IP-A1AF
The IP-A1AF is a PoE-powered Audio Interface that decodes IP audio streams into analog audio signals. It equipped itself with a built-in 15 W amplifier to drive low-impedance speaker(s) and internal storage, onto which can store up to 20 audio files. Analog audio and control outputs can also be connected to an external amplifier. It supports SIP protocol for integrations with VoIP devices, and its 20 multicast ports are available for group paging operations. It can also receive broadcasts from Video Management Systems (VMS) via ONVIF backchannel. Device control and further system integration is accessed through remote API (HTTP) or local control inputs.
