To configure VMD, you must perform the following steps:
- In the Detection Tools list, highlight a Motion object (1).
- Video motion detection (VMD) recognizes a change in the video signal in relation to a reference image of static background (a specific location , video scene or part of a video scene). For VMD, a block of 80x60 pixels is sampled from the raw image. If the brightness levels of same pixels in the current frame and the background / reference image change and exceed the threshold valiue defined by the Sensitivity: Contrast (7 if sensitivity is at 16 and 29 at the sensitivity threshold value of 0). Motion is detected if the number of brighter / darker pixels exceeds the threshold value defined Sensitivity: Size (3 pixelsfor a 80x60 image with sensitivity values of 10 and 53 pixels at the sensitivity value of 0).
In the viewing tile, set detection zones and/or masks in the same way as for situation analysis detection tools (3).
- Click the Apply button.
VMD configuration is now complete.
