Enable the Camera Integrity Monitor module.
Before you begin
What you should know
- Camera integrity monitoring can support PTZ cameras that are used as fixed cameras.
- If you change the position of a camera, you must reset the integrity monitoring feature on the camera so that the Camera Integrity Monitor can recalculate what is considered to be the 'normal' camera view.
- From the Config Tool home page, open the Area view task.
- Select a camera to configure.
(Optional) Create a camera thumbnail.
The camera thumbnail is a reference image that the maintenance technician can use to reset the camera to its original position when they fix a camera tampering issue. It is not used by the system for integrity monitoring.NOTE: You can only create or update the thumbnail if the Encryption in transit and at rest option is enabled for your camera on the camera Recording page.

- In the thumbnail area, click Play ().
Click Update thumbnail ().
- Click Apply.
