Alarm Input Wiring

In this example, we are going to use the iDVR-PRO8H which has 8 alarm inputs. The below wiring diagram shows how to connect a magnetic door sensor to alarm input one on the DVR. One of the wires from the door sensor is connected to the port labeled input 1. The other wire from the sensor is connected to the ground.

On the alarm sensor event screen, double-click on the name field for the input number that you are configuring to name the alarm. In the operation field, choose whether the normal state for this sensor is normally open (N/O) or normally closed (N/C). A door sensor, for example, is normally closed. When the door is opened, the magnetic charge is no longer present and the circuit is opened. In the linked camera field, click the drop-down and select one or more cameras that you want to be associated with this alarm. The alarm output setting is optionally used if you want the alarm to trigger an output sensor.
