Camera Tampering Detection - Abus TVIP41550 Manuel Utilisateur

Functionality of motion detection:
A
B
Two parameters are available for configuring motion detection: Sensitivity and percentage. The figure
shows how these two parameters influence motion detection.
A motion occurs, shown in the progression from figure A to figure B. The resulting pixel changes (depending
on the sensitivity setting) are shown in figure C (grey). The "Sensitivity" setting refers to the capacity of the
sensor to detect motion in the picture. The higher the set value, the more pixel changes are detected in the
picture. When motion is detected, the pixel changes (depending on the sensitivity setting) are saved on the
server as alarm pixels (pink areas in figure D). The "Percentage" value describes the percentage of the
"alarm pixels" in relation to the total number of pixels in the selected area. If the specified percentage of alarm
pixels is reached or exceeded, an alarm is triggered. To ensure reliable motor detection, a high sensitivity
setting and low percentage value is recommended.
Working with profiles
Click on the "Profile" button to assign the motion detection to an explicit day or night profile. A new window
opens in which you can assign the motion setting to a profile.
You must mark the "Enable this profile" button to activate the profile mode. When you create a motion
window, you can now assign the profile day mode or night mode to it. Up to 3 windows can be assigned per
profile. Depending on the day/night mode of the camera (see audio and video settings), you can make
settings in guard mode with differing sensitivities for video verification according to the time of day. If no profile
is used, the motion setting is used regardless of day/night mode.

12. Camera tampering detection

The video server supports tampering detection. If detection is enabled, the alarm can be used as an event for
a notification (see "Application").
