Table 2-1 Rear Panel Connections (Cont’d)
Connector Description
SENSOR IN Connect to external alarm sensor devices to signal the DVR to react to events. Four sensors can be connected to the equipment sensor
Connect two wires to operate a sensor input correctly to the Terminal block on the rear panel of the HRDE4X4. One ground wire between the external device and to the HRDE4X4 ensures the ground reference voltage is identical. This line connects to the terminal block G input. Connect the other wire to be used to trigger the record condition to the sensor input
