Hi, hopefully someone more experienced can assist...
I have a Hikvision DVR with four 1080p TVI dome cameras. Three are perfect but one has about 12 wavy lines particularly noticeable at night. Here's what I have tried:
Swapped over two cameras - problem is not with the camera
Swapped inputs at the DVR - problem is not with the DVR
Tried different PSU's both regulated and switch mode
Tried a higher quality heavier cable (20M pre-made combined power and video)
There's nothing in the area or along the cable route (electrical) that I can see that would be causing the problem. I've attached a screenshot if this helps.
Thanks in advance.
Steven
