AXIS P8221 8-Configurable Digital I/O Audio Module Ports

Bring flexible audio and control to networked security installations with the Axis Communications AXIS P8221 Network I/O Audio Module. Designed for surveillance and monitoring applications, the P8221 converts legacy sensors and control devices into IP-enabled events—supporting eight configurable digital I/O ports to connect door switches, glass-break sensors, relays and more. Integrated two-way audio (half- or full-duplex), a built-in low-power speaker amplifier and phantom power for balanced microphones provide clear communication and on-site voice deterrence without extra amplifiers. PoE support reduces cabling and installation time, making the module ideal for retrofits and distributed monitoring points. Tight integration with Axis cameras and VAPIX® streamlines camera-triggered actions and centralized management, improving response times and operational efficiency. NDAA-compliant construction and a compact metal housing ensure dependable performance in commercial, retail, transportation and facility monitoring environments.
