HD-over-coaxial: Ultimate battle for survival by analog manufacturers

HD-over-coaxial: Ultimate battle for survival by analog manufacturers

Editor / Provider: Alf Chang, a&s International | Updated: 10/23/2014 | Article type: Tech Corner

The overarching view in the security industry right now is that IP, which employs a network infrastructure and offers HD video, will one day replace analog solutions, which have defined video surveillance for half a century. For analog players, who are seeing declines in sales and revenue, they must find ways to regain their former dominance in the industry. HD-overcoaxial solutions, which deliver HD video over users' existing coaxial cabling, represent their ultimate battle for survival amidst the IP invasion.

Ever since 960H and HD-SDI emerged in 2011, video surveillance players have been trying to find solutions that enhance the quality of CCTV, which remains the mainstream surveillance technology. Analog cameras are inexpensive and easy to install, and they still dominate the market with 70 to 80 percent of market share. However, IP cameras are threatening the very existence of analog players, who are seeing a steady revenue decline. Against this backdrop, analog players seeking to survive have put intensive efforts into the R&D of high-resolution HD-over-coaxial solutions. HDCVI, HDTVI, ccHDtv, and AHD are the products of those efforts.

Any HD-over-coaxial solution, be it 960H, HD-SDI, HDCVI, HDTVI, AHD, and ccHDtv, must be easy to use over the end user's legacy coaxial cable. HD transmission should be achieved using 5C-2V (RG-59U) or 3C-2V (RG-6) coaxial cable without quality loss, and the traditional distance barrier of 100 to 200 meters must be overcome. The solution must incur no extra cost for installation or upgrade, resist quality loss over a long distance, and enable easy upgrade to megapixel-level HD surveillance. Further, it must be high in quality and competitive in price to gain a stronger foothold in vertical markets. In summary, for a solution to be called HD-over-coaxial, six basic requirements must be met:

1. It must have high video clarity and color separation, as well as high signal filtering, noise reduction, and image restoration capabilities;

2 .As HD-over-coax is claimed as a breakthrough technology, it must be able to transmit signals for a longer distance over existing coaxial cable;

3 .The solution must not be subject to latency, compression-related quality loss, or any compromise to video quality;

4 The backend equipment must be compatible with the 960H format, and future compatibility with analog splitters and matrix systems must be considered;

5. HD-over-coax must be easy to use and operate and allow settings on both frontend and backend equipment;

6. Any solution must have low cost and high quality.

There are HD-over-coaxial DVRs that can support both 960H and 720/1080p. These are called hybrid HD DVRs. There are even HD DVRs that are bolstered by Intersil's decoder chip and the TCP/IP interface to support 960H, 720p/1080p, and IP signals. These are called Tri-brid HD DVRs.

Compare and contrast between solutions
HDCVI, HDTVI, and AHD share one thing in common: as opposed to 960H that uses the CCD sensor, HDCVI, HDTVI, and AHD use the megapixel-level CMOS or Exmor CMOS sensor. The purpose is to capture HD images at the source level. Among manufacturers of CMOS sensors are Sony, Omnivision, Pixelplus, and BYD. The formation of images differs slightly according to brand.

Another similarity as far as components are concerned is the use of an image signal processor (ISP) in conjunction with the sensor. This device ultimately determines the final image displayed by HDCVI, HDTVI, and AHD solutions. The chipset could be integrated into the sensor module or into the transceiver at the backend of the HDCVI, HDTVI, or AHD camera. Image signal processors, whose manufacturers include Sony, Fullhan, Nextchip, and Eyenix, process and enhance images formed by the sensor. As ISPs of different companies are designed differently, they have different ways of handling backlight compensation, WDR noise reduction, and the 3As, namely auto white balance, auto exposure, and auto focus.

