CCTV DISTORTED IMAGES --- NOVICE USER

Recommended Posts

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

Over 100 meter on a poor quality coax cable?

2. Power Supply is sufficient for IR and Good Groundings for each camera.
