hello good afternoon ,,, I have a dvr with a 1tb disk of gadnic brand ,, with 8 cctv cameras ,,, all connected by utp network cable, cat 5e ,, with their respective baluns ,, 5 I have connected in a radio of 25 meters and the other three in a background at 35m or so, I put a 12v 20 amp source apart, ,, the problem I have is that the dvr is usually restarted alone ,,, and with the passing of the hours (several hours), they are leaving to see some cameras ???? until there are two or three ,,, the dvr is located in the kitchen above the modular ,,,,,,, thanks for the help pd: if I turn it off and turn it on, turn on 7 of the 8 cameras, and so it lasts a few hours and as I said before they go off until only 2 or 3 remain, thank you and I hope you can help me