One final thing that the solutions have in common is the presence of a signal transceiver, which produces different signal formats based on the technology in question, namely HDCVI, HDTVI, and AHD. Regardless of the technology, these transceivers are similar in that they combine signal augmentation, voltage augmentation, and MCU all in one device and emit signals over different transmission distances. There is also a circuit switch that allows cameras to switch between HD-over-coaxial and CVBS output.

All HD-over-coaxial signals travel through coaxial cables, which can be 5C-2V (RG-59U) or 3C-2V (RG-6) for transmission of between 300 and 500 meters. Among the things that set them apart are the codec engine, which is made by TI, Hisilicon, or Grain Media, and the performance of ISP processing.

Application in verticals
Based on how things look right now, to popularize HDCVI, HDTVI, and AHD and widen their reach in different verticals, it seems manufacturers still have lots of publicity and marketing to do. In fact, I still have doubts over their market acceptance beyond the banking, financial, and retail verticals, as 960H and HD-SDI themselves are still mostly deployed in retail, banking, and education. It is my hope that fiber optic providers can develop and commercialize HD-over-coaxial interfaces, so that HDCVI, HDTVI, and AHD can go beyond small and medium implementations and find their way into city and highway surveillance, which requires HD and real-time video transmission.

Currently, there aren't any credible or authoritative figures on the market acceptance toward HDCVI, HDTVI and AHD. Yet, marketing strategies differ according to manufacturers and their OEM partners. Based on our observation, a lack of understanding of the different solutions is the biggest obstacle that manufacturers need to deal with right now.

Opportunities and future development
HD and intelligence are future development trends that analog players seeking to upgrade their HD products future, advances in CMOS, ISP, and transceivers will cause HD-over-coaxial surveillance to become a norm. Applications in different verticals will also become more noticeable. In security, there is a notion that IP will replace analog. But this will not happen anytime soon, and HD-over-coaxial marks the effort by analog players to at least slow the IP invasion and analog's decline. In the end, maybe there is a purpose for the existence of these solutions.

Crawley & Horsham Hospital increase security level with Nedap AEOS

Crawley & Horsham Hospital increase security level with Nedap AEOS

Editor / Provider: Nedap | Updated: 10/14/2014 | Article type: Commercial Markets

Crawley & Horsham Hospital has explored new technological possibilities to increase their security level in an effective manner. They have chosen the security management platform Nedap AEOS.

 

 

 


Project overview
A hospital works 24 hours a day, 7 days a week, non–stop, and security needs to be guaranteed for the access of different people that use the hospital (patients, doctors, nurses, visitors, etc.). It is therefore very important to control lockdown. In response to NHSLA requirements to undertake a risk profile of lockdown procedures, Nedap was invited to visit Crawley & Horsham Hospital in Crawley, West Sussex. The hospitals security team wished to explore new technologies available to enable them to adhere to the new directives in an easier and more effective manner.

Definition
When security of patients, staff or assets is at risk by any identified threat or hazard, a lockdown should be achieved. Lockdown is the process of controlling the movement and access of people, including staff, patients and visitors within a specific building or area. Entry, exit and movements of people within an NHS site can be controlled by both security employees and physical security measures.

Implementation
The ability to enable the hospital to follow the NHSLA lockdown directives was the main goal. But the security team was keen to explore their future options to gain the most out of any new investment. Therefore they opted for a flexible solution that offered the possibility to integrate new technologies at any time and that could be managed centrally with other disciplines of security.

Initially the scope was to secure all doors that covered the main access areas within the hospital. Due to the flexibility and feature rich benefits of Nedap's AEOS security management platform, the trust security team decided to transfer total control of security management to AEOS. Nedap also offers products available through additional license purchase or integration options; such as vehicle and car park security, secure lockers and medicine cabinets and CCTV management.

