We've done some updates to multiview, and have been able to run 20+ 1080p h264 cameras on an AppleTV 4K. The number of cameras is highly dependant on the video resolution, type of compression used, your internal network speed, and the stability of the camera stream. Make sure to connect your AppleTV to an ethernet connection for best performance.
