Network Camera provides a very flexible general I/O interface to combine with the user's
security devices such as sensors, alarms, lighting or door locks. The general I/O terminal
block has six pins for device control. These pins can be divided into two categories based on
their functions, including RS485 and digital inputs and outputs.
If the device connected to COM has an RS485 interface, wire two control lines to pin 5 and
pin 6. After switching to RS485 on the configuration page, the PT control commands will be
directed through pin 5 and pin 6. If the distance from the controlled device is too far to
allow accurate function, an external power source may be used to pull high the RS485
signal.
Network Camera provides one digital input and one relay switch. Pin 1 and pin 2 can be
connected to external sensor and the state of voltage will be monitored according to the
programmed scripts in configuration. The relay switch can be used to turn on or off external
devices.
