I can see if someone I know has one. My multimeter skills are limited. Do you think I should test the output of the power supply? EDIT: I ordered a new power supply on Amazon prime, this should rule out if the current power supply is faulty. I certainly would. You have no idea what the power supply is actually outputting - in the past, I have tested all sorts of cameras at different voltages (with a variable voltage power supply) and some of the results were a) really weird and b) unexpected!! It's a good idea to know what you know (if that makes sense!!). The multimeter is giving a reading of 12.36 volts and 8 amps. Any advice on what ac/dc adapter to get? Thank you for the feedback. I also believe that's what might have happened. I'll probably try to get another power supply (if one is recommended). It would be cheaper that asking a tech to come out.

I was also thinking maybe PAL/NTSC got messed up. I took down a couple of cameras and brought them home with me. Then used a "bnc to rca" connector and hooked up the camera to a couple of TVs around the house. The picture looks the same. My thought was that N.American TV should be NTSC. And the cameras are NTSC since they have an NTSC sticker on them. This way I eliminated the DVR from the troubleshoot. Also to note, I didn't find NTSC/PAL option in the camera settings. Camera settings can be accessed via a dongle that is attached with another short cable to the camera. One thing I just noticed and not sure what it means. If I try to access the settings menu (on the camera, via the dongle), the settings lettering is clear and not fuzzy like the rest of the picture. :/ This happens at all times of the day. Most camera's pictures are very much like the one I attached. Some (maybe 2) are worse, not sure what the technical term for it is, but the picture looks like shades of black and white, very concrete, no fuzziness.

Hi everyone, First post here. Noticed this community when looking for answers and was hoping someone can put me on the right path. My mom had a "no brand" DVR and 8 CCTV cameras (purchased on ebay) setup about 4 years ago. One day, all cameras went offline, no picture, while DVR was still working. I checked the power supply for the cameras and it was dead (All cameras a powered by one supply using a this type of splitter, http://bit.ly/2tk52z6). I bought a new power supply on Amazon with the same voltage and amperage as the old one, that seemed to fix the problem, but a few days later all of the cameras started to show an odd picture (attached). It appears that its somewhat pixelated, fuzzy, wrong color. Some cameras are worse than others. My hunch is that I bought the wrong power supply and fried the cameras. I thought I did the math right though. Each camera requires 12v / 750-800mA based on the manual it came with. I bought a 12v / 7.0A power supply. Could a cheap power supply overheat/break and do something like this? Has anyone experienced or seen a similar issue? I'm a little stumped, I figured if the power supply damaged something, cameras would just die, but I have zero experience in this field. Any thoughts or ideas are welcome. Thank you.
