Samsung Techwin video surveillance solution for Sisli Municipality

Samsung Techwin video surveillance solution for Sisli Municipality

Editor / Provider: Samsung Techwin | Updated: 11/18/2014 | Article type: Government & Public Services

Samsung Techwin has been entrusted to provide an end-to-end IP network based video surveillance system to help create a secure and safe environment for all who work in, or visit, the Sisli Municipality's new administrative offices.

Images captured by 170 Samsung Techwin cameras installed within the offices and surrounding areas are monitored in a central control room where they can be viewed live on Samsung Techwin monitors, whilst being recorded onto network video recorders.

Sisli is one of the major 32 districts of Istanbul on the European side of the city. Covering an area of approximately 30 square kilometres, it is located at the exit of the Bosphorus Bridge that links Asia to Europe. It is one of the busiest areas of Istanbul with a thriving business community and is popular for its fashion stores.

Moving to a new international award winning building provided Sisli Municipality with the opportunity to introduce smart building technologies to provide an efficient and environmentally friendly workplace for the district's administrators. The Municipality's leaders wished to see a video surveillance system installed that could similarly be regarded as ‘smart'.

The contract to install the IP network video surveillance system was awarded to Istanbul based CCTV specialists, Melis Elektronik, who successfully completed the entire project within three weeks.

Melis Elektronik worked closely with Samsung Techwin's distribution partner in Turkey, NFS Teknoloji, to design a system that could assist security personnel to monitor any suspicious activity and quickly decide on an appropriate response.

“Having carried out a survey of the district and understood what the Sisli Municipality wanted to achieve, we had no hesitation in recommending to Melis Elektronik that we should supply a single source solution from Samsung Techwin that, from a technology point of view, could easily meet the clients' expectations,” said Mrs Handan Anar, Deputy General Manager for NFS Teknoloji. “Equally important, although Sisli Municipality wanted to take advantage of the very latest IP technology and did not want to compromise on image quality, there was not an unlimited budget for the project. Samsung Techwin's competitively priced cameras, monitors and recorders were therefore an obvious cost-effective choice.”

77 of the cameras installed are Samsung Techwin SND-6083P 2MP dome cameras with varifocal lens and 68 are SNV-6084R 2MP vandal resistant dome cameras.

“These cameras were chosen partly because of the superb quality images which they are capable of capturing, but also because they are future-proof in that they are equipped with Samsung Techwin's open platform WiseNetIII DSP chipset,” said Mrs Anar. “The processing power of this chipset offers Sisli Municipality the opportunity to take advantage of the fact that the cameras can run multiple Applications if it wishes at anytime in the future such as video analytics, facial recognition, people counting and ANPR which can be downloaded to the cameras in a similar way to adding Apps to a Smartphone.”

17 of the other cameras installed are Samsung Techwin SNO-7080R 3 megapixel weatherproof network bullet cameras with built-in motorised varifocal lens and IR LEDs. The SNO-7080R is capable of capturing evidence grade Full HD 1080P resolution images at 30 images per second, both during daylight hours and in pitch-black darkness, making it suitable for a wide range of applications requiring effective 24-hour surveillance.

The images from all the cameras are recorded on 4 SRN-4000 network video recorders enabling authorised personnel to quickly retrieve recorded video evidence of any suspicious activity. The SRN-4000 is able to simultaneously record and multi-stream the transmission of images at a high bandwidth speed of 400Mbps. It also offers the potential to record and store, via 12 internal hard drives, video captured by 64 x 2 Megapixel cameras for up to 108 days. The internal hot-swappable hard drives support RAID5 and RAID6 recording, which provides protection against unrecoverable read errors as well as whole HDD failure.

South Africa's medical blood center provided Hikvision value-added performance

South Africa's medical blood center provided Hikvision value-added performance

Editor / Provider: Hikvision | Updated: 11/6/2014 | Article type: Commercial Markets

Located in city of Pinelands, South Africa's Western Province Blood Transfusion Service (WPBTS) is a non-profit, independent organization operating throughout the Western Cape. However, in reality, this is largest blood bank in the nation, and shoulders a medical responsibility commiserate with this status.

Annually in charge of over 165,000 units of blood, the WPBTS operates in accordance with both the World Health Organization's international standards and local South African national law to assist patients with their medical needs.

In late 2011, the WPBTS contacted South African security installer Verivision to develop a hybrid solution that would:
* ensure that sensitive medical areas are continually monitored
* logistically monitor the packaging and dispatching of blood stock
* monitor the movement of individuals throughout the facility

Interestingly, from its very inception, this solution was meant to transcend the traditional goals of a normative security. This is to say, instead of only stopping bad guys, this WPBTS solution is intended to be a value-add and bring logistical benefits to the medical facility. This is not to say that security was de-prioritized; instead it is meant to highlight the multi-functional IP role that Verivision aspires towards.

iVMS Smart Search
A big part of this value-add was the logistical tracking of blood packets.

