AXIS 212 PTZ/-V Installation Guide
Unit connectors
Network connector - RJ-45 Ethernet connector. Supports Power over Ethernet. Using shielded
cables is recommended.
Power connector - For connection of the PS-H power adapter (included).
Audio in - 3.5mm input for a mono microphone, or for 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).
• Auxiliary power
• GND

Pin Function
4 Transistor
Output
3 Digital
Input
2 3.3V DC
1 GND
Description
With a maximum load of 50mA and a maximum voltage of 24V DC, this output
has 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 protection against voltage
transients.
Connect to GND to activate, or leave floating (or unconnected) to
deactivate.
Can be used to power auxiliary equipment, max 50mA.