About Crawley & Horsham Hospital
Built in the 1960‘s, Crawley Hospital enjoys a near town centre location. Originally Crawley District General Hospital, Crawley merged with Horsham Hospital in the early nineties to form the Crawley Horsham NHS Trust, one of the first Trusts to be established. Crawley and Horsham Trust joined with East Surrey Healthcare NHS Trust in 1998, creating Surrey and Sussex Healthcare NHS Trust.

ccHDtv is the answer to a facile surveillance system upgrades

ccHDtv is the answer to a facile surveillance system upgrades

Editor / Provider: Sponsored by ITE | Updated: 10/6/2014 | Article type: Hot Topics

As school shooting incidents have been soaring in recent years, school administrators are paying more attention to campus security system upgrades. Among all the solutions, upgrading out-dated analog CCTV surveillance systems to more e¬ffective high resolution surveillance has been a priority.

HD-SDI was the only megapixel surveillance solution that utilized traditional analog coaxial cabling infrastructure, until ccHDtv was introduced to the security market. Since the introduction of megapixel IP cameras to the security market, coaxial cable was considered too outdated to support such high quality images. Therefore, customers spent a lot of money to have their analog infrastructure taken out and replaced with network cable, this work often requiring a significant investment of time and resources.

One of the drawbacks for HD-SDI and IP systems was the cable-run distance limitation, as these technologies cannot exceed cable lengths of 100 meters. Considering that analog CCTV cables can be installed on longer distances of cabling, this caused problems and extra costs for many school campuses that required cameras to be installed further away.

Stardot Technologies, one of the leading manufacturers of IP, ccHDtv cameras and video encoders in the United States, has successfully provided ccHDtv cameras allowed a school surveillance system to be upgraded and without replacing the existing coaxial cables. This upgrade was performed in the administration building of Alta Loma School District in California, U.S., in Dec, 2013. In this project 12 SDHM200BN Day/Night ccHDtv cameras and 3 SDHMSRV4 ccHDtv channel receivers were deployed along with a 16-CH ExacqVision NVR.

The school administrators at Alto Loma School District believe that ccHDtv was the right choice once they had considered the cost and resources required for upgrading surveillance system and installing new cabling. Using ccHDtv cameras allowed the school district to upgrade their surveillance system without having to spend a significant amount of their annual budget. Alto Loma School District now has a high quality surveillance system with more effective megapixel cameras. The school district is planning on installing ccHDtv throughout the other eight elementary schools and junior high schools in the Alto Loma School District in the coming years.

Editor / Provider: AMG | Updated: 9/17/2014 | Article type: Security 50

AMG, the British manufacturer of CCTV transmission solutions and sophisticated 5 Megapixel cameras, has completed a new sophisticated toll management transmission solution on Solapur Highway, for ITNL in India. ITNL is using the solution to monitor two Toll Plazas with a total of 20 Lanes with 24 Booths – 4 of which have reversible lanes. The project covers a road stretch of 105 kilometres, with 49 kilometres between the Toll Plazas.

According to ITNL, the new system encompasses 132 cameras of which 126 are fixed cameras and 6 are PTZs. Other hardware integrated into the solution includes Lane Controllers, AVC Controllers, and RFID Readers. The system is operated on an Ethernet backbone, with 35 unmanaged AMG switches, and incorporates vehicle detection and enforcement solutions along with access control equipment.

A Toll Plaza typically lies in an environment where adverse conditions are present. This was a decisive factor in ITNL's decision to select the AMG Ethernet switches for the new system. The ruggedness and small form factor, as well as the capability to perform well in adverse climate conditions with extreme heat and dust means that the AMG switches provides significant advantage over other alternatives.

According to ITNL, another advantage is that the AMG transmission solution can interface with equipment from any given third party manufacturer. This facilitates the integration of surveillance and monitoring equipment with the Toll Management Solution. ITNL also commented on the support given by AMG during pre-sales, post-sales and subsequent technical support, deeming the service as ‘excellent'.

