AXIS P8221 Network I/O Audio Module provides additional I/O and audio capabilities to network video surveillance systems that do not have such support or require additional support. AXIS P8221 complements Axis network video products and integrates easily into existing network video installations using VAPIX®.
AXIS P8221 has eight digital I/O ports that can be configured as either inputs or outputs. Input ports can be connected to sensors such as door switches, smoke detectors or IR detectors. Output ports can be connected to control devices or relays, for instance to open/ close doors or to turn on/off lights, and control them remotely.
AXIS P8221 provides two-way audio in half or full duplex. Audio can be encoded in high quality AAC at up to 128 kbit/s bit rate with 32 kHz sampling.
AXIS P8221 has a built-in pre-amplifier and phantom power which eliminates the need for an external power solution when using balanced microphones, and can provide savings in installation costs. The input for the balanced microphone has an adjustable gain to allow for improved adaptation of microphones with different output levels.
AXIS P8221 has support for Power over Ethernet allowing easy, cost-efficient and reliable installation. With the built-in serial server support, AXIS P8221 enables legacy devices and temperature sensors to be connected to the system using RS-232, RS-422 and RS-485.
