VCM38

What the VCM38 picks up in a meeting room

The Yealink VCM38 is a ceiling microphone array built around eight microphones that capture speech from every direction. Beamforming locates the person speaking and focuses pickup on their voice, while echo cancellation and Yealink noise-proof technology reduce echo and background noise. Voice activity detection, comfort noise generation and background noise suppression are also included.

Yealink rates a single unit to cover 40 square metres. The recommended pickup range is 3 m, with a maximum of 6 m. For oversized rooms, up to eight VCM38 units can be combined in one system, spreading pickup across the room instead of relying on one device.

Specifications that matter when planning

• Frequency response: 100 Hz to 16 kHz
• Signal-to-noise ratio: 60 dBA at 1 kHz
• Maximum sound pressure level: 100 dB SPL at 1 kHz, THD below 1%
• Power: PoE to IEEE 802.3af through one RJ45 port for both Ethernet and power
• Power input: PSE 54V 0.56A or PoE 48V 0.27A
• Dimensions: 127.3 x 127.3 x 66.3 mm
• Operating temperature and humidity: 0 to 40°C and 5 to 90%

The unit has a dual-colour LED indicator, and the package includes a 30 to 60 cm telescopic rod and a quick start guide.

Where it fits in Qatar

Three situations suit this model well:

• A ministry meeting room in Msheireb, where staff join Zoom Rooms or Microsoft Teams Rooms sessions with colleagues abroad and need the table kept clear for papers and laptops.
• A lecture or seminar room at a campus in Education City, where the presenter moves around the table and pickup needs to stay consistent.
• A head office meeting room in the Industrial Area, where a ceiling array keeps the table uncluttered during site and project reviews.

Because the operating range tops out at 40°C, the VCM38 belongs in an air-conditioned room, away from air conditioning outlets and vents as the installation guidelines advise. Summer temperatures in Qatar can exceed 45°C outdoors, so confirm that the room's cooling is reliable before fixing the unit to the ceiling.

What to plan before installation

Yealink recommends mounting at 2.5 m (8 ft) above the floor, adjustable to the actual site, and keeping the unit away from other obvious noise sources. Check that the PoE switch or injector at the network cabinet supports IEEE 802.3af before ordering, and plan a cable run to every ceiling position. For a room larger than 40 square metres, the number of units depends on room shape and table layout. A free site survey from SmartRooms Qatar can check ceiling height, air vent positions and cable routes before you commit to a quantity.

A discontinued model: what owners and buyers should know

Yealink has discontinued the VCM38 and no longer accepts new orders for it. Under its end-of-life policy, existing units receive hardware and software technical support plus security and bug fixes in the first year after end of sale. From the second to the fifth year, Yealink attempts software bug fixes, but new features are not provided. Spare parts depend on local distributors and inventory. Yealink names the CM20 as the recommended replacement, and SmartRooms Qatar can prepare a quotation for it or for another current equivalent that suits your room.

To request a quote for a replacement, or to arrange a site survey for your meeting room, contact the SmartRooms Qatar team and include the number of rooms and their sizes.
