Unit connectors
Network connector -
Power connector - Mini DC connector.
Audio in - 3.5mm input for a mono microphone, or a
Audio out - Audio output (line level) that can be connected to a public address (PA) system or an active speaker with a
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 exter- nal 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 out- put will show as active (shown under Event Configuration > Port Status) if the alarm device is activated.

Terminal connector. Note that the pins are numbered
•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).
