Media > Image
You can use the following methods to activate the camera with its backup firmware:
1. Press and hold down the reset button for at least 1 minute.
2. Power on the camera until the red LED blinks rapidly.
3. After boot up, the firmware should return to the previous version before the camera hung. (The
procedure should take 5 to 10 minutes, longer than the normal boot-up process.) When this process is
completed, the LED status should return to normal.

This section explains how to configure the image settings of the camera. It includes the following tabs:
General settings, IR Control, Image Settings, Exposure, Focus, and Privacy mask. The Focus tab is