Hikvision ensures Fun Safe Philly Summer in Philadelphia

Hikvision ensures Fun Safe Philly Summer in Philadelphia

Editor / Provider: Hikvision | Updated: 9/12/2014 | Article type: Government & Public Services

Hikvision teamed up with the City of Philadelphia to ensure success of their “Fun Safe Philly Summer” initiative. The program connects youth and their families to free and low-cost summer activities, including many events at the recreation centers spread throughout the city. With the safety of the community in mind, the city council has pledged significant budget investment to outfit all 140 centers with CCTV by 2016. After careful evaluation of all the products on the market, Hikvision's high-performance cameras, NVRs, and VMS technology were selected as a cost-effective solution to protect the city with cutting-edge video surveillance.

With over 600 facilities serving thousands of people each year, the Department of Parks and Recreation worked closely with City of Philadelphia Engineer Pedro Pinto to develop a high standard for CCTV design criteria. A primary concern was finding a system that could stay intact as existing infrastructure was gradually upgraded throughout the city.

“The system needed to be scalable and had to be networked at some point in the future,” explained Sheeba Money, Special Systems Designer at Arora Engineers, Inc., a firm involved with CCTV design for the City of Philadelphia. “With every department of the city operating on a different system, it was crucial to provide a video surveillance solution in the rec centers that could be linked into a central management system.” Because Hikvison's Video Management Systems easily communicate with each other and with systems made by other manufacturers, the feature-rich, reliable, VMS 4200 was the choice.

The video surveillance systems have been hugely successful in keeping the centers safe. In most cases, the presence of the cameras alone has been enough to prevent crime. Susan Slawson, Deputy Commissioner of Parks and Recreation, noted: “Where we were faced with vandalism, loitering, and burglaries before, the numbers decreased immediately once we outfitted our facilities with cameras. We don't just want a ‘fun, safe, Philly summer;' we want a fun, safe, Philly. With introduction of Hikvision video surveillance equipment, not only are we covering our sites, we can tell what's going on in the streets and coordinate with the police department if need be,” Commissioner Slawson, herself a 20-year veteran of the Philadelphia Police Department, affirmed. Superior image quality from the Hikvision cameras plays a key role. “We have good video,” Police Commissioner Charles Ramsey confirmed, “that should help us a great deal.”

Fidelity Alarm installed the DS-2CD7254FWD-E 3MP Outdoor Network Camera in several of the rec centers due to the camera's wide dynamic range and true day/night functionality. “In addition to gathering footage from the immediate vicinity, it captures clear images from as far away as across the street,” explained Pat Phillips, Sales Manager at Fidelity Alarm. This month's shooting at the Dell Music Center is a tragic example of criminal activity dealing a blow to the community, but the police had a head start on the investigation due to cameras stationed on the building's exterior by Fidelity Alarm. Footage was provided to the police and images were released to the public so that the perpetrators could be swiftly identified.

Jeffrey He, president of Hikvision USA, remarked, “Hikvision is proud to provide versatile, convenient, and efficient video surveillance solutions to the City of Philadelphia. Hikvision technology protects our society's most invaluable asset – our young people – in municipalities across the U.S. and Canada. As we continue to rapidly expand, we look forward to bringing even more success stories to the North American market.”

FLIR helps stop and prevent stealing attempts in Namibia diamond mines

FLIR helps stop and prevent stealing attempts in Namibia diamond mines

Editor / Provider: Sponsored by FLIR | Updated: 9/23/2014 | Article type: Commercial Markets

Oranjemund, situated in the far south western corner of Namibia, means mouth of the Orange River. Accessing the town is impossible without a special permit issued by the Namibian Ministry of Mines and Energy. In Oranjemund, diamond theft is a serious concern as it is one of the richest diamond fields in the world. A big sign saying, “Diamond theft hurts us all – Don't do it”, is one of the first things visitors see when they arrive at the local airport.

Stealings planed by criminal groups
Diamonds are very small and easy to conceal. Therefore making sure that as little as possible diamonds are being stolen is of the utmost concern to all mining companies. Even to the company which holds multiple mining licenses in Oranjemund, diamond theft is a serious issue.

