2-5 Digital I/O Connector Block LED Status Indicator
Chapter 2: Product Overview
Digital I/O Connector Block
The I/O connector on the back of the camera provides a central interface between your home security system
and various output devices.
The two digital inputs are normally used with security sensors, e.g. passive infrared sensors (PIR), smoke
detectors, door/window sensors, etc. They work by detecting a change in the state of open and closed circuit.
You can check the status of the circuit in [Setup] > [Event Setup] > [I/O Status].
The output port is normally used to trigger external audio or visual indicators, e.g. sirens or strobe lights, etc.
