SEQUENCE DWELL time.
Some alarming devices (such as some motion detectors)
generate very brief alarms lasting only a fraction of a
second. The “Hold Detected Alarms for” time is the amount
of time that the alarm event will be held so that the alarm
camera image can be kept on the display screen and
mutiplexed at a high frame rate to the VCR.
The maximum time for holding an alarm display set in the “Disable Detected Alarms after” option will
determine how long a continuous alarm camera will be displayed. This can be adjusted so that a
continuous alarm will not consume all of the VCR’s record time. A value of zero (factory default) will
result in no time limit for an alarm display.
The “Hold Alarmed Images for” time determines the image display hold time during multi-camera
alarms. When multiple alarms occur simultaneously, the monitor display will sequence between all
cameras with alarms using this dwell time. Every alarming camera will be multiplexed to the VCR at a
high priority “alarm” frame rate.
Both delay times are adjustable from 1 to 255 seconds though the default is 1 second for the
activation hold and 3 seconds for the sequence dwell time. Camera buttons are used to enter digits 1
through 9 and the PIP button is used to enter 0. The DISPLAY button stops the editing of a delay
value.
