AXIS Q8685-LE PTZ Network Camera
I/O connector
Use the I/O connector with external devices in combination with, for example, 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 input - For connecting devices that can toggle between an open and closed circuit, for
example PIR sensors, door/window contacts, and glass break detectors.
Digital output - For connecting external devices such as relays and LEDs. Connected devices can
be activated by the VAPIX® Application Programming Interface or from the product's webpage.
A digital light sensor - For receiving a value of the ambient light intensity from an external light
sensor. This is used to control the product's day and night functionality.

Notes
Can be used to power auxiliary equipment.
Note: This pin can only be used as power out.
Digital input – Connect to pin 1 to activate, or
leave floating (unconnected) to deactivate.
Digital output – Internally connected to pin 1 (DC
ground) when active, and floating (unconnected)
when inactive. If used with an inductive load, e.g.,
a relay, connect a diode in parallel with the load,
to protect against voltage transients.
