Alarm settings
This chapter describes setting up how the system will respond when an alarm is
triggered.
Description of alarm notification types
When setting up the rules for alarm detection, you can specify how you want the
NVR to notify you about an alarm or event. You can select more than one
notification type. Not all notifications types are available for all types of alarms.
The alarm notification types are:
• Audible warning: Triggers an audible beep when a notification or alarm is
detected by the system or a camera.
• Notify surveillance center: Sends a signal to TruVision Navigator or other
software applications when an alarm or notification is detected.
• Send e-mail: Sends an e-mail when an alarm or notification is detected. See
“Configuring e-mail” on page 103 for information on how to configure the NVR
to send an e-mail.
• Trigger alarm output: Triggers an alarm output when a notification is
detected for an external alarm. See “Setting up external alarms” on page 94
for information on configuring an alarm output.
Setting up motion detection
Motion detection is one of the most important features of a NVR. With it there is
no need to manually search through hours of video recordings to find an event.
The NVR can be set up to trigger an alarm if it detects motion and to record it.
You can then search these recorded motion activities for specific incidents. If
enabled, motion detection recording can help increase the number of days your
NVR can record.
You can mask out any areas of motion on an IP camera display that you do not
want to trigger a recording such as a flag on a pole or a moving tree.
