Camera problem, flickering, horizontal black lines

[mikecad 0]

Hi there,

 

Hoping someone here can help, I have a two camera set up feeding into a DVR. One camera is fine however the other experiences problems. At a certain time of the day the display starts to flicker, there is colour bleeding and horizontal lines moving slowly up or down the display. It appears to be related to a particular light level as it begins to darken outside. I know it is light level related because the times it has been happening have moved from around 16:30 in the winter, through to about 21:00 as of now. During the daytime it is fine. The problem has been occuring for around 6 months now and is getting steadily worse.

 

Both cameras are external, I'm just wondering if there are any particular areas I could look at? Is this a common occurence?

 

Regards,

 

Mike...

Try changing out your power supply to a new one.
