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.

Connect to GND to activate, or leave floating (unconnected)
to deactivate.
4
Internal connection to ground when activated, floating
(unconnected) when deactivated. If used with an inductive
load, e.g. a relay, a diode must be connected in parallel with
the load, for protection against voltage transients.
