Reference image comparison
The live camera image is compared to a defined reference image of the same camera view (see Manual reference image comparison). An alarm will be triggered if the images
do not match and triggers a second alarm when the original camera view is restored.
- Select Reference image comparison in the server side operation menu.
- To activate the automatic image reference comparison, select Yes
from the drop-down-menu.
- Click Create reference image to select an image from the camera that serves as a backdrop for the motion detection.
- Select Show differences only to show only the differences between the live-image and the reference image.
- Adjust the Alert threshold (tolerance) in percent. An alarm will b e triggered only if the differences between the live image and reference image are above the threshold.
- Specify the values for the Execution time point by defining the time interval (in minutes, at a certain day time or on certain days per week at a specific time) for the comparison between the reference image and the live image.
