2.9 Adjusting Motion Detection Sensitivity
If using the motion detection feature to buffer or transfer camera images, you may want to adjust the motion detection sensitivity for optimal results.
1.
Click the [Setup] tab.
2.
On the left side of the screen under [Buffer/Transfer], click [Motion Detection].
3.
Observe the [Preview] area to confirm how the current settings detect motion.
Any changes you make on this page will not be reflected in the [Preview] area until you click [Save].
4.
If necessary, adjust the detection threshold by clicking the appropriate block.
5.
If necessary, adjust the motion sensitivity by clicking the appropriate block.
6.
Click [Save], and then click [Go to Motion Detection page].
7.
Observe the [Preview] area to confirm how the new settings detect motion, and repeat from step 4 if necessary.
Understanding [Threshold] and [Sensitivity]
Motion detection threshold and sensitivity can be adjusted. Understanding how threshold and sensitivity interact will help you adjust the motion detection feature to suit your needs.
[Threshold]: Determines at what point the motion detection feature is triggered. A lower threshold means less motion is needed to trigger the motion detection feature. A higher threshold means more motion is needed to trigger the motion detection feature. Threshold is indicated in the [Preview] area by the light green area.
[Sensitivity]: Determines how easily the camera detects motion. Lower sensitivity means the camera is less likely to detect motion. Higher sensitivity means the camera is more likely to detect motion. Motion is indicated in the [Preview] area in dark green when it has not exceeded the detection threshold, and is indicated in dark red when it has exceeded the detection threshold.
[Preview]: Refer to this area to see how the current settings (effective after clicking [Save]) detect motion.
The following examples show how [Threshold] and [Sensitivity] are represented in the [Preview] area.

[Preview]
High threshold (A), high motion (D), motion detection is triggered
Note
Motion is detected by changes in the outline of objects and changes in object brightness, however, in some cases the camera may detect rapid brightness changes by artificial light sources (such as fluorescent lights) as motion.
The camera’s motion detection feature detects motion differently than the Network Camera Recorder software (sold separately).
Motion may not be detected as desired if the object’s color is similar to the color of the background.
Motion detection can vary by the object, image resolution, or image quality. Refer to the [Preview] area to see how the current settings detect motion.
