Honeywell Home IS335 Wired PIR Motion Detector with Pet Immunity, 40' x 56' Range

• Sealed Optics: The sealed optical chamber prevents drafts and insects from affecting the detector.
• Uniform Sensitivity Optics: Whether an intruder is directly in front of the sensor or at the edge of a protected area, the custom designed Fresnel lens provides a consistent level of detection—delivering optimal performance no matter what the distance. Shorter precision focal lengths mean superior optics and detection.
• Wall-to-Wall Coverage: Wide and long detection coverage for coverage range protection that exceeds similar products in the market.
