Post subject: Camera Keeps Dropping Video Signal
|
I bought 2 of the GS232B cameras form Gadspot. One worked fine and the other was not as sharp. So I paid for shipping back to Gadspot and 2 weeks later they sent me a replacement. The new camera they sent seems to have a problem, after awhile I get a video loss. I went out at night and can see the led's lit even though the video went out. So I assume there is power. If I unplug the power supply and plug back in, the video comes through again for awhile , then I get a video loss again. This can be from 30 minutes to 4 hours. Also if I undo the BNC connector on the back of my recorder and reconnect, leaving the power supply hooked up, does the same thing, video reappears then after awhile it goes out again.
What could be causing this problem.
Really appreciate any info on this.
Ted

What kind of wiring are you using?
What kind of power supply, or power supplys are you using?
The reason I ask is this:
Wiring:
I am going to assume that you have premade wiring. This is the kind of wiring that does not require any assembly, or know as Plug, and View wiring.
Do they have a BNC to RCA adapter? You may have some bad ones that need to be replaced.
Power supply:
Do you have a box, or do you have wall wart transformers?
You may have dirty contacts on the plugs at the power supply, or at the camera end.
If you are going more than 100 feet, then the wall wart transformers may not be pushing enough juice. What are the transformers rated at?
250 mA? 500 mA?

QUESTION: Why is there always enough time to go back and fix it right a second time??

I just had this exact same symptom on on of my cameras today.
If I disconnected and reconnected either end then the video was restored for anywheref rom a couple minutes to a couple hours.
Turned out that mice had eaten then coax.
Can you account for every foot of the wire? Is it possible that there could be a damaged section that is hidden??

sir you can use a time domain reflectometer to check the cable. it will tell you how long is the wire. so if it is less than what you got before you know where the broken line is.
