Answer:

Some IP cameras support CVBS output, please go to Configuration – Image – Display settings – Other - Local Output to enable it.

Answer:

Possible reasons and solutions: Unmatched lens mount. There are two types of lens mount for box cameras,respectively are CS mount and C mount, the lens and camera must be matched with the same type. Use Focus in / focus out to control the Clarity. Check whether the lens or housing gets dirty. In case of strong light condition, please select electronic iris as the lens type.

Answer:

Lack of power supply might cause phenomena as below: ICR switches frequently The camera’s image looks dark Some ripples appear in the image. The camera might reboot frequently

Answer:

It’s caused by low color temperature.

Answer:

The light is strong at day-time and the iris is small, the depth of filed becomes larger after focalizing. However, the iris becomes larger in the evening due to weak light and the depth of filed becomes smaller,leading to the object being monitored falling out of the depth of filed. The solution is that, please kindly set the camera to electronic shutter mode when trying to focalize using automatic iris lens (the automatic iris would be the largest), then change back to automatic iris mode. Or try to focalize under low illumination condition.
