thanks for that. The PC consumes more power anyway, so it will be good to get rid of it. Will get the DVR first.
Do you have any recommendations for 5 in 1 HD 4k DVR and the cameras?
Also I have just noticed that we have a multitude of sky wires all over the place under the roof parapet. We no longer use sky, and sky will eventually abolish the dish as it uses broadband. As I can access these areas from the loft and drill a small hole for the power cable, could I use the sky wire for the signal. I understand sky use RG6 coax and most CCTV is RG59, so this would give more shielding. I would just need to use the correct adapters on both ends or crimps.
Thanks
