In the winter period, if there is no PAN functionality in the camera and despite this, the TILT still works, this could be caused by the snow or ice that might be stuck between the static part of the camera and the moving camera head.
To avoid this, try to increase the preset tour or create an Auto-pan tour to have continuous movement or periodically move (once an hour). The presets will be called via HTTP command, so you have to program an inactivity period to start the last AUX command after a couple of seconds.
This can prevent the camera from freezing again.
A silicone spray applied between the static parts and the camera was NEVER tested and it is not recommended by Bosch
