The tough new Security Grade Super Stealth has "Can't Miss" 360° detection for fast installation and flawless operation. It's the most technically advanced sensor on the market today. Comes completely assembled and pre-wired for quick installation. Two powerful detectors combine to give the Stealth 360 180° long forward range plus superb 360° motion detection below and to the sides. Impenetrable!
