When a moving object violates this invisible red line, the probe will detect an abnormality and will alarm.

Infrared is a band in the electromagnetic spectrum that is between the microwave band and the visible band. Electromagnetic waves with wavelengths longer than 0.78 μm up to 100 μm belong to the infrared band. Since its wavelength is longer than the red light wavelength in visible light, it is located outside the visible red spectrum, so it is called infrared. Infrared light can also be called infrared light or non-visible light.
