I feel like newbie at all the area of Security Cameras.
I got used to DVRs and stuff and we have been advanced to NVR's.
I had bad experience with Chinese makers of NVR's that promised their NVR can supply power to 4 cameras over 15m each and stuff like that and all of them have failed.
Correctly today i am search for a system of "Hikvision" (that's what my costumer wants) or "other big brand" with POE, 3MP cameras (8 of them), and of course NVR that can supply power over 20m for each.
I know Hikvision has great mobile Apps too so this is a good point for them.
Basically i know that every NVR should support power to the each camera up to 100m (poe cable has 12w in it - max).
if not or something like that please correct me, direct me to read stuff - I will be happy with that.
Thanks in advance mates
