Configuration
Tamper Detection
With tamper detection, the camera is capable of detecting incidents such as
redirection, blocking or de-focusing, or even spray paint.
To enable tamper detection, follow the steps given below:
1. Select
Enable camera tampering detection
.
2. Enter the tamper trigger duration (10 sec. ~ 10 min.). The tamper alarm will
be triggered only when the tampering factor (the difference between current
frame and pre-saved background) exceeds the trigger threshold.
Set up the event source as Camera Tampering Detection on Event Settings > Server
Settings (how to send alarm message)/ Media Settings (send what type of alarm
message)/Event Settings/. Please refer to Event settings for detailed information.
