This statistics page gives the operating system version number as well as the
recording statistics based on the last minute of recording. The recording
statistics are updated every minute and are intended to be used for monitoring
a camera system and to provide an indication of the capacity of the
OmniBase in different recording environments.
The kbytes/min entry indicates how many thousand bytes have been recorded
in the most recent minute
The Mbytes disk free entry indicates how many Megabytes of disk space are
free for loop recording. If there are no alarm recordings this figure will be
constant and indicate the size of the hard disk. With write-protected alarm
recordings the free space goes down.
The number of images recorded in the last minute is indicated.
The kbytes/image average is produced by dividing kbytes/min by
images/min.
of motion images. This is especially significant in 168 /
480 / 960 hour modes.
10 minutes; Difficult to find footage because start points every 10
minutes, BUT efficient on disk usage as full images are
infrequent.
A keyframe rate is automatically provided when the user edits the
NORMAL MENU
. The rate is calculated as the nearest setting to (no. of
recorded cameras) * (hours recording) ÷ 200.
ORDER
- This determines the order in which images are grabbed from the
cameras. During recording LED flashes show the camera sequence to the
operator. Use the buttons numbered
to include cameras, and the
&'.'6'
button to remove them from the list.

Motion format:
High Motion
Pedestrian precinct, very busy office, scenes with
continuous motion. 50% screen update so image sizes are
50% of full format recording.
Medium Motion Bank, office, warehouse with activity, factories retail
premises, busy car parks, storage handling areas. 15%
screen update so image sizes are 15% of full format
recording
Low Motion
Small car park, quiet entrance hall, warehouse with
infrequent activity, small office, private home. 8% screen
update so image sizes are 8% of full format recording.
Dividing the available disk space by a figure in the previous table gives the
