adnanali 0 Posted October 7, 2009 While installing a CCTV i just connected red to gnd and black to positive of the power supply and turned it on. Now after realizing the mistake I reconnected them correctly. Now there is no video output. Is the camera damaged??? If, yes is there any thing that can be done to repair it???

WRS_Mark 0 Posted October 12, 2009 Reverse polarity is a bad thing. Some cameras, however, can deal with it for short periods of time. If you haven't touched the camera since you posted this maybe try it again. I have seen it when a camera (in this case a Discovery Camera - 480TVL IR armor dome as I recall) all of a sudden returns to operating condition after an event such as the one you described if it has been left alone for a while. If it still doesn't work, it's a paper weight. Share this post Link to post Share on other sites
Soundy 1 Posted October 13, 2009 Yeah, hard to say without knowing what camera you're talking about. Most cheap ones will almost certainly be cooked. Better ones will withstand the reverse voltage for a short time... some will actually work that way (ie. they're not polarity-sensitive). If it is dead, it's probably NOT repairable, as most cameras that would be damaged by that are small board cameras that use mostly surface-mount components.
