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 in 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.
