Motion Detection
117
Table 9-1 Camera Resolutions for Motion Detection
Camera Type Minimum
Resolution
Maximum
Resolution
MJPEG QCIF 1280 x 960
MPEG-4 QCIF CIF
The optimal stream to perform Motion Detection is 32
0 x
240 resolution (or the closest resolution
supported by the camera), MJPEG at 7 frames per second. Lower resolution or framerates might
degrade the quality of Motion Detection. The NVR requires at least QCIF and more than 4 frames
per second to perform motion detection.
Note
Video Analytics run internally at approximately 7fps. If analytics utilizes a stream that is running at
a higher frame rate that 7fps, then the analytics engine will drop frames to make sure that it is
under a certain fps and CPU load.
Procedure 9-1
Enabling Motion Detection for a Camera
Step Action
1 Select Cameras from the main menu.

3 Click Set
up in the camera record for which you want to configure camera settings.
The Function & Streams page opens.

ra Record Status to a setting that supports Motion Detection ( Only
Record on Alarm or
Recording Always with Alarm On).

Note
If an error message opens, the NVR cannot detect a suitable stream from the
camera to support Motion Detection. You will need to change the Codec Image
Resolution, or FPS of one of your camera’s streams to settings that are
compatible with Motion Detection, see Table 9-1.
6 Select the required level of Moti
on Sensitivity. Values range from High (most results) to
Low (least results).
