AXIS P8221 I/O Audio Module 0321-002
Enhances video surveillance systems with additional I/O
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 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.
