I/O Connector
Use 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, output
buttons on the Live View page or by an Action Rule. The output will show as active
(shown under System Options > Ports & Devices) if the alarm device is activated.
• Digital input – For connecting devices that can toggle between an open and closed
circuit, for example: PIRs, door/window contacts, glass break detectors, etc. When a
signal is received the state changes and the input becomes active (shown under System
Options > Ports & Devices).
Audio Connector
The Axis product has the following audio connectors:
• Audio in (pink) – 3.5 mm input for a mono microphone, or a line-in mono signal.
• Audio out (green) – 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.
