External I/O Port Definition for the PTZ Internet Camera
The DCS-6620 provides a general I/O terminal block with one digital input and one relay switch for
device control. Pin 1 and pin can be connected to an external sensor and the state of voltage will be
monitored from the initial state ‘LOW’. The relay switch of pin 3 and pin 4 can be used to turn on or off
the external device.
The I/O connector provides the physical interface for digital output (DO) and digital input (DI) that is
used for connecting a diversity of external alarm devices to the PTZ Internet Camera such as IR-Sensors
and alarm relays.
