AXIS F44 Main Unit
I/O Connector
Use with external devices in combination with, for example, tampering
alarms, motion detection, event triggering, time lapse recording and alarm
notifications. In addition to the 0 V DC reference point and power (DC
output), the I/O 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).
Power Connector
2-pin terminal block for power input. Use a Safety Extra Low Voltage
(SELV) compliant limited power source (LPS) with either a rated output
power limited to ≤100 W or a rated output current limited to ≤5 A.
Audio Connector
The Axis product has the following audio connectors:
• Audio in – 3.5 mm input for a mono microphone, or a line-in
mono signal (left channel is used from a stereo signal).
• Audio out – 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 audio out.
