Sequential PreAlarm Image Setting
The VPort 16-M12 supports a 9MB memory buffer to record pre-alarm MJPEG images up to 15FPS. This function
configures the frame rate of the MJPEG images being recorded.
Setting Description Default
Max. Frame Rate Configures the maximum pre-alarm frames-per-second to be
logged, either 1, 3, 5, 10, 12, or 15.
10
NOTE
Pre
-
alarm buffers are 9MB in size. So if the maximum frame rate is set to 10, and the video size of each image
is 30KB, then there will be 30 seconds of pre
-alarm MJPEG images recorded: 9000KB/30KB/10=30. If the
maximum frame rate is set to fifteen, then there will be 20 seconds of pre
-alarm images recorded:
9000KB/30KB/15=20.
