilizing an integrated solar/wireless surveillance system as an extension of the broader surveillance system allows users to deploy and redeploy the cameras as their needs evolve” explained Dave Tynan, Vice President of Global Marketing and Sales, MicroPower Technologies. “We're seeing growing interest in technology that can be quickly and easily installed directly at the points where it is needed most. Rather than, for example, installing fixed cameras on a building and then attempting to gain usable footage of a crowded event several blocks away, customers want to be able to place cameras closer to the hot spots of risk. This is particularly true for night activity, when placing cameras closer to the action helps take advantage of available light. The result is clearer, more usable video evidence” he added.

The benefit of this solution is the ability to deploy cameras according to immediate needs, e.g. at a parking lot during a major event, and then re-deploy them to other hot spots in the next big event without running costly and time consuming cables.

However, an important factor that needs to be taken into account is the limited transmission range that wireless cameras have and the image quality which is not Megapixel. This type of portable solution is suitable for securing a defined ‘hotspot' but might not be as relevant when securing the long route of a marathon.

Portable solutions are not just for video surveillance. temporary fences and even vehicle barriers are available. “Parking for temporary events like football games, political meetings, freshman matriculation day and open houses requires only a temporary solution. Our solution is in the form of portable, towable barriers. These barriers can be deployed quickly and effectively, even in places where it's impossible to excavate for a permanent foundation,” said Greg Hamm, Vice President, Sales & Marketing, Delta Scientific. “These mobile crash barriers can be towed into position by a medium-sized pick-up truck or equivalent. They deploy in 15 minutes and can be operated locally or remotely for guard protection. Deployment, retrieval and operation are all hydraulic. The barriers stop and disable a 15,000-pound vehicle (6803 kg) moving at 30 mph (48 kph). Once positioned, the mobile barricade is separated from its transporter and lowered into position by means of a battery-operated hydraulic power system, which is then used to raise or lower the barrier for normal or emergency tasks”, described Hamm.

Information transmission
Another challenge outdoor events pose is how to transmit high quality video streams from the cameras to a remote security center reliably and in a cost efficient way for processing, storage and viewing. There are several option including transmitting the information over cable, over a dedicated wireless networks, or using 3G/LTE networks. “In the latter configuration, cameras will compete in bandwidth with civilian cell phones that use the same network” explained Leman, “The solution is to reduce the requirement to transmit video all the time. This can be done with an edge computing device that runs video analytics. The device stores video locally and will only stream back video when a video analytics alarm is triggered” he added.

Wireless networking for surveillance solves the need for cables, which might not always be optional or easy to install (either due to specific area considerations or due to cost if it is a temporary event). However, this type of networking is more difficult than wired networking: having to overcome difficulties such as, limited range, obstructions (houses, trees etc.) and complicated configurations when many cameras are involved. NVT's IP transmission product technology allows for the deployment and PoE powering of cameras, event monitors and other IP sensor devices deployed at great distances using very cost effective coax cable.

“In the case of the recent NY City Marathon, NVT supplied coax connected transmission devices that needed to be fully operational at distances of up to 3,000ft in order to provide effective situational awareness for the securing of this large event” described Guy Apple Vice President, Marketing and Sales Network Video Technologies.

Physicists are trying to understand the dynamics of crowds. Their analysis of video footage from events like the Saudi Arabian pilgrims stampede and the German Love Parade helped identify the phenomenon termed “crowd turbulence” – as the scene becomes more and more crowded, more and more people push forward trying to move. The overall pressure of the masses moves through the crowd causing people to fall and eventually to be crushed to death. Hopefully, advances in video surveillance and video analytics will give better ways to count people and identify the ‘tipping-point' beyond which a crowded event has the potential to become deadly.

Secutech Excellence Award sheds light on 4K Technology

Editor / Provider: Sponsored by Secutech | Updated: 4/29/2015 | Article type: Hot Topics

Boasting resolution of 4,096 x 2,160p (around four times that of hull HD resolution), 4K has the ability to display UHD (ultra high definition) video footage. The ability to capture a large scene and zoom in on images without sacrificing pixels makes 4K ideal for monitoring large areas, which is useful for city surveillance and transportation applications. Additionally, as one 4K camera can substitute many HD cameras, it presents as a cost-effective solution which also minimizes blind spots. With 4K technology, data collected from video recordings creates opportunities for improved investigations, but also business intelligence.

