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 con-
nected 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 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 installa-

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 allow-
ing 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.
