The MVC S90 set comes standard with two UVC86 cameras that support 12x optical zoom and intelligent tracking. The cameras can be independently controlled and switched between layouts via the MTouch Plus control panel using Yealink RoomConnect. You can combine the MVC S90 with the MVCBYOD extender; simply connect the USB cable to the PC to freely use the audio and video devices of the entire system. Additionally, multiple devices from the MVC S90 series can be combined with network cables to create a conference room system that can be flexibly merged and shared.
