09741220 cites 5 patents.

A multi-spectral detection device is provided that includes a housing, a bezel spacer, a microphone, an end cap and electro-optical sensors mounted to the end cap. The housing has an inner chamber that holds sensor components. The bezel spacer has a first end and an opposed, second end. The first end of the bezel spacer extends from a first end of the housing. The bezel spacer has a central bezel passage leading to the inner chamber of the housing. The bezel spacer further has at least four side walls. Each side wall is positioned 90 degrees away from an adjacent side wall. A microphone is coupled to each side wall of the bezel spacer in such a manner that each microphone is faced 90 degrees with respect to an adjacent microphone to form a compact acoustic array. The end cap is coupled to the second end of the bezel spacer and the electro-optical sensors are mounted to the end cap.
