I/O terminal connector - Used in applications for e.g. motion
detection, event triggering, time lapse recording and alarm
notifications. In addition to an auxiliary power and a GND pin, it
provides the interface to:
• 1 digital output – For connecting external devices
such as relays and LEDs. Connected devices can be
activated by the VAPIX® Application Programming
Interface (API), by the 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.
• 1 digital input – An alarm input for connecting devices that can toggle between an
open and closed circuit, for example: PIRs, door/window contacts, and glass break
detectors. When a signal is received the state changes and the input becomes active
(shown under System Options > Ports & Devices).

Notes
Ground
Can be used to power auxiliary equipment.
Note: This pin can only be used as power out.
Connect to GND to activate, or leave floating
(unconnected) to deactivate.
Internal connection to ground when activated,
floating (unconnected) when deactivated. If used
with an inductive load, eg. a relay, a diode must be
connected in parallel with the load, for protection
against voltage transients.
