Attaching A Cable To The I/O Terminal - D-Link DCS-5211L User Manual

Section 2 - Installation

Attaching a cable to the I/O Terminal.

The 4-pin I/O connector is located at the rear
panel and provides an interface for photo-
coupled switch output and photo-coupled
input. An example of what can be done
with a digital input and digital output is the
connecting of a motion sensor to the port,
signalling the camera to take a snapshot
and trigger an alarm connected to the port.*
