Do the cameras require a power supply near to installation location?
Alick, Timperley
The cameras do not need to be located near a power supply as they receive their power from the DVR. The cameras connect directly to the DVR via the 18m BNC cables.
How many meters can I put the cameras from the DVR would 60-70 meters be fine?

I would always recommend a maximum distance of no more than 60 metres and with a single BNC cable Swann 60m CCTV BNC Camera Cable, as using different lengths can effect the resolution and quality of the picture.
