Alarm Connection:
Alarm Input: There is one independent alarm input port (ALM-IN) and one grounding
port(ALM-GND). There are no type requirements for sensors. NO and NC are both
available.
Join the grounding ends of the sensor and the camera and then connect the signal cable
of the sensor to the alarm input port of the camera.
Alarm Output: There is 1 CH alarm output including COM and NO connections.
Loosen the screws in the alarm output port and then insert the signal wires of the alarm
output devices into the port of NO and COM separately. Finally, tighten the screws.
Some of the external alarm output devices need the power supply.
RS 485 Connection:
You can control the speed dome by RS485 interfaces.
