Dnallov 0 Posted October 27, 2008 We’ve been replacing some suspended ceiling tiles, and some had these dome cameras in. They had to be disconnected so that we could replace the tiles. There was 3 wires, consisting of a supply and the coaxial. We connected them back up and now they don’t work . Can anyone give me some ideas. Thnaks! Share this post Link to post Share on other sites
scorpion 0 Posted October 27, 2008 Do you have some kind of small monitor / tv that you can hook up right there at the camera? If you get video then the power side is ok, and you have a video transmission problem. If you do not get video then you have to check the power to see if is getting to the camera. If you have power then the camera is bad. Since you have more than one camera out then I would suspect a power issue. What do you think? Share this post Link to post Share on other sites
griffonsystems 0 Posted October 28, 2008 could have blew the fuses at the powersupply if they come back to a central supply or check ur coax connectors Share this post Link to post Share on other sites
survtech 0 Posted October 28, 2008 Most likely you have power supply issues. It is very common when disconnecting cameras to short the power wires, either to each other or to a ground. That will blow fuses. It happens to us all of the time, even if we take care to separate the wires. Share this post Link to post Share on other sites
