Cisco Spark Board uses a new 4K camera that captures a high-resolution, wide-angle (+/- 89 degree) image of virtually the entire room. It uses dynamic framing to give you the best possible view of people in the room. As for the microphones, it uses a 12-microphone array that automatically amplifies and modulates speaker voices through the room. The built-in mics not only keep tables clear of wires, but you don't get stuck hearing people shuffling paper and coffee cups anymore. You'll also find more information in the data sheet.
