SECTION 3: SETUP CONFIGURATION

To see the output of the tamper detection algorithm on the image, Tamper Debug metadata must be enabled on the VCA >

Advanced menu. Refer to Advanced Settings for more information.

In addition to the Tamper Enable checkbox, the Tamper Detection Settings menu includes three options:

• Tampered Duration until Alarm: The length of time that the image must be persistently changed before the alarm is

triggered.

• Tampered Screen Area: Percentage area of the image which must be changed for tampering to be triggered.

• Suppress alarm on lights on/o: Large changes to the image lighting, such as switching lighting on and o, can cause

false tamper alarms. Enable this option if this condition occurs in the area where the camera is installed. This option will reduce

the sensitivity to real alarms, so it is not recommended for locations where fast light changes are not usually a problem.

False Tamper alarms may occur if the duration and/or screen area are set too low. Adjust the settings so that transient objects close

to the camera do not cause false alarms.

After specifying the tamper detection options for your camera, click Apply.

3.8.4 Burnt-in Annotation

The Burnt-in Annotation setting allows the VCA annotation to be burnt in to the raw video stream. The annotation can include

tracked objects, counters and system messages. The Burnt-in Annotation can be enabled for compressed video streams. To

congure burnt-in annotations for your camera or encoder, go to SETUP > VCA > Burnt-in Annotations
