Analysis type
Select the required analysis algorithm. Motion+ offers a motion
detector and essential recognition of tampering.
Metadata is always created for a video content analysis, unless
this is explicitly excluded. Depending on the analysis type
selected and the relevant configuration, additional information
overlays the video image in the preview window next to the
parameter settings. With the Motion+ analysis type, for example,
the sensor fields in which motion is recorded are marked with
rectangles.
Click Configuration to set up the analysis type.

Tamper detection
Detect tampering of cameras and video cables by means of
various options. Run a series of tests at different times of the
day and night to ensure that the video sensor is operating as
intended.
Sensitivity and Trigger delay [s] can only be changed if
Reference check is selected.
Reference check
Save a reference image that can be continuously compared with
the current video image. If the current video image in the
marked areas differs from the reference image, an alarm is
triggered. This detects tampering that would otherwise not be
detected, for example, if the camera is turned.
