Enable Video Intelligence for a Camera

To enable a camera to use Video Intelligence features, you can use the Video List Page or the

Function and Stream settings section of the camera Advanced Edit page.

Figure 10-1 Function and Stream Settings

You must ensure you have a Stream Specification that allows the NVR to generate meta-data for

Video Intelligence. You also need to select Video Intelligence in the Video Analysis field.

The NVR will automatically determine the required settings and apply

them to a stream. If the

camera is configured for dual-stream, then the NVR chooses the best stream. If the NVR is unable

to find a suitable video stream for Video Intelligence an error message opens.

Video intelligence may not be available for a particular ca

mera if the camera’s video resolution

setting is lower than the minimum or higher than the maximum acceptable resolution for Video

Intelligence. The NVR will not allow you to configure a camera for Video Intelligence if the

resolution setting of the camera is outside of the settings in Table 10-1.

Table 10-1 Camera Resolutions for Video Intelligence

Camera Type Minimum

Resolution

Maximum

Resolution

MJPEG 320 x 180 1280 x 960

MPEG-4 320 x 180 CIF

The optimal stream to perform Video Intelligence is CIF (320 x 240 resolution) MJPEG at 7 frames

per second. The NVR requires at least 320 x 180 resolution and more than 4 frames per second to

perform Video Intelligence activities.

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.
