Archive

Archive is a lower-level menu to set up video archival settings:

 “Filter” is a group of archiving options:

 “Save all frames” enables archiving the entire video stream received from the camera.

 “Save all and mark motion” enables saving the entire video stream and marking the frames when motion was detected for future archive browsing.

 “Save only motion” enables archiving only when motion was detected by the on-camera motion detector, and disables it in the absence of motion after a period of time specified under “Continue after motion detected”.

 “Frequency” is a drop-down list of options for archive recording rate. The “Off” option disables the archive recording. The “Max” option sets the archive frequency limited only by the camera and the network (different for different camera models).

 “Continue after motion detected” is a drop- down list of options for the duration of archiving after the motion was last detected by the on-camera motion detector, and the frame rate at which such recording is done. Note: if new motion is detected during such after-motion recording, the rate of recording will revert to the one specified under “Frequency”.

Motion Detection

Motion detection is achieved by analyzing inter-frame brightness changes on a pixel-by-pixel basis. There are two modes of Motion Detection supported in CBC Video System: a software mode and an on-camera mode.

The software mode performs motion detection by processing the images after they were transmitted from the camera to the computer. In contrast, the on-camera mode performs motion detection prior to transmitting the images to the computer. Thus, the on-camera motion detection allows significant reduction in the CPU load and the network load when motion detection is enabled.

Motion detection is enabled via the Archive settings when one of the two following options is selected: “Save all and mark motion” or “Save only motion”. If the Archive is enabled for “Save all frames”
