To assign cameras to alarms, complete the following steps using Figure 18 as a
guide:
1.
Choose an alarm from the Alarm drop-down list. (On DVXi XM sys-
tems, 32 alarms are listed but the Board Alarms are unused.)
2.
Choose up to four cameras that should begin recording when the chosen
alarm is activated. You can choose each camera from the drop-down lists
in the Assigned Cameras area. If you want to choose fewer than four
cameras, leave the remaining boxes on Ignore.
3.
If you choose a camera configured for PTZ on the PTZ tab, you can
select a preset for the camera to pan to if an alarm occurs on the selected
input. To do this, select Activate PTZ Preset and then select a preset num-
ber.
4.
If the alarm is normally in a closed state—that is, if the alarm is triggered
when the circuit is broken—choose Normally Closed. Otherwise, leave
this option unchecked.
5.
Set the maximum duration that the selected cameras should record video
after an alarm trigger. To do this, use the up and down arrows in the
Duration field (the duration is measured in seconds). In Alarm mode,
MasterControl records video until the alarm is returned to its normal state,
or until the maximum duration is reached—whichever occurs first. A
duration of 0 causes recording to proceed until the alarm is returned to its
normal state.
For example, suppose you set the Duration field to 120. If the alarm is
triggered for one minute, MasterControl will record video for only that
minute. However, if the alarm is triggered for an hour (perhaps if a door
or window is left open), MasterControl will record for only the two min-
utes (120 seconds) and then stop. This feature prevents MasterControl
from filling the disk with video long after the actual security breach oc-
curs.
6.
When the alarm is configured properly, click the Activate button.
