Alarm Operations
Live Filter Events
The Intellex live filters enable the unit to respond to specific activity
at specific cameras. When configured, these filters help the unit
record important activity and ignore unimportant activity.
A live filter event occurs when the live filter is triggered by some
activity in the camera’s field of view.
When the unit detects a live filter event:
1. The unit energizes the alarm output associated with the
camera.
2. The unit records images from the alarm camera at the alarm
record rate and quality setting (see Alarms Setup on page 78).
3. The unit adds the alarm camera to the alarm group and
records its images more often than nonalarm cameras (see
Alarm Groups on page 147).
4. The unit lights the Alarms indicator as soon as the alarm is
cleared.
5. The unit flags the video segment in the image database with
the name of the live filter.
6. If the Pre-Alarm Duration option is selected, the unit saves
the pre-alarm images to the image database (see Custom
Schedule Setup on page 50).
7. If the Alarm Message Display option is selected (see Alarms
Setup on page 78):
a. If the camera is not currently displayed or is displayed in the
camera sequencing window, the unit switches the live
display monitor to the 4x4 format and overrides the display
settings for the duration of the alarm (see Display Setup on
page 82).
b. The unit displays ALARM over the camera image.
c. If the Latch Messages option is selected (see Alarms Setup
on page 78), the unit enables the Clear Latched button on
the Utility Options screen (see Utility Options on page 105).
d. The unit suspends camera sequencing on the live display
monitor.
