Network connector -  RJ-45 Ethernet connector. Supports Power over Ethernet. Using 
shielded cables is recommended.

Power connector - Mini DC connector. 5.1V DC, max 3.6W. 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, alarm notifications, etc. It provides the interface to: 

• 1 transistor output - For connecting external devices such as relays and LED:s. 

Connected devices can be activated by Output buttons on the Live View page or 
by an Event Type. The output will show as active (shown under Event Configu-
ration > 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).

• Auxiliary power and GND

Transistor 
Output

4

Uses an open-collector NPN transistor with 
the emitter connected to the GND pin. If 
used with an external relay, a diode must be 
connected in parallel with the load, for pro-
tection against voltage transients.

Max load = 50mA
Max voltage = 24V DC 
(to the transistor)

Connect to GND to activate, or leave float-
ing (or unconnected) to deactivate.

Must not be exposed to 
voltages greater than 
10V DC
