IndigoVision’s IP Video Solution Guards The Grand River North West Remand Prison In Mauritius

IndigoVision installed fifteen 9000 PTZ cameras and 104 analog cameras The Grand River North West remand prison in Mauritius has vastly improved security by upgrading its CCTV system with IndigoVision's IP video solution. IndigoVision's local partner Brink's (Mauritius) Ltd worked with the prison's management team to identify the ideal solution to make sure all parts of the prison could be seen, and incidents spotted immediately. Fifteen 9000 PTZ cameras and 104 analog cameras have been put in place, connected to six NVR-AS 3000 Network Video Recorders and 104 standalone transmitter/receivers. Recording is 24/7, and retained for two months. Activity Controlled Framerate (ACF) is used, with a bitrate of 512kbps for recording. The IndigoVision network now covers every single area of the prison, and gives greater coverage inside and out than the previous network. IndigoVision's integrated motion detection, alarms and mapping is also a major advantage, letting operators quickly spot problems and identify exactly where things are happening, while playback of recordings is easy and immediate. "The IndigoVision network gives a real bird's eye view of all that's happening inside the prison - in rooms, corridors and gathering areas, and also outside in the parking lots and round the perimeter - while the alarms and motion detection make sure nothing is missed. It's a vast improvement on security, with two remote control centres ensuring maximum security control in all areas," says Brink's Mauritius project manager Vikash Augnu.   IndigoVision's IP video solution was chosen for its ease of use, stability and reliability Workstations are located in the prison's main Control Centre and also in the main gate and towers. A new network LAN has also been installed, using both fibre and FTP cables. The compact NVR-AS 3000 Network Video Recorders have a small footprint but are powerful recorders. They can record up to 20 cameras at full frame rate with audio and simultaneously play back up to 20 cameras, with extremely low power consumption and heat dissipation. ACF controls the framerate of the camera video stream based on the amount of motion in the scene. When there is no activity, video is streamed over the network at minimum framerate. The instant motion is detected the video is automatically transmitted at the maximum configured framerate. This significantly reduces the bandwidth and NVR storage requirement for cameras monitoring generally static scenes or during quiet periods such as at night. IndigoVision's technology was chosen because it is simple to use, and known to be stable and reliable. The tough environment needed a robust solution that was easy to install and maintain. Image quality was also a key factor for guards monitoring a large number of prisoners.

MetrôRio Use IndigoVision IP Video To Protect The 700,000 People Who Travel On Its Network
MetrôRio Use IndigoVision IP Video To Protect The 700,000 People Who Travel On Its Network

MetrôRio, Rio de Janeiro’s metro system, has chosen IndigoVision to supply a complete IP video security solution to protect the 700,000 people who travel daily on its network and to allow for future expansion of the metro service. IndigoVision won the contract to replace MetrôRio’s ageing analog surveillance system because of the superior image quality of the IndigoVision cameras, which makes for precise identification of individuals in recorded images, coupled with the flexibility of the IP system, which can be easily scaled up as the metro network grows.    Mr Newton Werneck, CIO of MetrôRio stated: "IndigoVision's image quality is excellent and the distributed architecture of the system will allow the surveillance network to grow along with the metro system." Another crucial factor in winning the business with MetrôRio is the system’s highly efficient and economical storage capability. Compared with other IP video systems, storage requirements are significantly reduced thanks to IndigoVision’s advanced compression technology and the use of the unique Activity Controlled Frame rate (ACF) feature, which is built into the IP cameras. ACF regulates the frame rate of the video stream according to the motion in a particular scene. When there is no activity, video is streamed at minimal frame rate; the instant any motion is detected, video is simultaneously transmitted at the maximum configured frame rate.  This responsiveness provides both greater detail for analysis and also allows for economy of data storage.  The IndigoVision system also provides MetrôRio with improved event archives and content distribution across its network: IndigoVision’s unique distributed architecture eliminates the need for a central server, which means that the surveillance system can expand quickly and as required. IndigoVision’s Brazilian partner Setha Prosegur worked with MetrôRio to create the surveillance system, which includes 141 fixed IP cameras, 21 PTZ cameras and approximately 700 existing analog cameras that have been integrated into the system using IndigoVision encoders. An IndigoVision NVR-AS 3000 (network video recorder) is in place at each station, with back-up provided between stations. Founded in 1979 with five stations operating on one line, MetrôRio now covers 47km (29 miles) divided into two lines and 35 stations. The network continues to grow with a further line under construction and due for completion in 2016.  

Solution From Bosch Security Protects The End Of The Line
Solution From Bosch Security Protects The End Of The Line

Bosch products chosen for security at  London Southend Airport An entire portfolio of technologies from Bosch Security Systems - including the PLENA range of Public Address/Voice Alarm (PA/VA) technology - is being installed at the new Stobart Rail operated railway station at Stobart Group’s London Southend Airport to protect the safety and security of passengers and staff.   The station and airport, which was acquired by the famous transport and logistics group in 2008, features the Bosch range of Projection Speakers and Metal Cabinet Speakers to ensure effective communications with passengers, whose numbers are expected to rise to more than two million by 2020. The site is also benefitting from a surveillance system which includes the first installation of its new digital hybrid recorder (DHR).   Project Managers Birse Rail appointed DACS Rail as Electrical Engineers on the project who in turn appointed Max Electronic Systems to design and install a safety and security system that was fit for purpose today, but that could be relied upon to still be operating efficiently in the future. For that reason, Bill Anderson, Managing Director of MAX turned to Bosch: “When Stobart first purchased the site, it was obvious that security would be paramount,” he says. “This major new gateway for the South East now has a security and communications solution that is at the cutting edge and will be further upgraded as technology advances. “Bosch products are at the centre of everything we have done; the proven reliability and quality of its technology is exceptional,” he adds. The railway station has been expanded as a direct result of plans to upgrade London Southend to handle larger aircraft, and therefore more passengers, requiring the highest specification CCTV.   At the heart of the CCTV system are 20 Dinion XF Colour cameras, 15 Dinion 2xDay/Night cameras, three video interconnect portals and three LCD TFT monitors. It is also the first site in the UK to use the new DHR technology. In terms of delivering the messages and audio throughout the station, Bill opted for the flexible but entirely scalable Plena Controller which forms part of the PLENA communication family, including a remote control panel and zonal microphones.    The railway station is also covered by Bosch Speakers, with Projection speakers located upon the platforms and Cabinet speakers within the waiting areas. The Bosch 700 Series (formerly Divar XF) is a highly scalable system recorder for medium to large applications. It is a realtime 4-CIF embedded recorder, available in hybrid (analog/IP) and IP-only versions and utilizes state-of-the-art H.264 compression to deliver bit rates that are up to 30% lower than conventional MPEG-4 based recorders.
