A.1 CONNECTING ALARMS
Setting up alarm notifications is covered in Section 4.2 in this manual. This section covers how
to connect alarms to your NVR.
If your NVR features connections for external alarms – both input and output, then it can notify
local users or send notification to a monitoring service when an event is detected. At the same
time, the system can accept signals from motion detectors, smoke detectors or other alarms
and begin recording based on that input and your settings.
You will need to have the manual for your alarm(s) handy to ensure the proper settings within
the NVR.
