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.

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, a diode must be connected in parallel
with the load, for protection against voltage transients.
