mfb1 0 Posted August 1, 2019 Hi, I have a Sentient 8channel DVR, bought from Maplins 5 years ago. At present I only use two channels on the DVR, one camera at the front of house,and one at the rear. Seems to be a problem with the camera at the rear,in that there are horizontal lines across the monitor, but not that bad that I cannot see images okay though. The other channel is okay, and shows normal on the monitor. So just wondering if there is a problem with the camera. I do have a spare camera that I can try, but if I need a new camera, what type would I need. The one at the rear is a 420TVL camera,so not hd. Also everything recording normally.
