Whether the location of the camera is properly installed, make sure that there is nothing blocking the camera when it rotates left and right up and down (please choose a suitable dome camera according to the camera + lens size) After the self-check, the dome will automatically rotate left and right.

At this time, just use the software or keyboard to control the dome camera to cancel the automatic image flashing or no image.
