The IM Series security window intercom system features an unobtrusive acoustic tube that contains a microphone and speaker. The acoustic tube concept allows full visibility to approaching customers, while negating the need for cutting holes in barrier glass. Service providers will enjoy crisp, clear two-way audio communication using the adjustable gooseneck microphone or optional headset. Applications include ticket booths at theaters, theme parks, stadiums and stations as well as service windows in banks and consulates. Aiphone Corp.
