Embodiment 1

[0014] A night vision surveillance camera that filters out visible infrared rays, comprising: a housing, an LED drive control circuit board built in the housing; a lens fixed in the housing; an LED module and a window glass arranged in front of the lens; The monitoring camera also includes: a filter for filtering out visible infrared rays and an LED driver control board circuit are arranged between the LED module and the window glass, and the method for analyzing the video monitoring image of the night vision monitoring camera is: calling the function provided by the OpenCV open source library , to develop image analysis modules with functions such as cross-line detection, cross-line counting, area intrusion, wandering detection, items left behind, and items lost. This module provides an interface for inputting various parameters, and performs corresponding image analysis according to the parameters, outputs the analysis results to the caller, and develops the video analysis se...

Abstract

The invention relates to the technical field of monitoring cameras, specifically to a night vision monitoring camera capable of filtering visible infrared rays. The night vision monitoring camera capable of filtering visible infrared rays comprises a housing, an LED drive control circuit board internally installed in the housing, a lens fixed in the housing, and an LED module and window glass arranged in front of the lens, and the monitoring camera also includes an optical filter arranged between the LED module and the window glass and an LED drive control panel circuit. The night vision monitoring camera capable of filtering visible infrared rays prevents easy exposure of a target when working at night or in a dark environment.

Description

technical field [0001] The invention relates to the technical field of monitoring cameras. Background technique [0002] With the strengthening of security awareness, more and more surveillance cameras are used in all aspects of life, followed by higher requirements for the stability and service life of surveillance cameras. [0003] For example, when a surveillance camera is used during the day or in a well-lit environment, the light-catching effect is better and the image is clear. If the surveillance camera is used at night or in a dimly lit environment, the image will be blurred due to insufficient light. Therefore, surveillance cameras with infrared night vision function appear, and the infrared night vision function is realized by generating infrared rays through LDE infrared lamps. [0004] In a video surveillance system, with the continuous expansion of the system scale, the number of cameras is also increasing. For an increasingly large number of cameras, the res...
