Blue Image

[logicrussh 0]

Im having a problem with one of my cameras, i got 10 cameras on a DVR, but one of those is sending blue image to the screen, i dont know if this could be a problem with the power supply or some kind of interfierence. Can you please help me with this?

 

some other data: when i turn off the power supply, al the 10 cameras send high quality image and everything is good, but in about 4 or 5 hours one of the cameras gives me this problem (Blue image), thats the only camera with that problem so im starting to think that the problem could be that camera specifically.

 

Hope to get an answer and im sorry about my english level

Try swapping out the power connection at the power supply of the suspect camera with a known good connection.

 

If the problem (blue image) occurs again with the same camera, your camera is NFG...

I already do that, but the problem persist. What do you mean by "NFG"?

Hi. Blue screen might not be a power problem .... But it takes 6watt can you list or post a picture of your power unit

 

 

Distance of your problem camera to recorder ?

 

But blue screen sounds to me like data problem .... Are you running everything on highest settings on all 10 cameras ?

 

If so for a test knock down 3 or 4 cameras to 720p and see if you have the same problems

Now i have 2 cameras with this problem, one camera in each DVR (Yes i have 2 DVR, reason: Distance).

 

1.- Both cameras are between 200 and 260 fts of distance from DVR.

2.- Yes i have all cameras on highest settings.

 

I'm gonna try to do your suggestion.

Now i changed the power cable of the affected camera to another place on the power supply, everything seems to be good now, i'm going to wait a couple of days to see if that was the problem.
