Nothing but trouble with the night vision (video loss)

[bmaster]

Understand about the SubHD and while I do still have mine I am saying that it is a quality machine and again as long as it is a + machine it is rare type and personally on just that I would keep it even if only for a Shelf Queen..

So sadly the next issue isn't something that everyone can do but over time IR fails and from what it sounds like in your post if a Known Good Power supply won't work the camera alone then we can root out the issue being a bad Power supply this only leads me to one last thing and that is a Bad IR board.. While the whole board might not be the issue it could be that the IR LED has shorted and is causing the camera to shut down in a way to preserve itself.. So what could you do? (Again not everyone has been in Electronics for 40 years) however if you were able to you could remove the front of the camera, My system came with 2 bullet and 2 Eyeball cameras, So not sure what one of your is bad or if your is different however the Bullet one of mine has 4 screws on the front that hold the glass on, Removing the 4 screws from front, then the 3 or 4 in side holding down the IR board unless your able to remove the wires without pulling the board out.. The Eyeball camera is easier to take apart as there is no screws holding it together just have to unscrew the front lens half off the back camera holding half and gain access to the IR board again there will be 2 wires and depending on the type of 960h cameras you have it might also have a IRC wire as well.....

Please make NOTE... Removing the IR from the camera will make the camera stay in Color at night, While you can replace the IR LED if you can find what one is bad and or it could be the Power Supply if yours has one and not just the wire connecter.. While looking at the IR Board you would know if it has power Circuit if there is more then just LEDs and little SMD resistors, There might be some diodes, transistors and other things within the IR circuit board.. If only IR leds and a few resistors then more then likely the IR led has failed causing your camera to shut off when IR comes on or is told to..

When I move the cables around, I see the image come on sometimes for a few seconds and then it goes off again. I thought this meant perhaps the connections were loose. But when I fiddle with the connections of the cables themselves, it doesn't seem to make any difference at all. It's only when I start moving the whole cables around randomly that I see a change. I think I might just let this go at this point and get a different system. I don't know if I can use the same cables, probably not. At least I already drilled the holes. This stuff is so tedious though.

Well for future info when pulling cables it is a good idea to pull Cat5e along with your BNC cables.. If for some reason there is an issue with your BNC cables one could use the Cat5e with Balun connectors.. So here is the next question and I know not many people have the cameras next to a power supply but did you by chance use your good power supply at the camera for a night to see if maybe the cable to the camera is the issue..

Some of these cables are a 3 wire cable, 1 power wire 1 video and the common ground for video.. Lets say that your cables are a few years old and pulled into an area that was tough to get to when pulling it stressed the power cable, Once some time past that stress now as caused that to fail, With your cables being bad from stress it might work under a small load but when the IR comes on there isn't enough wire left to give the power and fails..

Sadly it is hard to say.. The cables are ok for the next system if you use same type of hardware (that needs BNC) however if you move over to a IP camera system then new cables will need to be pulled..

Cool thing about having BNC and Cat5e cables at your camera location is that in the event you want to install new camera that is IP or even a high end PTZ camera that has Alarm in and outs and things like that you can use the cat cable for that.. Future Proof..

Sorry couldn't help more.. Wish you luck with your new system..
