AXIS P3301/P3304 Installation Guide
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 4.0W. See product label for
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 the VAPIX Applica-
tion 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 Event Configuration > Port Sta-
tus) 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).

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
(or 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.
