AXIS 211W - I/O Terminal Connector

I/O Terminal Connector

The I/O terminal connector is used in applications such as 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. 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).

•Auxiliary power and GND
