IP-A1AF

IP audio interface

The IP audio interface shall be integrable into SIP environments via the open SIP protocol (according to RFC3261) and into VMS using the ONVIF® Profile S audio backchannel. Furthermore, the interface shall be addressable via multicast, providing 20 slots for listening addresses, and via HTTP commands using its remote API (Application Programming Interface).

The audio shall be put out to a line audio output and a low impedance speaker output, supplied by an internal amplifier with 15 W speaker power. Also, an audio input for usage in SIP and ONVIF calls shall be available, providing a Line/Mic switch and phantom power supply.

The IP audio interface shall provide an internal storage for up to 20 audio files accepting the WAV and MP3 format. Up to 20 patterns shall be programmable for audio file activation including adjustable repeat intervals, play count setting, duration setting and timer functionality.

All device settings shall be executable through a browser interface and in addition, a free-of-charge setting software for adjusting the network setting of a group of IP devices simultaneously shall be available.

The IP audio interface shall receive its power supply over the network connection using PoE+ or PoE.

2 control inputs for activation of playback patterns, audio mute or initiation of SIP calls (up to 2 destinations) shall be accessible via a removable terminal plug. 1 control output for triggering local devices shall also be included.
