AXIS 210/210A/211/211A Installation Guide Page 15

I/O terminal connector - Used in applications for e.g. motion detection, event triggering, time lapse recording, alarm notifications, etc. It provides the interface to:

• 1 transistor output - For connecting external devices such as relays and LEDs. Connected devices can be activated by AXIS VAPIX API, output buttons on the Live View page or by an Event Type. The output will show as active (shown under Event Configuration > 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. ENGLISH
