Sensor Installation
There are a total of 4 sensor input terminals located in the rear of the DVR. The
sensor input is use to setup hard wire external sensor such as motion sensor,
window/door sensor, and etc. Since the terminal does not provide power to
the input devices, the sensor is required to have its own power. There are two
simple steps to install hard wired sensor input as follow:
• Choose one of the four terminals to connect the sensor into. Connect
the sensor signal lines to the SENSOR input terminal as shown in the
picture diagram below.
• If the sensor requires power, use the power from the sensor device, plug
the power jack into the sensor and then plug the other end of the power
adapter to an electrical outlet.
Generally, there are three different types of sensor configurations: Normally
Close, Normally Open, and Normally Close & Open (N/A). For LCDDVR4 only
two of the three configurations used; Normally Close, Normally Open, or None
(default setting). Most commonly used is the Normally Open relay. Below are
general diagrams of the different sensors relay and how they are installed in
conjunction to the LCDDVR4 terminals:
Note: Most input may not require power. Each sensor input terminal corresponds to
the actual camera channel. For example; Sensor #1 interacts with channel #1
camera, sensor #2 corresponds with channel #2 camera and so on
