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
Event Type. The output will show as active (shown under
Events > Port Status) 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, glass break detectors, etc.
When a signal is received the state changes and the input becomes active (shown under
Events > Port Status).

The following connection diagram gives an example of how to connect an auxiliary device to the
network camera.
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.
Uses an open-drain NFET transistor with the source
connected to GND. If used with an external relay, a
diode must be connected in parallel with the load,
for protection against voltage transients.
