AXIS P13-B Box Camera Series
Specifications
The internal microphone is used by default; the external microphone is used when connected. You can disable the internal
microphone by connecting a plug to the microphone input.
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 (12 V 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.
Supervised input - Enables possibility to detect tampering on a digital input.
Digital output - For connecting external devices such as relays and LEDs. Connected devices can be activated by the VAPIX®
Application Programming Interface, through an event or from the device's web interface.

Can be used to power auxiliary equipment.
Note: This pin can only be used as power out.

Digital input or Supervised input – 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
Digital output – 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.
