MultiSync® WD551 is an all-in-one smart solution for modern meeting spaces. Supporting "Bring Your Own Meeting (BYOM)" scenarios, users simply connect their own device via the secure USB-C cable to immediately share content and start video meetings using already familiar Microsoft tools, such as Office 365 and Microsoft Teams. The bezel-free PCAP optically bonded touch screen is easy to clean and provides a superior writing experience whether interacting via finger or active pen, supporting Windows Ink and palm rejection. With integrated IoT sensors, the WD551 gathers telemetry from its environment such as room occupancy, temperature, ambient light and air quality data, which supports smart building strategies. Ideal for small meeting spaces encouraging spontaneous meetings, users perform to their full potential with the tools and environment optimised for productive creativity.
