Abstract

The invention provides a night vision infrared camera detection device based on a near infrared spectrometer, a roller is arranged on the lower surface of a sliding base, two electric winding devicesare respectively arranged on two sides of the upper surface of the sliding base, a telescopic assembly is arranged between the two electric winding devices, and supporting assemblies are uniformly fixed on the telescopic assembly. The supporting assembly comprises a supporting rod and supporting pulleys, the supporting rod is fixed to the telescopic assembly, the supporting pulleys are fixed to the two ends of the supporting rod respectively, the transmission device conducts transmission around the two electric winding devices and the supporting pulleys, and a hanging device used for hanging the detection optical fiber box is arranged on the transmission device. Aiming at the characteristic that infrared rays with the wavelength of 850-940nm supplement light for night visual monitoring, anear-infrared spectrometer is used for quickly and accurately detecting the infrared rays in the wave band, so that the detection accuracy is effectively improved, and the detection misjudgment rate is reduced.

Description

technical field [0001] The invention relates to the technical field of near-infrared spectrometers, in particular to a night-vision infrared camera detection device based on near-infrared spectrometers. Background technique [0002] Hotel accommodation during travel is a very necessary requirement of life. However, with the development of monitoring technology, various micro-cameras are placed by criminals in hotels and other places involving private personal information of citizens to achieve the purpose of voyeuristic privacy. At present, the commonly used pinhole camera detection method is a signal detector, which scans the full frequency by emitting radio waves, and identifies the pinhole camera according to the different response signals to the radio waves in the conductor. This method is often interfered by other conductors in the room, resulting in The detection accuracy is low and the false positive rate is high. [0003] In recent years, the development of surveil...
