Dear All,
I have recently installed CCTV camera set on my premises and I am having almost daily problems with picture quality.
Some cameras are displaying fuzz/distortion/wavy horizontal lines
Some cameras are displaying flickering image in B&W along with a thick black vertical stripe/line almost always on the right hand side of the image.
I have searched a few forums and from what little I could gather this could either be a ground loop problem or a power supply issue.
Please excuse my ignorance as I am a total novice here.
I have taken the liberty of attaching a short video which shows the problem amongst the 4 cameras.
CAMERA 3 & 7 -- heavy flicker/distortion along with right hand vertical black bar

CAMERA 5 & 9 -- fuzz/wavy lines

The box is a ALHUA (ZHEJIANG DAHUA VISION) COSMIC HD DIGITAL VIDEO RECORDER WITHOUT HARD DISK
MODEL: DH-XVR4116HS
The cameras are: HIK VISION COLOUR CAMERA
MODEL: DS-2CE1AD0T-IPRR
Appreciate any feedback as this is really driving me crazy.
Thank you Gerard
