Axis P8221 Network I/O Audio Module provides eight configurable input/output (I/O) ports and audio capabilities to a network video system that either does not have such support or require additional support. Axis P8221 Network I/O Audio Module complements Axis network video products and integrates easily into existing network video installations using VAPIX. Sensors such as a door switch, smoke detector, IR detector or glass break detector, used for triggering an alarm event, can be connected as inputs. Output ports can be connected to control devices or relays, for instance, to open/close doors or turn on/off lights upon alarm.

It also has phantom power for a balanced microphone. Axis P8221 Network I/O Audio Module has support for Power over Ethernet allowing easy, cost-efficient and reliable installation.
