I have used combined power, video and audio cables to install my CCTV. However on 2 of the cameras the picture quality is very poor and I think the signal needs amplifying. Is there anything anyone can recommend?
thanks in advance
I bought a second hand DVR card and installed it in my DELL 3100 machine
However the video source is found in the software but there is a corrupt display on the screen
Has anyone got any suggestions that might help me???
Thanks in advance
