Hi all, I have just installed a dvr with 8 cameras, at my fathers, in the day time all the cameras are perfect, apart from 1 having a jittering line on the screen at the top of the picture. Then at night is where all the issues start, 4 of the cameras are fine, but the other 4, is another story. The 2 at the back which are on 40m cables, its like the ir's are only half working, as the picture is black, the other 2 at the front are working day and night, but its as if it is snowing at night. Any help would be much appreciated. Regards Mick

Ok I will try that this weekend coming and let you know cheers

Thanx for a speedy reply, would you be able to suggest a power supply, that would take care of these
