How to fix the position of a mobile camera? It always returns to its original position.

Does your network camera have a pan/tilt that can be rotated? If it automatically corrects this setting problem, like Shenzhen Schnei'an's network PTZ camera, you can set a pre-support point. When the camera is powered off and restarted, it will automatically return to the position of the pre-support point. This prevents malicious damage from people. If you don't have a PTZ, then It means your bracket is not fixed properly
