The Polycom EagleEye Director Camera Base (2201-82559-001) is a sophisticated base unit for a professional video conferencing system that automatically detects and frames active speakers in a room without manual remote control. This base requires two separate Polycom EagleEye II or III cameras to function as a complete, automated system.The EagleEye Director system revolutionizes the group video conferencing experience by acting as an "invisible" video production director. The base unit contains an array of seven integrated microphones used for voice triangulation, precisely locating where a person is speaking in the room, up to 25 feet away. Once the voice is located, advanced facial detection algorithms direct the two connected cameras to pan, tilt, and zoom in on the active speaker, framing them in the optimal proportion for remote participants to clearly see facial expressions.
