AXIS P3304-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 amplifier. 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 38. To connect, press and hold the button for about
1 second until the Status LED flashes green.
• Connecting to AXIS Internet Dynamic DNS Service. See page 38. To connect, press and hold the button for
about 3 seconds.
• Resetting the product to factory default settings. See page 44.
Power connector - Mini DC connector
I/O connector
Note
For technical specifications, see page 50.
I/O terminal connector - Use in applications for e.g. motion detection, event triggering, time lapse recording and alarm notifications.
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).
