Viewing a camera tamper alarm
You can setup the system to alert you when someone has deliberately blocked a camera view,
such as by spraying paint on the lens (also known as anti-masking). You can set it up so that a
specific part of the screen can detect a tamper and thereby trigger an alarm. You can also setup
how the system will alert you to the tamper alarm. You can only setup one anti-masking area on
screen.