Having focused on HD technology, the 5th edition of Secutech Excellence Award will keep up with the pace by presenting the best brands of UHD IP cameras, panorama IP cameras, and NVRs. Participating brands include Brickcom, Dahua, Honeywell, LILIN, Panasonic, QNAP, Synology and VIVOTEK. Buyers will be able to witness demonstrations and vote for the winners at Booth 8501. The award ceremony is scheduled to take place at 11:00 AM on 30 April.

EtherWAN, the sponsor of Secutech Excellence Award, has pointed out that whether a network surveillance system operates properly depends on the signal transmission between monitors and cameras, and the complete integration of storage and VMS, which is a challenge that every system integrators must face with. Modern network cameras utilize PoE technology to support both power and data transmission. In this expo, EtherWAN Systems will showcase the latest Ethernet connectivity products; and will also share the valuable experiences from network planning to versatile success stories in both local and overseas installations.

What kinds of projects need ccHDtv only?

What kinds of projects need ccHDtv only?

Editor / Provider: Jill Lai, a&s International | Updated: 4/17/2015 | Article type: Hot Topics

ccHDtv can be the only solution in some special occasions. For example, “If you want to have over 16 daisy-chain surveillance cameras on one coaxial cable, ccHDtv is the only solution. If you have a coaxial cable that is over 1,000-meters long in your installation site and you wish to use it to carry multiple full HD video, with 1080p at 30 frames per second, ccHDtv is the only solution. If your installation has room for only one coaxial cable but you want video, audio, control, and power simultaneously, ccHDtv is the only solution. If you have very poor cabling but you still want crystal clear HD video, ccHDtv is the only solution,” H.Y. Lin, President of ITE Technologies emphasized.


Current ccHDtv Projects at a Glance

1. A molding factory in China uses 16 ccHDtv cameras with the requirement for a transmission distance over 250 meters. The ccHDtv system provides better image quality, compared to IP video surveillance, with long-distance transmission.

Unifying ccHDtv Suppliers Through an Alliance
With ccHDtv technologies and products getting more mature, ITE is also able to include more partners and suppliers of ccHDtv products. The company, then, established the ccHDtv Alliance this January to consolidate its marketing and sales strategies. ccHDtv standards and specifications were first announced to the market in Nov. 2012. Now, the company has over 10 qualified Taiwanese manufacturers that have adopted these specifications to develop their individual product series. “ITE provides allied companies with full support and services, including tests, certificates, and system integration, to help them manufacture a next-generation HD digital surveillance system with high quality and efficiency,” said Lin. Through the alliance, ITE hopes to bring ccHDtv to another new level, by collaborating and consolidating the resources from all the members, especially when exploring international markets.

ccHDtv now is still in the early technology introduction phase of its product life cycle. It needs more partnerships from security suppliers and recognition from global systems integrators in order to expand its market shares. ccHDtv provides systems integrators another option when implementing a video surveillance project, which is especially beneficial for both sales channels and end users alike. With this, we hope to see a significant growth for ccHDtv in the near future.




What makes ccHDtv unique is its “transmission technology,” according to Lin. Based on DTV technology, ccHDtv uses COFDM and radio frequency (RF) transmission technologies, which bring many benefits to the whole system, such as high noise resistance and bandwidth. He further explained that current IP video surveillance system use TCP/IP transmission technologies to transmit digital signals over Ethernet cables. Therefore, an IP video surveillance system usually has image latency problems. It goes without saying that these problems might get worse when transmitting 4K video. However, ccHDtv is different from IP because of the COFDM and RF transmission technologies...... Read On

Sony's 4K security camera embedded with 1.0 type Exmor R CMOS sensor for advanced imaging

Sony's 4K security camera embedded with 1.0 type Exmor R CMOS sensor for advanced imaging

Editor / Provider: SONY | Updated: 4/13/2015 | Article type: Hot Topics

Sony is adding 4K imaging to its line of security technologies, with the new SNC-VM772R camera. The new model combines the enhanced resolution of 4K with low-light sensitivity leveraging 1.0 type back Illuminated Exmor R CMOS image sensor, bandwidth optimization features, and intelligent scene capture capability to adopt the best picture quality, ideal for city surveillance, transportation, railway, traffic monitoring and airport surveillance applications.

