Fine-tuning the sensor
If you are having trouble identifying the source of motion in your video, you may experiment with the
Highlight motion feature. This will cause each image to be overlaid with a representation of the motion in that image. That is, what's changed from one frame to the next will be shown with a blue or green overlay, depending on whether the change is either internally positive or negative. If using the Object detect/reject feature, you may also select to show the object rectangles.
Another way to "see" what the software is detecting as motion is to open a recorded video in the viewer window, then right-click to select the
Test run video through motion detector option. To use this feature, the video must meet these requirements:
- The video must be BVR format.
The camera which recorded the video should still exist
- The video must begin with several seconds of video prior to the point of interest.
- The video should not have been recorded with the highlight motion option enabled.
When you play the video it will pass through the motion detector using the settings for the camera which recorded it, with the addition of the highlighting feature to show motion and objects. In addition, portions of the frame which are masked out (not part of any zone) will be shaded.
Don't forget to turn off the
Test run video through motion detector option when you are finished.
