The PoC-P204 M16204 video and power transmitter/receiver set is used to power four security cameras with 12 VDC voltage over four coaxial cables (max load in one channel: 1 A) and transmit/receive the composite video signals from the cameras over the same 75 ohm coaxial cables (RG-59 or higher quality) at a distance up to 800 m. The maximum distance of 800 m has been reached with the use of Camset and Triset-113 cables.

The kit includes:

The central unit (A) injects the supply voltage from the integrated AC/DC adapter into the coaxial cables, via the CH1...CH4 connectors. The units (B) separate and regulate the output voltage for the CCTV cameras (12 VDC standard) and add the video signals to the transmission lines. The video signals are transmitted over the same cables to the central unit (A) that conveys them through the cable (D) to a DVR.

The Etrix PoC-P204 M16204 set can be applied for 4 analog PAL cameras with 12 VDC supply voltage and current consumption up to 1 A (each camera). In short, the coaxial cables carry the power from the AC/DC adapter to the cameras and the video from the cameras to a DVR.

Notice!

PoC (Power Over Coax) is a technology that allows simultaneous transmission of video signal and power over the same coaxial cable. To implement this type of transmission, a pair of devices has to be used, power injector and separator. The separator also amplifies the video signal from the remotely powered camera, which allows for larger distances of video transmission than in the case of a passive transmission line, up to 800 meters.
