AXIS P3301-V Fixed Dome Network Camera
Hardware overview
Caution
To protect the product against power surges, a shielded network cable (STP) must be used between the product and the
network switch. Ensure that the network switch is properly grounded.
Audio in (pink) -
3.5 mm input for a mono microphone, or a line-in mono signal (left channel is used from a stereo signal).
Audio out (green) -
3.5 mm output for audio (line level) that can be connected to a public address (PA) system or an active speaker
with a built-in ampli
fi
er. A stereo connector must be used for the audio out.
Control button -
The control button is used for:
• Connecting to an AXIS Video Hosting System service. See
page 34
. To connect, press and hold the button for about
1 second until the Status LED
fl
ashes green.
• Connecting to AXIS Internet Dynamic DNS Service. See
page 34
. To connect, press and hold the button for
about 3 seconds.
• Resetting the product to factory default settings. See
page 40
.
Power connector -
Mini DC connector
I/O connector
Note

.
I/O terminal connector -
Use in applications for e.g. motion detection, event triggering, time lapse recording and alarm noti
fi
cations.
In addition to an auxiliary power and a GND pin, the I/O terminal connector provides the interface to:
•
Digital output
— For connecting external devices such as relays and LEDs. Connected devices can be activated by
the VAPIX® Application Programming Interface, output buttons on the Live View page or by an Action Rule. The
output will show as active (shown under
System Options > Ports & Devices
) if the alarm device is activated.
•
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
System Options > Ports & Devices
).
