The RS485 connector can be used to control Pan / Tilt / Zoom (PTZ) cameras.
See the PTZ camera manufacturer’s manual for configuring the RS485
connection.
Note Use the RS485 connector for external control systems such as a
control keyboard. Connect RX-/TX- and RX+/TX+ of the control
system to the TX-/RX- and TX+/RX+ (respectively) of the DVR.

block from the DVR for easy access. Use a small screw driver to open the
connection and insert the wire into the hole. To disconnect the wire loosen the

Mechanical or electrical switches can be wired to the Alarm In and Ground

Note All connectors marked GND are common. Connect the ground side
of the alarm input and/or alarm output to the GND connector.
Connecting to a Relay Output