4K technology gives security users the ability to capture content at four times the resolution of Full HD (1080p). With the exceptional detail provided by 4K technology, security professionals can expand their wide area surveillance and still capture, magnify and examine the smallest parts of a scene like a face or a car license plate number – all with a single camera. TheSNC-VM772R camera combines these benefits with enhanced visibility, reduced total system costs and flexible and easy installation.

"4K is the new video security standard," said Katsunori Yamanouchi, Vice President, Sony Professional Solutions Europe. "But 4K imaging is about more than just increased resolution. It's also expanding the application potential of security cameras and helping to transform security and surveillance. The increased resolution covers a larger area, improving situational awareness and ensuring nothing is missed. These benefits help security professionals reduce installation and operating costs as fewer cameras are needed for specific areas."

The introduction of the SNC-VM772R to the security industry extends Sony's 4K leadership in the broadcast and production industries, where Sony's 4K cameras are shooting blockbuster movies, popular television shows and major sporting events. Sony's 4K digital cinema projectors are in movie theaters worldwide and Sony's 4K TVs bring content to consumers.

Sony has developed several unique technologies to overcome the challenges of 4K cameras in the market: improving visibility and light sensitivity while reducing the amount of bandwidth needed to handle large 4K files.

Low-light Sensitivity
Higher-resolution imaging has traditionally come at the expense of low-light sensitivity. The new SNC-VM772R uses a 1.0 type 20MP Exmor R sensor and is capable of 0.1 lx sensitivity for clear image capture in light and dark conditions.

A back-lit structure doubles the camera's light sensitivity and a built-in infrared (IR) light source which enhances low-light use and nighttime shooting with visibility at longer distances.

In wide area coverage, various lighting conditions exist during the day and night. SNC-VM772R also has 90dB wide dynamic range and 30fps to deliver clear, sharp images for better visibility and recognition.

Finally, a 2.9-times motorized zoom lens is matched to the image sensor to maximize video resolution. The lens features optical image stabilization and helps capture images with low distortion.

Flexible settings and optimized streaming
The new camera uses Sony's unique bandwidth optimization technologies so users can customize streaming settings and the camera's operation.

An Intelligent Coding feature reduces storage and bandwidth consumption by adopting different compression depending on the area of interest. Intelligent Cropping and Multi-Tracking show an overview of an area and allows for “region of interest” selection of up to a maximum four areas at a time, so users can select only the portion of an image they want to see in 4K resolution, while also streaming a scaled full HD image. This results in 50 percent less bandwidth consumption by reducing the amount of video transmitted in 4K resolution, and makes wide area monitoring more effective and targeted.

Intelligent Cropping has two patterns for selecting the size and number of areas, and also employs two modes: Static, to view multiple fixed areas in one scene; and Dynamic, to detect moving objects.

Evidence Shot lets users see critical moments in the camera's highest resolution of 20MP in still shot mode, which is 2.4 times more pixel resolution of 4K. Alarms can be sent with Video Motion Detection for specified scenes.

Wide selections for setting best images
The Intelligent Scene Capture function automatically adjusts and adapts picture quality (brightness and color) depending on time, weather and lighting conditions. The SNC-VM772R camera also allows users to customize picture parameter presets for the best settings between day/night and multiple picture configurations can be saved and switched either manually (using the Picture Profile mode) or according to schedule (Picture Profile Scheduler).

The new SNC-VM772R is planned to be available in the third quarter of 2015. It will be supported by major VMS providers, including AxxonSoft, Exacq Technologies, Genetec Inc., Genius Vision Digital Inc., Lenel Systems International, Inc., Milestone Systems, NICE Systems, NUUO Inc., On-Net Surveillance Systems, Inc., SeeTec AG and Verint Systems Inc.
