The DS-7216HUHI-K2/P is the new 16 channel Power Over Coax (POC) DVR from HIKVISION. It has H.264 and Duel stream video compression and uses a BNC interface for TVI, AHD, CVBS camera input. This DVR has a HDD capacity of up to 16TB. This DVR also has the additional benefit of supporting an additional 2x IP cameras of up to 8MP Resolution. Power over coax (PoC) provides power to the camera over the same coax cable as the video signal thus simplifying the cable installation and reducing time/costs. To use PoC you must use a compatible PoC TVI camera. Alternatively normal TVI cameras can be fitted with a separate camera power supply.
