CCTV you cannot slip past

August 2009 CCTV, Surveillance & Remote Monitoring

Radar-camera systems provide better protection for perimeters and open ground.

Linking the detection power of the latest radar technology with the 24/7 image-capture capability of CCTV cameras, the new Navtech/Ganz C-Allview combination delivers a new defensive layer to any perimeter or area of open ground. It suffers from none of the shortcomings of traditional perimeter detection techniques and, compared with most of them, it is easy to install and maintain.

The Navtech-Ganz system will automatically detect, track and record people as they enter a specified zone, and continue to keep them under surveillance as they move about. With a detection range of up to 800 m, around a full 360°, the system will operate unhindered in adverse weather conditions such as rain, snow or fog, across most terrains, including water, and at any time day or night. And each radar unit can control five separate C-Allview cameras, allowing multiple threats to be monitored simultaneously.

The system offers operational advantages for security planners. It can significantly strengthen conventional perimeter defences, sitting either back from the fence, or at the fence line itself, to ensure totally reliable detection and surveillance of intruders as they approach, attack or penetrate the boundary. Equally it can be used where fencing systems cannot be deployed at all, such as in the grounds of private residences, where the visual impact of any security system has to be kept to a minimum. By automatically controlling cameras and DVRs – recording only incident footage – the system allows the most efficient deployment of both equipment and manpower. It warns operators whenever a human target enters the detection zone and it continuously tracks them when they are in it. The attention of the operators can thus be focused on ensuring the right response is made, and as quickly as possible, but only when that response is actually needed.

The Ganz C-Allview is a compact, ruggedised PTZ camera designed to operate in the toughest conditions. With its distortion free, optically flat glass, built-in wipers, and IP67 rating, it is designed to deliver crisp, clear images in situations where other models might struggle. With the recent launch of the dual optical/thermal C-Allview, man detection images can be seen up to 1 km away during the day or at night and through fog or other adverse weather conditions.

CCTV lighting for power station

New adaptable infrared illuminators supplied by CBC (Europe) have been installed at Eggborough Power Station to improve the night-time surveillance of security camera images monitoring the British Energy-operated 2 GW coal-fired power station, located near Selby, North Yorkshire, in the UK.

The IR/500 series long-range infra-red LED illuminators supplied support 13 pan/tilt/zoom (PTZ) CCTV cameras which survey various access gates around the site perimeter, as well as various entry points and other high risk security areas.

Prior to installation, the CBC illumination units were required to pass a number of in-situ field tests to ensure they met requirements set by Ian Beechcroft, British Energy’s head of Environment and Safety. The IR500/2060 model specified allows the angle of light projection to be altered between 20° to 60° and provides night-time illumination up to 100 metres at 60° (wide), and 160 metres at 20° (tele). The infra-red units supplied have been fitted to existing 0,5-inch colour-mono cameras and Computar zoom lenses.
