420-line 50-meter infrared camera
The infrared camera was a kind of camera equipment that integrated a camera, a protective cover, an infrared lamp, a power supply and cooling unit, and so on. 420 lines indicated the camera's definition level. The higher the number of lines, the clearer the image. 420 lines belonged to the relatively lower definition specifications. 50 meters means that the effective detection range of the infrared camera is 50 meters. The working principle of this camera was to use the spectral characteristics of the infrared light that could be sensed by ordinary black-and-white CCD-based cameras, and to use infrared lights as an " illumination source " to achieve night vision imaging. The infrared camera technology was more commonly used in the field of security monitoring. Its development trend was digital, intelligent, network, and integrated, which could easily link other security equipment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

noise meter
A noise meter, also known as a sound level meter, noise detector, decibel meter, etc., was the most basic noise measurement instrument. It was an electronic instrument, but it was different from objective electronic instruments such as a voltage meter. When converting sound signals into electrical signals, it could simulate the time characteristics of the human ear's response speed to sound waves. It had the characteristics of different sensitivity and the intensity characteristics of different loudness. It was a subjective electronic instrument. It measures the sound level and frequency of environmental noise to assess the impact of noise on human health and the environment. Common noise meters such as the VC824 digital noise meter have a measurement range of 30 - 130dBA, 35 - 130 dCC, a storage environment humidity of 10 - 80%RH,and a use environment humidity of 10 - 70%RH.1 The novel " Flood Dragon " is equally exciting.
