bigdunc72 0 Posted May 21, 2014 Hi All, I have recently installed a dahua 23x zoom analogue PTZ at a cutomers site, however having issues with one of the cameras where it just looks directly at the floor for a random amount of time then continues on with its predetermined pattern. Video isn't lost as we can see the camera looking at the floor. Does anyone know what could be causing this? I've thought it could be an unclean power feed or maybe some surges/dips in the main supply maybe? Power is supplied via 24VDC (3000mA) PSU which is approx 30 mtrs from camera location, fed over Cat5. Would it be wise to try a more powerful PSU (and what would you recommend?) Thanks for looking.

dexterash 0 Posted May 22, 2014 IR camera? First of all, measure the voltage at the camera (what arrives) with IR on(if has) and also while moving/controlling it. Share this post Link to post Share on other sites
bigdunc72 0 Posted May 22, 2014 Thanks - It is an IR model - and like I said it's fine in the day, just bizzare how it drops off - middle of the night (not just as soon as IR's kick in). This camera is really high and I need cherrypicker to get to it - is there another way to test draw at the PSU (at low level inside)? Share this post Link to post Share on other sites
dexterash 0 Posted May 22, 2014 You can measure the current and compare it with the max current that the camera should need. If it's close to the max, something isn't ok at the powerline. Share this post Link to post Share on other sites
tomcctv 187 Posted May 22, 2014 Hi . Are you using cat5 for power data and video ? How many pair did you use for power Share this post Link to post Share on other sites
