Unit connectors
Network connector - RJ-45 Ethernet connector. Supports Power over Ethernet. Using
shielded cables is recommended.
Power connector - Mini DC connector. 5.1V DC, max 3.8W. See product label for ±
connection.
Audio in - 3.5mm input for a mono microphone, or a line-in mono signal (left channel is
used from a stereo signal).
Audio out - Audio output (line level) that can be connected to a public address (PA) system
or an active speaker with a built-in amplifier. A pair of headphones can also be attached. A
stereo connector must be used for the audio out.
I/O terminal connector - Used in applications for e.g. motion detection, event triggering,
time lapse recording and alarm notifications. 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 AP, 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
GND 1
3.3V DC
Power
2 Can be used to power auxiliary equipment.
Note: This pin can only be used as power out.
Max load = 50mA
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
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 protection
against voltage transients.
Max load = 50mA
Max voltage = 24V DC
