2.2.5.3 Sabotage Detection

The Camera Sabotage behavior detects scene changes or contrast changes in the field of view. An event or alarm is triggered if

the lens is obstructed by spray paint, a cloth, or if it is covered with a lens cap. Any unauthorized repositioning of the camera

also triggers an event or alarm.

Scene Setup for Camera Sabotage

Install the camera in a high position, looking down on the scene. The field of view should be as large as possible. A small field of

view could result in the view being blocked by an adjacent object.

Avoid scenes with a dark, uniform background, low lighting, and large moving objects.

Sabotage Detection

1. Check Enabled button to enable Sabotage Detection.

2. Configure the settings:

 Sensitivity: Determines the triggering sensitivity for alarm. High sensitivity is triggered most easily but is prone

to more false alarms. Low sensitivity will only trigger an alarm for major issues like blackout.

 Event logging (Profile) name: Type a user-defined string name that will display within an alarm event to help

users to easily distinguish among cameras.

 Alarm Severity: Defines the severity of an alarm to allow the prioritization of alarms.

2.2.5.4 Audio Detection

This function is designed to define the audio intensity threshold for triggering an alarm from surrounding audio. Check to enable

this function. With an external mic connected, a waveform representing the level of audio intensity will be displayed in the box.

Under Sound Intensity Threshold, adjust the threshold bar or input a number (from 0 to 100) in the box right above it for the

desired threshold level. A horizontal line, which indicates the exact threshold, in the box underneath will move up or down

accordingly.
