Just seen this thread , we bought a Swann Advanced security system DVR4-1425tm 4 channel Digital Video Recorder & 2x PRO 535tm Cameras Advanced Series D1.
Iike I said if we wish to we could add another two cameras, one out the front, one down the side of the house but again as the police said we dont in reality need that number of cameras
The resolution on these cameras is second to non and the colour reproduction is fantastic, we could have bought a remote system but we have so much in the way of metal in the walls doorframes and windows that we doubted it would have worked but the wires are all extremely well hidden
