How do I use the Digital I/O function of the camera?

The Network Camera provides a general I/O terminal block with one digital input and one relay switch for device control. Pin 3 and Pin 4 can be connected to an external sensor device and the state of voltage can be monitored from the initial state 'LOW'. The relay switches Pin 1 and Pin 2 can be used to turn on or off an external device.
