8.4 Alarm Actions
No Alarm Change – 0000 00XXb
If both the start and stop bits are clear, the alarm status and camera record rates will remain
unchanged.
Start Alarm – 0000 01XXb
If only the start bit is set, the DVMRe Pro will enter the Alarm mode. The selected camera will become
the alarm camera. Pre-alarm video will be recorded and the Alarm Record Rate will be initiated.
Every Start Alarm command should subsequently be followed with a Stop Alarm command
at some point. Failure to do so will render that alarm input useless, even if the alarm was
latched and gets acknowledged from the front panel. A Stop Alarm followed by a Start Alarm
will have to be sent to create a new alarm on that channel.
Stop Alarm – 0000 10XXb
If only the stop bit is set, the selected camera’s alarm status will be cleared. If no other alarms are
present, the DVMRe Pro will exit the alarm mode.
Momentary Alarm – 0000 11XXb
If both the start and stop bits are set, a momentary alarm will be initiated on the selected camera. Pre-
alarm video will be recorded at the alarm record rate, after which the DVMRe Pro will continue to
record video at the normal record rate.
