GEC, based in Tripoli, is responsible for the generation and supply of power to 1.1million customers across the country with the stated aim of using the latest technology to improve efficiency and reduce operating costs.
The latest security upgrade project, handled by leading Libyan integrator Al Saraya, gives GEC significantly improved surveillance coverage around the perimeter of its HQ facility.
"The Computar H16Z motorised lenses are being used at the site to achieve sharp images at ranges of 200 to 300 metres, giving the most cost-effective method of coverage in tough environmental conditions," explains Hassan Ahmed of CBC. "Fitted to an array of PTZ cameras these specialist lenses allow the operators to get detailed close-up shots of any object of interest across a very wide area."
The zoom lenses feature glass optics for higher resolution images, spot filters and a wide F range for the best quality pictures in all light conditions, from darkness to extreme sunshine.
In total 17 cameras, fixed and PTZ, are being monitored from a central control room at the site, with two new Ganz ZR-DH DVRs providing the latest in flexible record and play-back capability.
The ZR-DH models give high resolution digital recording at speeds up to 60/50 images per second with NTSC/PAL formats plus instant event replay. Recording can be set manually, with a timer, or via alarm triggers, with event archiving to a compact flash card. A LAN interface allows recordings to be viewed remotely, and the DVRs also have an audio recording capability.
Al Saraya has also supplied GEC with a Ganz ZP-TX matrix system to provide control of all the new cameras and allow for future expansion to up to 96 cameras.
"The ZP-TX system was chosen because it provides a range of features normally only found on high-end, complex systems yet it is simple to operate and extremely robust," added Hassan Ahmed.
Alarms can be added to the system using up to 96 inputs, with alarm cards distributed along the RS485 bus for simple wiring and installation.
Most popular PTZs and dome cameras can be controlled by the ZP-TX, with protocols built-in.
