AXIS Q1775 Network Camera
Technical specifications
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).

Digital input – Connect to pin 1 to activate, or leave floating
(unconnected) to deactivate.
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.
