Ceiling Microphone Array
Clearer and Smoother Audio Experience
VCM38 is a newly designed ceiling microphone with 8 built-in microphones for 360-degree voice pickup. It de-
livers excellent voice quality with high-quality echo cancellation and Yealink noise proof technology. With Beam-
forming technology, VCM38 can automatically locate and optimize voice pick up for the person speaking. A
single VCM38 unit can cover 40 square meters, even for oversized meeting rooms by using up to eight units in
one system.
VCM38 supports PoE, which enables simple and easy deployment. It can be installed directly on the ceiling
or by a telescopic rod which can be adjusted between 30~60cm to keep the room table clean, and can match
more meeting room scenarios.
