Unit connectors

Antenna connector - Reverse SMA connector for antenna.
Network connector - RJ-45 Ethernet connector. Supports Power over Ethernet. Using
shielded cables is recommended.
Power connector - Mini DC connector. 7 - 20V DC, max 5W. 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 connect-
ing 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 Configura-
tion > Port Status).
• Auxiliary power and GND

Notes
Ground
Can be used to power auxiliary equipment
(7-20VDC) or as a +5VDC (100mA) output.
Connect to GND to activate, or leave float-
ing (or unconnected) to deactivate.
Uses an open-collector NPN transistor with
the emitter connected to the GND pin. If
used with an external relay, a diode must be
connected in parallel with the load, for pro-
tection against voltage transients.
