Audio connector
The Axis product has the following audio connectors:
•
Audio in – 3.5 mm input for a mono microphone, or a line-in mono signal (left channel is used from a stereo signal).
•
Audio out – 3.5 mm output for audio (line level) that can be connected to a public address (PA) system or an active
speaker with a built-in amplifier. A stereo connector must be used for audio out.

I/O connectors
Use the I/O connector with external devices in combination with, for example, tampering alarms, motion detection, event triggering,
and alarm notifications. In addition to the 0 V DC reference point and power (DC output), the I/O connector provides the interface to:
Digital output - For connecting external devices such as relays and LEDs. Connected devices can be activated by the VAPIX®
Application Programming Interface or in the product's webpage.
Digital input - For connecting devices that can toggle between an open and closed circuit, for example PIR sensors, door/window
contacts, and glass break detectors.