In this case, it was a Hikvision software feature that helped facilitate this aspect of the solution. Specifically, it was Hikvision iVMS-4200 Software's "Smart Search" feature for both the facility's existing analog and IP cameras.

Essentially, this feature provides motion detection, in a specified area, for security functions. In the case of the WPBTS, cameras are trained onto a certain area containing valuable blood stock; if activity occurs, Hikvision's DS-8132HFSI-SH Standalone DVR is programmed to start recording a particular camera's video feed.

Furthermore, if a bookkeeping incongruence is later detected, Smart Search allows the Material Manager (the individual largely responsible for the day-to-day and managerial duties associated with this IP CCTV system) to quickly search for the associated video based upon related date & time parameters.

Keith Lewis, owner of Verivision, noted, "In many respects, this Smart Search feature is the key to the entire solution. Of course, it is only one of many aspects; however much of the hardware and technical work that went into designing the overall system was based upon the idea of efficiency. Smart Search very much epitomizes this efficiency, and has improved overall security while concurrently reducing shrinkage [loss] by a large margin. We are even able to better ensure laboratory standards are more efficiently met with WPBTS blood resources."

Keeping with the DS-8132HFSI-SH, Mr. Lewis explained that in the WPBTS, the CCTV system has a unique internal design. Essentially, the CCTV system is maintained by the Central IT Department. In turn, the aforementioned Material Manager has an office in close proximity to this Central IT Department, and is connected by fiber-optical cable. Through these means, the Material Manager has the facility's lone client PC used to access any live or recorded video that is deemed of importance.

The WPBTS requires video storage of anywhere between 50 - 90 days. With the medical importance of this facility, Mr. Lewis stated, "I only want the best possible resolution for both live and recorded views. This is why I chose the DS-8132HFSI-SH - it gives me 4CIF resolution real-time recording and an HDMI/VGA output at 1920×1080P resolution ... the best resolution possible for any of the analog cameras in this medical facility."

Current and Future IP Possibilities
Hikvision's DS-9632NI-ST Embedded NVR was selected to allow the facility's IP cameras to function. As can be expected, Mr. Lewis expected nothing less from this NVR model. With up-to 5MP recording resolution, and identical HDMI / VGA output as the previous DVR, he was not disappointed.

Additionally, this NVR provides the ability to add 32 IP cameras to the overall solution, providing both an element of foresight and fiscal practicality for whatever the future may bring.

IP Eyes
Placed in critical areas, such as the blood dispatch / transport area, and biometrically-secured access control stations, Hikvision's DS-2CD2012-I 1.3MP IR Mini Bullet Camera relies upon its excellent high-resolution capability to provide quality images.

Almost antithetical to this 1.3MP technology is an equally important aspect: the DS-2CD2012-I's small, low-profile design. Mr. Lewis elaborated, "Since this model is primarily in main passageways, we wanted a camera that did not ... stick out. Instead, the goal was for a durable, unobtrusive camera that does a great job ... and with its IR ability, it had no problem doing this job in the middle of night, when the facility is locked-down and lights are off."

Adding the proverbial cherry-on-top, is the Hikvision DS-2CD7153-E 2MP Mini Dome Camera. Placed in the Transport Control Room, a logistical nerve-center of the medical building, the DS-2CD7153-E is responsible for keeping a visual record of exactly who is entering the building, and exactly why they are doing so.

In this transport control room, Hikvision's 2MP resolution mini dome is able to easily view the attendant's activities. A clear view of the logbooks and of people in the area. Providing a super wide angle view, this IP mini dome camera is both a security and value-added logistical benefit.

LILIN secures one of the largest university campus in China

Editor / Provider: Sponsored by LILIN | Updated: 10/27/2014 | Article type: Hot Topics

Background
Sun Yat-sen University was founded in 1924 by Dr. Zhongshan Sun, a great democratic revolutionary leader in the 20th century. The university, located in Guangdong Province, China, is a comprehensive multi-disciplinary university, including the humanities, social sciences, natural sciences, technical sciences, medical sciences, pharmacology, and management sciences. The university currently has over 82,384 students and 3,456 staffs.

To provide ubiquitous surveillance and ensure their safety are a top focus for the Sun Yat-sen University
Sun Yat-sen University is considered as one of the most important universities in China. The university recognized that a centralized approach to the maintenance and control would create safer campus environments. Security is a must to protect students and staffs on campus even though the campus area itself is relatively safe. The campuses comprise a total area of 500 acres, and, unfortunately, the old analogue system could not provide the appropriate video surveillance overview. After careful analyzing their needs, the university then decided to upgrade the outdated analogue cameras systems to advanced analogue CCTV systems and IP solutions from LILIN.

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 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.
