The I/O Terminal Connector
Pinout and Interface
The 4-pin I/O terminal connector provides the interface to:
• 1 transistor output
• 1 digital input
• auxiliary power and GND
The terminal connector is used in applications for e.g. motion detection, event triggering,
time lapse recording, alarm notification via email, image storage to FTP locations, etc.
• Input - for connecting e.g. a pushbutton. If the pushbutton is pressed, the state
changes and the input becomes active (shown under Event Configuration > Port
Status).
• Output - connects e.g. an alarm device that can be activated by Output buttons
on the Live View page, or by an Event Type. The output will show as active
(Event Configuration > Port Status) if the alarm device is activated.

AXIS 207/207W - The I/O Terminal Connector
Description
With a maximum load of 100mA 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 pro-
tection against voltage transients.
Connect to GND to activate, or leave float-
ing (or unconnected) to deactivate.
5VDC/min 2.5W (AXIS 207)
5VDC/min 3.5W (AXIS 207W)
Electrically connected in parallel with the
connector for the PS-L/PS-H power adapter,
this pin provides an auxiliary connector for
mains power to the unit. This pin can also
be used to power auxiliary equipment, max
50mA.
