If the lock is non-polarized, we recommend you to add an external flyback diode.
Auxiliary connector
Use the auxiliary 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 auxiliary 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 or from the product's webpage.

Digital input – Connect to pin 1 to activate, or leave floating
(unconnected) to deactivate.
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. Each I/O is capable of
driving 12 V DC, 50 mA (max) external load, if internal 12 V DC
output (pin 2) is used. In the case of using open drain connections
in combination with an external power supply, then the I/Os can
manage DC supply of 0–30 V DC, 100 mA.
