Time-Lapse Recording
The time-lapse feature allows video to be recorded at frame rates that are much
lower than one frame per second (fps). When time-lapse recording is enabled for
a camera, its recorded frame rate is determined by motion detection.
While motion is detected for that camera, its recorded frame rate will be the
normal frame rate currently configured for that camera. (The normal rate is one
of the following NTSC rates: 15.0, 7.5, 3.7, 1.8, 0.9 fps, or one of the following
PAL rates: 12.5, 6.2, 3.1, 1.5, 0.7 fps.)
While no motion is detected for that camera, its recorded frame rate will be the
time-lapse record rate currently configured for the video server. (All cameras on
a particular video server share a single time-lapse recording rate setting. This
setting can be from 1 frame per minute all the way up to 1 frame every 23 days.)
Live video for a camera is not affected by time-lapse recording. It is always
displayed on the client PC at the normal (non-time-lapse) record rate currently
configured for that camera.
