The modern PIR infrared detector (rev. P) offers detection range of up to 18 m and a coverage angle of 85.9° for reliable interior security. Animal immunity 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 actual movement. Digital temperature compensation, front tamper protection, and an elegant design complement the practical implementation for modern interiors.
