The modern PIR infrared detector offers a detection range of up to 18 m and a coverage angle of 85.9° for reliable interior security. Immunity to animals up to 10 kg reduces false alarms caused by pets. Advanced 3D optics and IFT technology ensure precise focusing of the infrared signal on the pyroelectric sensor and help recognize real movement. Digital temperature compensation, front tamper protection, and elegant design complement the practical execution for modern interiors.
