HP POLY 875S1AA Overview: This black HP Poly IP-Based Ceiling Microphone provides reliable, 360° voice pickup and Polycom Stereo Surround audio. Pair it with a Polycom video conferencing system or installed audio solution to eliminate conference table clutter by putting the microphones and electronics in your ceiling, freeing up your table surface for notebooks and other materials. The system allows you to define an audio area, in essence to create a virtual fence, to isolate sound capture within that fence for clearer audio. Add up to three additional systems to cover an area up to 1600²'.
