Factors including low cost, compatibility with other components, a wide range of video signals and the protection of existing systems have made certain that analogue CCTV cameras are still widely used.
A compact arrester ensuring the protection and availability of video transmission systems, the DEHNvario 3in1 surge arrester, guarantees unrestricted operation of analogue camera and video transmission systems, even during thunderstorms.
Representing a new generation of arresters that protects different signals of power supply and information technology systems, the DEHNvario stands out due to its extremely flexible connection technology. This complete solution protects three interfaces in a single device: the supply voltage; data interface; and video signal. This largely eliminates an incorrect selection of devices.
The DEHNvario 3in1 solution is ideally suited for analogue cameras that require:
• Power feed.
• RS-485 feed (pan, tilt, zoom functions).
• Analogue video signals feed (BNC).
With its high discharge capacity of up to 5 kA (8/20 μs) per core, it can be used according to the lightning protection zone concept at the boundaries from 0B to 2 and higher.
