integrated12345 0 Posted April 21, 2015 Hi, this is my first post to the forum, I have a PTZ Camera (Link below) and when it activates night vision the IR LED's come on for a few seconds then flicker then turn off and the camera goes into a System boot menu, it does a few tests then it will repeat this over and over till day light, any ideas what could be causing this problem? it functions fine during day time but as soon as its dark the camera plays up, i am still waiting for a reply from the Seller. http://www.ebay.com/itm/Outdoor-IR-PTZ-Camera-12X-zoom-700TVL-Waterproof-Speed-Dome-Camera-US-Location-/151597332890?pt=LH_DefaultDomain_0&hash=item234be7b99a also i have experienced a 15mm line of interference in my other 3 bullet camera's, i am just wondering what could be causing this, does 240v Mains Power cause interference? is it worth buying a BNC Video Ground Loop Isolator like this one: http://www.fishpond.com.au/Electronics/VideoSecu-Passive-BNC-Video-Ground-Loop-Isolator-Noise-filter-for-CCTV-Security-Camera-Surveillance-System-1MU/9999420020890 thanks for any suggestions or help guys.

abdelm01 0 Posted April 24, 2015 How is the camera connected to power? Sounds like its not getting enough amps to keep those IRs on. Might want to try to plug the power into a sockets thats on a different breaker with no power consumption on it to test if its a power issue. Share this post Link to post Share on other sites
integrated12345 0 Posted April 26, 2015 I ended up just changing the video cable to 75ohm and it fixed the problem, as for the ptz camera they might be sending a replacement. Thanks for your reply. Share this post Link to post Share on other sites
