Sensor Connection
Our 4 CH DVR system can connect up to four sensors.
There are two steps for sensor installation.
(a) Connect the sensor signal lines to the signal input terminal.
(b) Connect the sensor power lines to the appropriate power source.
In general, there are three different types of sensors available in the home electrics store, where
you can buy them. (1) Normal-Close. (2) Normal-Open. (3) Normal-Close & Open. Below is the
brief diagram about how the each type of sensor is installed into DVR. The procedure for sensor
install action is as shown below.
* After you install sensor(s), change the recording mode as “Sensor record” or “MD & Sensor
record” on “RECORD SCHEDULE” in the DVR menu to enable sensor recording.
* Only the corresponding channel will record when a sensor trips, (e.g. sensor one corresponds
with channel one).
Alarm Connection
The DVR has an internal switch for sounding alarm. The switch is normally open, but when the
sensor is triggered, the alarm is activated as well. The circuitry is as follows.
First, connect the alarm power lines to the alarm switch terminal. Second, connect the alarm
power lines to the appropriate power source.
(1) Normal-Close (2) Normal-Open (3) Normal Close & Open
