Computing The Length Of The Video Archive - Honeywell rapid eye System Administrator Manual

Resetting learning
Reset is enabled when Scene Change is selected. Clicking Reset starts Learning again, and
should be used whenever the camera is moved intentionally to show another scene, or if the
scene's lighting or content changes dramatically. Reset has no effect on Blind and Blur.
Rows of mobile objects
Scene Change is sensitive to large scale changes in a scene. For example, using Scene Change
for a camera that shows many chairs in a row, close by, such as in an airport or casino, may not
be effective. Clicking Reset while people are sitting makes the unit "learn" that sitting persons are
not to be considered as sabotage. When the chairs empty, the scene may have changed enough
for the unit to trigger a log entry or an alarm. And if the operator makes the unit "learn" when the
chairs are empty, then tamper detection may be triggered when people sit in the chairs. The same
can be said for a row of vehicles that are frequently moved, such as in a taxi stand or truck depot.
Alarms
After rearming an alarm produced by the Scene Change-type sabotage detection, move the
camera back to the scene that you need to monitor, and click Reset.

Computing the Length of the Video Archive

Storage Process: Video, Audio, Data
Recordings of video, audio and data are not permanent. When a unit's storage fills, the oldest
recorded video, audio and data are replaced with more recent recordings. The amount of time that
recordings are available is known as the length of the video archive.
What to watch out for
Adding cameras, using high rates, high-resolution and high quality settings for continuous
recording, contribute to shorten the video archive on a unit. High settings in combination, on many
cameras, can shorten a unit's video archive from thousands of days to a few hours. See table 7–7,
p. 128. If a Rapid Eye unit's video archive becomes too short for your needs, try lowering the
resolution and frame rates for continuous recording. How to do so is explained in
Video: Continuous Recording
Scheduling Cameras
Estimates
To make storage estimates, use Honeywell's
Rapid Eye software. To compare and understand the effect of factors on storage, see the tables
for Number of Cameras,
Quality, and Resolution, in the next sections.
Estimate from a unit's statistics
If a Multi System Administrator (Multi SA) only needs to know roughly how far back in time video
can be obtained, data is available when running a Maintenance Session:
Recording tab. "Estimated Storage Capacity" in days, see
Daily Usage Rate. Averaged over the latest 7 days of activity; see the procedure: A Multi-Media
Unit's Storage Statistics, p. 128.
