AXIS Q60 Series
I/O terminal connector - Use with external devices in combination with, for example, tampering
alarms, motion detection, event triggering, time lapse recording 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 > Port & Devices > Port
Status ) if the alarm device is activated.
• Digital input — An alarm 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 > Port & Devices > Port Status ).

DC output 2 Can be used to power auxiliary equipment.
Note: This pin can only be used as power
out. 3.3 V DC
Max load =
250 mA
Digital input – Connect to pin 1 to
activate, or leave floating (unconnected)
to deactivate. 0 to max 40 V DC Configurable

Output)
3–6
Digital output – Connected to pin 1 when
activated, floating (unconnected) when
deactivated. If used with an inductive
load, e.g. a relay, a diode must be
connected in parallel with the load, for
protection against voltage transients. 0 to max 40 V DC,
open drain,
