Power for cameras ?

[ottosump]

Hi group, I'm looking to install a small domestic CCTV system (approx 4 cameras), I understand that you need a video cable to run to each camera, but where do the cameras get their power from, is it supplied from the DVR or will I have to locate a power source in my loft for each camera?
Regards Otto

Could well be Ethernet connected in which case it would be PoE (power over ethernet)

Or power over coax .... hikvision support both types ....depending on dvr/nvr
And camera type ...
Or 4 way psu in loft
