todd2 0 Posted January 29, 2010 Camera had been on for several hours and reached operating temperature. I noticed that when the sun went down, it wasn't picking up much of an image (mostly black). It was a low lux camera, so I was confused. I unplugged it, quickly plugged it back in, and now I got a good low light image. Is this normal to require a "reboot" to capture extreme light changes? (Clearly, the temperature was not the cause since it was only unplugged for 2 seconds.) Not sure whether the other camera was doing the same thing. May have been running at 11V, but that's within the 12V +- 10% specifications. Anyone seen anything similar? Share this post Link to post Share on other sites

Anyone seen anything similar? not enough power for switch over from day to night. 12v +-10% is from 12v you are using 11v also your amps are more important. get a new power unit 12v 1amp.

videotiger 0 Posted January 29, 2010 Where did you measure 11V, at the power supply or at the camera? Was the camera connected and in night mode when you measured the voltage? The KT&C bullets draw about an amp with the IR LED's on, so you may get significant voltage drop, depending on the length of your power cable run and the gauge of the wire. I have had a camera module (not a KT&C bullet cam) where the IR filter mechanism got stuck with the IR filter out of the optical path. So it's possible for a mechanical problem to happen too.

todd2 0 Posted January 29, 2010 The camera in question doesn't have any IR LEDs. It's one of those lipstick case tiny bullet cams of about 19mm diameter. The night view I mention is because it's an EXVIEW CCD with a spec of .003 lux. 11V at the camera. Share this post Link to post Share on other sites
rory 0 Posted January 29, 2010 Try a different power supply. Those cameras draw very little current so dont need a huge power supply, but it might just be bad. If its in a distributed PSU with other cameras, connect it to a separate PSU and see what happens. Still does it, bad camera. Share this post Link to post Share on other sites
