Hikvision PoC
Hello!
Firstly I'd just like to say, I don't really know what I'm doing here, I'm an IT tech with a desire to tinker!
A friend's mum called me round to fix her CCTV, Hikvision DVR with 2 3K ColorVu Fixed Turret Camera (DS-2CE72KF3T). The DVR was dead seemingly, no video out of HDMI or VGA, no access from the app, but was networked correctly etc, not knowing what I know now, I advised her to replace the DVR, unfortunately I didn't realise that the cameras were being powered by this Hikvision proprietary Power over Coax, meaning the cameras on the new DVR have no power. I don't really want to be drilling holes through her wall to get power to these turret cameras, so (refer to photo), I was wondering if there was a way I can use a specific type of baluns, and send 12v power up it, using the existing spare pairs from the ethernet cable, thus allowing me to power the camera with existing wiring - or if anyone can just offer general advice on a way forward that doesn't involve her dropping another £150 on a new DVR? Thanks in advance
