Motion detection
The motion detection feature delivers the best results with indoor use. You can use the entire image for motion detection analysis or create up to 10 regions for each camera with individually configured sensitivity, Idle timer, and threshold values
- Select Motion detection from the Server side functions menu (you may have to click on the triangle in front of the menu to expand it).
- To activate the motion detection, select Yes from the
drop-down menu.
- If you want to configure a specific region within the image to be used for motion detection analysis, click the plus sign to the right of the camera image. You may change the name of the region.
- Use the polygon tool to draw the region on the camera image. Different sections are only required if you want to monitor each specific section. Use the left mouse button to draw the polygon. Double-click when you return back to the starting point. You can provide unique Sensitivity and Threshold settings to each region.
- Adjust the motion sensitivity as appropriate. The sensitivity value determines how big or small a difference in the image has to be in order to count as motion.
- With a high value, even small changes in the image will be treated as motion.
- With a low value, only big changes in the Image will be treated as motion.
- Increase the value, if you get too many false negative results and decrease it if you get too many false positive results. watch the threshold area. Grey bars will not be recognized as motion. Red bars will. Adjust the Threshold until you achieve the desired results.
- If you use an alarm scenario for motion detection, specify the interval for the Idle timer (in seconds) after which a signal is analysed again. This field is ignored by Record on Motion.

The Activate Filter feature can reduce excess false positives due to environmentally induced motion when using server side motion detection. Examples include: low light scenarios that emit excess noise, places where the light reflection causes noise, etc.
Be aware that this feature is not intended for use on cameras at long distances.
To activate the filter, in the Server side functions > Motion detection screen, set the drop-down under 'Activate Filter' to Yes. Then, we recommend setting the Sensitivity to close to High and Threshold close to Low. As always, we recommend that you review the motion detection settings in different lighting scenarios such as during daylight and night time hours. We also recommend reviewing the recorded video to ensure that only actual motion is being detected and recorded.
- Adjust the Threshold. The threshold determines how big the motion in the images needs to be in order to trigger a alarm.
- Set the threshold to a high value if only big motions are supposed to trigger a alarm.
- Set the threshold to a low value if small motions are supposed to trigger a alarm. The rectangles in the threshold slider window are a visual help for the threshold adjustment. They show the motion amplitude of the last seconds and colors them red, if the current threshold value would have triggered an alarm.
- The colored pixels in the image show where motion was detected.
- A blue colored pixel signifies that motion was detected
- A red colored pixel signifies that a alarm was triggered
As you adjust the sensitivity and threshold settings, and there is motion in the image or selected region, you'll see vertical bars appear in the Threshold section of the screen. When a bar is red, it indicates that motion has been triggered.
- Save the settings.
If you want to record video upon motion, see Record on motion.
