ALARM IN
Many QT Series DVRs feature connections for external alarms – both input and output. Please
consult Chapter 2 Connections and Controls to determine whether your model includes
this feature and where the connection block is located. The alarm connector block shown in
Picture 8-1 is only a representation and your actual connector may look different.
When an event is detected the system can notify local users or send notification to a
monitoring service. 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 DVR.
