still with the problem any other ideas?

i'm not sure but, if you said the power supply really gives you the 12v at each end, i think the problem could be the video connectors, focus on that. i would check the video cables and connectors at each end (Camera and DVR) and check if the video comes in or out every time you adjust some cable/connector, if so, you'll know what's the problem here. hope you can fix it ! cheers!

Are you sure that the problem is the power supply? Give the BNC connectors at each end a bit of a wriggle/jiggle just to make sure they have been done properly.

You can check the voltage at the end of the cable near to the camera so you can see if you are getting the 12V really.

Thanks myiicu 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.

I dont know if this is the correct place to post this but i need help with this, i have a cctv system but the software that i use from (DAHUA) has only 8x of playback speed, is there any software that i can use above of 8x? like 16x? i dont have too much experience in this so i dont know if theres something like this or the software and the video players max playback speed is 8x.

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

i dont have phisically access to the cameras at the moment, the model is DAHUA HFAW2200B36

i'm getting problems with the image on some cameras, problems like blue and ghost image, so i went directly to the power supply and turned it off, then i turned it on again and now i get perfect image on all the cameras, then in about 5 or 6 hours it happens again . I need some advices on what to do.

I have 10 Cameras installed on my DVR (7 Bullet, 2 Dome, 1 PTZ) all cameras are connected to a power supply, only ptz has an external power supply. I'm having problems with one bullet camera. There's too much interference on it. Sometimes the image has good quality, sometimes is really bad. Brand: Dahua (All cameras and DVR)

There's no an hour for this, that's why im starting to thinking about that maybe there's an electric equipment outside causing in interference when this is on.

The power Supply is new. What you mean by "clean"?.

Thanks for the reply. Rebooting the DVR does not solve the problem, the camera is still with the same image. The rack, i dont think that could be the problem, in that case the rest of the cameras would have interference too. By the moment i only have access to the DVR setup, so i can't test the cameras directly. I think i have to get to the roof and check there's not some electric equipment making the interference with the line. Im not really an expert in all this, actually this is the first time that i own in my office an equipment like this. I mean it's not really hard to understand the functionallity of the system, that's because in 3-4 Days i learned alot. But when we talk about "Interference" there's a world of causes. That's why im here If you have another idea, please let me know. It will be helpful to me. Thanks again!

How much upload speed do i need to see perfectly all my 10 cameras in 720p, 15fps?

Nothing is wrong with the BNC connectors,I have some equipment on the same rack where my DVR is placed (2 servers, 3 Switches, 2 Modems, 2 Routers, 1 Battery, 1 Access Point) Could this equipment cause some interference with the dvr or connections? Also there's an AC above all this.
