lapse recording and alarm notifications. It provides the interface to: 

• 1 transistor output - For connecting external devices such as relays and LEDs. Con-

nected devices can be activated by AXIS VAPIX AP, output buttons on the Live View 
page or by an Event Type. The output will show as active (shown under Event Config-
uration > 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).

Can be used as an alternative power supply (7-20VDC) or to power 
auxiliary equipment  +5VDC (100mA).

Max load = 100mA

Connect to GND to activate, or leave floating (or unconnected) to 
deactivate.

Must not be exposed to voltages greater 
than

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 protection against voltage 
transients.
