Why this camera will not work without light around.? Tried one power supply alone for this camera still same.

It may be defective the one I have has a decent black and white image at night. You most likely won't see a light from it it records using infra red lighting at night. If it's not recording anything you pro bubbly have a bad camera.

Sounds like you are having trouble with the night vision IR. Call zmodo 800 line. They are very good. Sounds to me like the camera may have been damaged in shipping or something. It should definitely see in the dark.

The camera is powered by an AC power pack you have to plug into the wall. Any wire less camera will have to be plugged into some power source, be it batteries or AC. I recommend you look for a different wirer less camera. I bought two of these and both of them went out inside a month. The picture quality is not good at all.

Dear friend, Thank you for your questions. Please note that the Camera has no battery inside, and it is not support for battery carrying, so you are right that the camera has to be continually plugged into the electrical outlet to work. It is hope I have solved your problems. Best regards!

It sounds like the CMOS board is bad. Try a constant power supply and an only power that camera. If the problem goes away then you were under voltage or most likely under current. If problem is still there then a bad CMOS board

There may be some light shining onto the photocell. Also make sure all your connections are secure and tight. Also check your voltage for the appropriate requirements.

This could also be a ground loop- this is more common with audio connections. Try moving your ground wire to a different source. The issue is probably because the camera and the screen have different ground connections, which is basically unavoidable but you can fix it by experimenting with different power and ground sources. Or, you could buy something called a "ground loop isolator", but in my experience those usually only partially fix the problem. Good luck!

Don't know - the power consumtion is so low that I use my recargeables in a camera instead

I'm sorry Bonnie, but for some reason my message to you got cut off so here is the most important part for you. I also use it for home surveillance. The short answer to your question is NO! you cannot connect an external power supply to these cameras. Hope this was of some help. Pete

Is likely a broken wire or dirty connection. I would try the cable on another camera. If it works on another camera, the contacst on your camera are probably dirty. If it still does not work, it's probably a broken wire in the device. A broken wire in the device is unlikely to be worth fixing outside of warranty.

DO you have other cameras and are they operating alright? Naturally check all the connections both at the camera and the recorder. Also look for any nicks or cuts at the exposed wires. I experienced a problem once when all the cameras stopped working and it turned out it was the power adapter that went out. I replaced this item and it worked just fine after that. This is a good camera for the money. I have two of these and they have been working for just over a year. I'm even thinking of replacing the other two cameras with one of these so please let me know how this turns out. Good luck

Dear Valmore, thanks for your comments. I did get the external adapter and another coupler that was necessary, and got it to work on the noted external power supply. However, I found the slow-motion options to be impossible except when working under open strong daylight. Otherwise, the amount of light entering each frame was way to low to do anything with. One would have to post-process the image files to increase their brightness and contrast, so I decided to return the camera.

It can be power by either. (12 Volt power supply or POE). I get a great picture and I have the camera's outside and they have worked flawlessly in zero degree to 90 degree weather.

It needn't using Power over Ethernet,you can using the power supply which included in the package with the camera.

If the power goes out it would stop working yes. It has a switch on the side of it so if you left it alone as soon as the power comes back on so will the camera. Hope this helps!

Do you mean the monitor is connected to you backup lights? It could be that there is a surge of power upon ignition that is tripping however you have monitor power wired--but the surge isnt making it to the backup camera--and the display shows no signal because the camera isnt powered/relaying video

you must have power over Ethernet (POE) switch to power up the camera. or plug in standard compatible power source to camera.

The camera does need a power source. I did not use the power adapter because I connect the camera to my existing video surveillance system. I hope this answers your question.
