Technical Field

[0001] The present invention relates to the field of infrared detection devices, and in particular to an infrared contour detection device for objects at a fire scene. Background Art

[0002] An infrared detector is a device that converts incident infrared radiation signals into electrical signal outputs. In an infrared detector, a pyroelectric element detects the presence or movement of a human body and converts the output signal of the pyroelectric element into a voltage signal. The voltage signal is then subjected to waveform analysis to facilitate target detection. It can be used for real-time tracking of multiple targets, including pedestrians and vehicles, in complex infrared scenes.

[0003] Most existing infrared detection devices are not easy to adjust according to the required detection range and angle, and most of them are not easy to clean.
