VCM34

What the VCM34 is and how it fits a Yealink room

The Yealink VCM34 is a video conferencing microphone array. It is an audio input device rather than a camera or codec, and it passes room sound to a Yealink video conferencing system or a Yealink UVC PTZ camera. Yealink has discontinued this model, and it stopped accepting new orders from 31 January 2024. That makes it most relevant to organisations that already own the unit, to buyers comparing it with newer models, and to anyone who needs a replacement for a unit in service.

Pickup range, cascading and power

A built-in three-microphone array gives the unit 360 degree pickup. The datasheet quotes 3 m (10 ft) for high-quality pickup and a maximum of 6 m (20 ft). The frequency response runs from 100Hz to 12KHz. The unit also includes background noise suppression, voice activity detection, comfort noise generation and acoustic echo cancelling, along with Yealink Noise Proof Technology.

Power arrives over Ethernet under IEEE 802.3af, with a rated input of PSE 54V/0.56A or PoE 48V/0.27A. Two RJ45 ports handle the Ethernet and power connection and the cascade link. Up to four units can be cascaded with Yealink video conferencing systems, and up to six with Microsoft video conferencing systems. The package includes a 3 m Ethernet cable, a silicone pad and a quick start guide.

Where it fits in Qatar

• A 12 to 20 seat boardroom in West Bay or Lusail: one unit placed at the centre of the table gives remote participants clear pickup from every seat within its 6 m range.
• A seminar room in Education City with a long table: two or more units can be cascaded along the table, within the four-unit limit for Yealink systems.
• A training room in Msheireb running a Microsoft-based system: the six-unit cascade limit suits a larger room where a single microphone would leave corners poorly covered.

What to plan before you order

The datasheet gives an operating range of 0 to 40°C and humidity of 5 to 90%. Outdoor temperatures in Qatar often pass 45°C in summer, so the unit should be used in an air-conditioned room, away from direct sunlight, window glare and open-air areas. If the room environment is unclear, ask the SmartRooms Qatar team to confirm it before you order. Check the PoE port budget on your switch and plan cable routes. The unit measures 169 x 171.5 x 37.5 mm.

SmartRooms Qatar supplies and delivers to all eight municipalities of Qatar and offers professional installation, with a free site survey beforehand. Government ministries and schools can order against a purchase order or a government tender. Because this model is discontinued, we recommend including a current replacement in the same quotation.

Support and replacement

Under Yealink's end-of-life policy, support for a discontinued product is staged. The first year after end of sale includes full support, years two to five cover bug fixes where feasible, and new features are not offered after end of life. Spare parts depend on local distributors. Yealink recommends the VCM35 as the replacement. Request a quote for the VCM35 or another current equivalent, and the SmartRooms Qatar team will help confirm compatibility with your existing Yealink system.
