VideoEdge NVR 4.1 Release Notes

8200-2735-07 D0

Features

The following features are part of this release:

Video Analytic Rules

Amount of Motion (% of region)

Users can now specify the size of an object to trigger a motion alarm. The size filter is specified

as a percentage (0-100) of region of interest (ROI). Only motion LARGER than the setting will be

successful results. Percentage is computed as the number of grid segments (motion detected in

one segment of a two-segment ROI would be 50% motion). 0% means at least one segment has

motion. 100% means all segments have motion. Motion segments may be disjointed

Duration of Motion (0 to 600 seconds)

Users can specify the amount of continuous motion within a region of interest that is required to

trigger motion alarm. A menu selection box with the ranges from 0 – 600 seconds is selectable.

Zero seconds means any motion that satisfies the motion sensitivity and the amount of motion (if

selected) will trigger a motion alarm.

The V4.1 victor unified client has the above motion parameters available for when a user wants to

perform a search based on motion.

Megapixel Motion Detection Support

As in the V4.01 release, motion detection data can be enabled for high-resolution with the

maximum resolution up to 1280x960.

Server-Side Motion Detection

The specification of motion detection stream is given below:

 Codec: Only MJPEG and MPEG4 are supported. MJPEG is the preferred codec.

 Frame Rate: Video must be at least 4fps. Quality issues may be observed if a lower

fps is used.

 Resolution: For MJPEG streams, the range is minimum QCIF and maximum 4CIF/D1

For MPEG4 streams, the range is minimum QCIF and maximum CIF

The optimal fps/resolution/quality values for motion detection are MJPEG at CIF resolution with

7fps. The following table summarizes the specifications of motion detection streams:

Motion detection runs internally at approximately 7fps. If motion detection utilizes a stream that is

run at a frame rate higher than 7fps, then the motion detection engine will drop frames to make

sure that it is under a certain fps (and CPU load).
