I/O terminal connector - Used in applications for e.g. motion detection, event triggering,
time lapse recording, alarm notifications, etc. It provides the interface to:
• 1 transistor output - For connecting external devices such as relays and LEDs.
Connected devices can be activated by AXIS VAPIX API, output buttons on the
Live View page or by an Event Type. The output will show as active (shown
under Event Configuration > 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 Event Configuration > Port Status).
• Auxiliary power and GND.
Function Pin number Notes Specifications
Transistor
Output
4 Uses an open-collector NPN transistor with
the emitter connected to the GND pin. If used
with an external relay, a diode must be con-
nected in parallel with the load, for protec-
tion against voltage transients.
Max load = 50mA
Max voltage = 24V DC
(to the transistor)
Digital Input 3 Connect to GND to activate, or leave floating
(or unconnected) to deactivate.
Must not be exposed to
voltages greater than
10V DC
7 - 20 V DC
Power
2 Can be used to power auxiliary equipment. Max load = 50mA