While the mines are very rich and produce stones of the highest quality, most of the product is gem stone quality, used for jewellery, with only a very small percentage of industrial stones. Workers working on the bedrock, the bottom layer where the diamonds are situated, regularly spot diamonds with the naked eye. If a worker picks up a diamond and hands it over, the experts will determine the value of the stone and 70% of its value is given to the honest finder. This way we try to discourage theft. Nowhere else can a worker gain this amount of money for a precious stone.
The problem is that workers are sometimes under pressure from criminal organizations to steal diamonds. Still numerous people are trying to steal the diamonds. Though at the “black market” they will only receive a small amount of the stone's value. Although strict security measurements are in place, they still try to steal using different methods.

Strict security deployment
The bedrock area is a critical area to guard when it comes to fighting against diamond thieves. Movable wireless camera systems called “spider cameras” on the bedrock mining sites are introduced for monitoring workers closely. These are small, movable CCTV cameras installed on the bedrock, close to the workers.

Thermal imaging cams detect stealing in the dark
For workers with stealing plans, they become aware of being monitored. Therefore the thieves hide stones in a remote area of the bedrock area. During the night, the thieves come back to collect the diamonds. On active bedrock sites, FLIR Systems SR-100 thermal imaging camera has been deployed in real cases. There is not supposed to be any activity on the bedrock sites during night time. If anyone tries to access at night to pick up diamonds, the suspects can be seen immediately on monitors. The pan/tilt function can effectively track the target to help security patrol on the way arresting the suspects.

Customized housing enhance image quality against harsh conditions
The cameras operating on the bedrock areas are operating in extremely harsh conditions. Close to the sea, they are susceptible to salt spray, and exposed to strong winds. To customize the solution, , FLIR have constructed a “Stainless Steel 316” housing although the cameras are extremely well protected. The FLIR Systems SR-100 cameras are installed in the housing together with a CCTV camera which overlooks the bedrock during daytime. The housing containing the two cameras is installed on a pan/tilt which increases situational awareness and allows following people when necessary. ”

Guarding all essential areas
Entrance, exit and no-mans land secured

The essential areas for security include not just the bedrocks, but also the entrance and exit to the mining areas. They are all secured and monitored with thermal imaging cameras. However, between the mining area and the town exists a “no-mans land”.
In a real case, security people monitor the entrance and exit to the Mining Area and the “no-mans land” with other equipment in place, and continuously with a FLIR Systems PTZ-35x140 MS thermal imaging camera. During daytime, the daylight camera installed in the PTZ-35x140 MS operates; when it gets dark, it is switched to the thermal cam. The PTZ-35x140 MS, perfect for security needs, can zoom in and catch closer look at suspect's activities.

Tricky stealing attempts stopped
One of the ways that people try to get diamonds out of the mining area is by shooting crossbow arrows over the “no-mans land”! The arrows are hollow and the inside is filled with diamonds. According to local security professionals, an accomplice picks up the arrows on the other side. Thanks to the PTZ-35x140 MS, we can now monitor, in total darkness and also in foggy conditions, what is happening alongside the fence. If we see people approaching and suspect illegal activity we send out a patrol. Since the PTZ-35x140 MS is mounted on a robust pan/ tilt mechanism, we can overlook an entire area and if necessary follow a suspect person so that he can not get away.”



Excellent value created

To the local mining companies, they reckon they get excellent value for their money paid. The FLIR Systems cameras contain a Vanadium Oxide detector, producing excellent images, revealing the smallest of details. These images are produced with a frame rate of 9 Hz, saving the clients any export license to install them in Namibia. However, they save more. Compared to other cameras that have been installed, which contain a BST detector. In order to operate well, they needed an internal mechanical chopper that calibrates the image. This chopper was very susceptible to breakdowns. With FLIR Systems material, the clients are no longer bothered by these problems. They get excellent value for the money paid.

With real deployment in Oranjemund , thermal imaging cameras have proven their worth here. Advantages of thermal imaging compared to traditional fences and cameras are clear. Given these success stories in local mining areas, more projects are being considered.
