VPM220W connects to the videoconferencing endpoint using Wi-Fi to enable the following:

Placement
The microphone array's position can be adjusted based on the number of conference attendees and the placement of seats in the conference room.

Networking
Thanks to its strong signal stability and anti-interference capabilities, VPM220Ws can be networked with videoconferencing endpoints using Wi-Fi, which eliminates the need for cascading.

Management and maintenance
VPM220W has no external cables, which prevents accidental disconnections.


360-degree sound pickup with an optimal pickup distance of six meters.
Anti-interference wireless signals.

The combination of a VPM220W and HUAWEI TEX0 videoconferencing endpoint not only achieves AEC, AGC, and ANS, but also reduces power consumption of the microphone array because all audio processing operations are performed by the videoconferencing endpoint.

Designed to use minimal energy, VPM220W requires 2 W power at most when running and 0.7 W power on standby.

VPM220W is provided with a battery and charging socket for both a single and cascaded microphone arrays. A fully charged battery provides 8 hours of use time or 24 hours of standby time.
