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
±
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 the VAPIX Application Programming Interface (API), by the out-
put 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 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
).

Connect to GND to activate, or leave floating
(or unconnected) to deactivate.
Min. input= - 40V DC

Output
4
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.
Max. load = 100mA
Max voltage = + 40V DC
