AXIS P1455–LE-3 License Plate Verifier Kit
Specifications
I/O connector
Use the I/O connector with external devices in combination with, for example, motion detection, event triggering, and alarm
notifications. In addition to the 0 V DC reference point and power (DC output), the I/O connector provides the interface to:
Digital input - For connecting devices that can toggle between an open and closed circuit, for example PIR sensors, door/window
contacts, and glass break detectors.
Digital output - For connecting external devices such as relays and LEDs. Connected devices can be activated by the VAPIX®
Application Programming Interface, trough an event or from the product's webpage.

Can be used to power auxiliary equipment.
Note: This pin can only be used as power out.
3
Connect to pin 1 to activate, or leave floating (unconnected)
to deactivate. To use supervised input, install end-of-line
resistors. See connection diagram for information about how
to connect the resistors.
4
Internally connected to pin 1 (DC ground) when active,
and floating (unconnected) when inactive. If used with an
inductive load, e.g., a relay, connect a diode in parallel with
the load, to protect against voltage transients.
