Connection Module - Axis 231D User Manual

Connection Module

This section describes the pinout provided by the Connection module consisting of:
• 4 transistor outputs
• 4 digital inputs
• power and GND (ground)
The inputs/outputs are used in applications for, e.g. event triggering, time lapse recording,
alarm notification via email, picture storage to FTP locations.
• Input - e.g. a doorbell. If the doorbell is pressed, the state changes, and the input
will be active (shown under Event Configuration | Port Status).
• Output - e.g. an alarm device that can be activated from Output buttons from the
Live View page or as an action to an Event Type. The output will show as active
(under Event Configuration | Port Status), if the alarm device is activated.
