To define defocus detection:
1. From the menu toolbar, click Configuration > Events > Defocus Detection.
2. Check the Enable Defocus Detection checkbox to enable the function.
Sensitivity: The range is between 1 and 100. The higher the sensitivity level, the
smaller the defocus required to trigger an alarm.

methods for the system when a defocus detection alarm is triggered.

software when an event occurs.

option. See “To set up the email parameters” on page 16 for
further information. If you want to send the event snapshot
together with the email, check the Attached Snapshot option.

Scene change detection
You can configure the camera to trigger an alarm when the camera detects a change in
the scene caused by an intentional rotation of the camera.
