Compare images
Tamper Detect compares the current scene with all available reference images. If a match is
found a green crosshair is superimposed on the image in the Feedback view. Information about
the matched image and the match level is displayed under the Feedback view.
The small green circle in the middle of the image indicates the amount of camera movement that
is allowed. A position alarm is raised when the green circle is outside the crosshair centre. For
information about adjusting the amount of allowed camera movement, see Position
Measurement.
If no match is found a BLOCKED OR CHANGED SCENE alarm is raised.
Current image matches Reference 1
Reference image(s) available. No match found
with current image, though.
The drop-down list in the Feedback View section can be used to display the current image, the
best matching reference image, or a specific reference image.
