Note: Update the DVR to the latest version available on the SnapAV Website to use this feature.
8.3.7.1.
MOTION DETECTION
Motion detection allows administrator level users to define how the system responds when motion is detected
for the camera.
1. Select the Motion Detection / Privacy Mask tab.
2. Select the desired camera from the Camera drop-down list.
3. Select Motion from the Type drop-down list.
4. When opened, the area will show Yellow patterns over the camera image (Yellow indicates the areas the
DVR will detect for motion). Click and Hold the left mouse button and drag over the area(s) where motion
detection is not desired.
Tip: Select the entire visible area of the camera to remove motion detection from the camera. After doing so,
select the area in which motion detection is desired.
5. Adjust Sensitivity and Number of grids (number of boxes in the picture that must see motion before triggering)
to achieve the desired results. Adjust Sensitivity and Number of grids for all lighting conditions during setup for
the best results.
6. Select Upload to save the settings.
7. Repeat for all cameras connected to the DVR.
Tips for motion detection setup:
DVRs recognize the change in light to detect motion (this is different than the typical PIR security motion
detector that uses multiple beams of infrared light). It is critical to understand possible changes in the
scene to reduce false motion detection. Generally it is easier to control the lighting and the scene in indoor
environments for accurate motion detection.
However, in exterior locations environmental factors such as shadows due to changes in weather or the position
of the sun, leaves blowing in the wind and even animals can falsely trigger motion detection. For highly
sensitive environments it may be better to use a 3rd party PIR motion detector connected to the alarm inputs
on the DVR. We recommend the use of higher quality cameras (that do not induce noise into the picture in low
light conditions that could false trigger the DVR.
