Monitoring camera device and application method thereof

Abstract

The invention provides a monitoring camera device, comprising a monitoring camera and an LED light supplement lamp which is arranged in the same direction as the monitoring camera, wherein the LED light supplement lamp comprises a shell, and a circuit control module and an LED lamp that are arranged inside the shell; a reflection cup and a light transmitting window are arranged at the front end of the shell, the circuit control module is connected with the LED lamp, the light transmitting window is matched with the outlet of the reflection cup, the light transmitting window is provided with a convex lens, and the power of the LED lamp is 5-50W. The invention also provides an application method of the monitoring camera device. According to the monitoring camera device provided by the invention, the phenomenon that the headlamp of the vehicle directly illuminates the monitoring camera can be avoided, and the tailing phenomenon in the camera shooting process can be completely avoided; the adopted light supplement lamp has low power and is energy-saving and environmentally friendly; the light emitted by the light supplement lamp is uniform and soft, the sight line of the driver cannot be affected, safe driving of the driver can be guaranteed, and high security can be achieved; and the identification rate of vehicle registration plates can be increased, and the requirements of the intelligent license plate retrieval for the image clarity can be met.

Description

technical field [0001] The invention belongs to the field of monitoring camera devices, and in particular relates to a monitoring camera device used for monitoring and shooting traffic at night. Background technique [0002] At present, the license plate recognition of moving vehicles at night is mainly realized by bayonet cameras and electronic police (essentially still bayonet cameras) auxiliary flash lights. However, the above two devices are expensive and the installation process is complicated. They are not suitable for large-scale popularization and cannot achieve safety. Requirements for full coverage of city surveillance. Ordinary high-definition surveillance cameras at night to identify moving vehicle license plates mainly rely on constant light sources to fill in the light, but they cannot suppress the strong light of vehicles and solve the phenomenon of screen smearing, and the recognition rate is extremely low. The traditional supplementary light method uses hal...

AI Technical Summary

Problems solved by technology

[0004] The monitoring camera device in the prior art has problems such as high energy consumption, poor safety, and smearing phenomenon on the screen. How to use a monitoring camera device and method at night, which can not only suppress the strong light of the vehicle, but also identify the license plate of the moving vehicle, It is a difficult problem in the monitoring industry. There have been no successful cases at home and abroad. With the intelligent and in-depth application of high-definition monitoring, social needs are more urgent
