AXIS 207/207W - The I/O Terminal Connector
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.
Function  Pin Description Pinouts
Transistor 
Output
4 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.
The I/O terminal pins on the 
AXIS 207 and AXIS 207W are

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.
