6.2.5 Alarm setup
This menu is used to set up the actions to be taken if an alarm is detected. Possible alarms
are:
•
Motion detection.
•
Videoloss (on one or more input channels)
•
External alarm (alarm arising from closure/opening of one or more of the contacts on
the alarm terminal board).
BUZZER DWELL: sets the length of time for which the buzzer will sound if the alarm is
triggered (from 1 to 30 seconds).
VIDEOLOSS ALARM: enables/disables the alarm for input video loss.
MOTION ALARM: enables/disables the alarm for motion detection.
EXTERNAL ALARM: enables/disables the external alarm (coming from the contacts on the
terminal board at the back of the device).
Starting from the title [RELAY], the three subsequent items refer to activation of the relay in
specific cases:
VIDEOLOSS ALARM: triggering/non triggering of the relay in the case of an alarm of the
type “VIDEOLOSS ALARM”.
MOTION ALARM: triggering/non triggering of the relay in the case of an alarm of the type
“MOTION ALARM”.
EXTERNAL ALARM: triggering/non triggering of the relay in the case of an alarm of the type
“EXTERNAL ALARM”.
EXTERNAL SENSOR SETUP: setting for the type of contact of the external alarm. The
contact can be selected as “normally open” or “normally closed” i.e. setting the alarm to
trigger when the contact between alarm input and the “GND” terminal closes or opens
respectively.
ALARM DISPLAY MODE:
if in “MUX” recording mode, whatever the normal display
setting, if an alarm is triggered the DVR will display the video corresponding to
the alarm on full screen.
