AXIS P1343-E Network Camera
Hardware overview
I/O terminal connector - Use in applications for e.g. motion detection, event triggering, time lapse recording and alarm notifications. In addition to an auxiliary power and a GND pin, the I/O terminal connector provides the interface to:
•Digital output — For connecting external devices such as relays and LEDs. Connected devices can be activated by the VAPIX® Application Programming Interface, output buttons on the Live View page or by an Action Rule. The output will show as active (shown under System Options > Ports & Devices) if the alarm device is activated.
•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 System Options > Ports & Devices).
Note
The I/O connector is connected to the housing (fan/heater) on delivery, and will trigger an input port event to indicate a fan or heater error when activated. See Events, on page 35 for information on how to set up an event.
