SENSOR
Sensor In
: Connect the sensors. The sensor are composed of both signal and ground
terminals, with a voltage difference of 5V. In the case that the sensor used for input
is of the N/O (Normal Open) type, when the voltage difference between the signal
and ground falls to 0V (short), the DVR can use this as a trigger to start alarm/sensor
based recording.
Sensor Out
: Connecting external electrical devices
The relay output terminal does not provide power, and functions only on an ON/OFF
basis via a relay. Normally, the signal and ground should be on an OPEN basis, and
the DVR will complete the relay connection.

use HUB, connect cable via hub.
