Setting Tamper Detection
Connected cameras can be configured to detect three types of sabotage detection via the
Video Analytics view (see
Figure 5-8 ): blinding the camera, blurring the video display, and
tampering with the camera field of view. Each setting has three threshold levels: high (80%),
medium (50%), and low (30%). When these thresholds are exceeded, an alarm message
displays on the video display to indicate that a possible camera tampering has occurred
(see
Figure 5-9 ).
When the following conditions are applicable, the tamper detection features must be
manually disabled to avoid raising false alarms:
• During the configuration of the video display
• While text is overlaid on the video
• If the video display becomes too dark
