AXIS Q8685-E PTZ Network CameraI/O connectorUse 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 (DCoutput), the I/O connector provides the interface to:Digital input - For connecting devices that can toggle between an open and closed circuit, forexample PIR sensors, door/window contacts, and glass break detectors.Digital output - For connecting external devices such as relays and LEDs. Connected devices canbe 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 lightsensor. This is used to control the product’s day and night functionality.6-pin configurable terminal blockFunction Pin Notes SpecificationsDC ground 1 0 V DCDC output 2 Can be used to power auxiliary equipment.Note: This pin can only be used as power out.12 V DCMax load = 50 mADigital input – Connect to pin 1 to activate, orleave floating (unconnected) to deactivate.0 to max 30 V DCConfigurable(Input orOutput)3–6Digital output – Internally connected to pin 1 (DCground) 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.0 to max 30 V DC,open drain, 100 mAExample50
