Besides, DVR provides auto-detection of PoC/Non-PoC camera, supports over-current alarm and its protection, status of PoC operation.By using WEBGATE’s recommended 5C-HFBT coaxial cable, PoC cameras can transmit HD-SDI video up to 200m. Moreover, PoC repeater RP101P can be used to extend the transmission distance. RP101P is a repeater which supports PoC function and because its power is supplied from DVR, it can be located anywhere without any restriction of installation.

      •  Power through coaxial cable from DVR to camera
      •  No additional power supply 

CoC (Control over Coax)

Not only PoC function but also camera control can be executed through coaxial cable. Cameras do not need additional RS-485 cable to control camera, so PoC camera’s OSD menu control, Zoom/Focus control and firmware upgrade can be executed by coaxial cable. In case of PTZ dome which requires somewhat higher power consumption, only CoC function can be utilized interfaced with RP101P.

      •   Camera control through coaxial cable from DVR to camera
      •   No additional RS485 control line
      •   Controls OSD menu, Zoom/Focus, camera firmware upgrade
