Description

Access video recorder based on face recognition system

Technical Field

The invention relates to the technical field of entrance guard video recorders, in particular to an entrance guard video recorder based on a face recognition system.

Background

The forbidden authority of the door is the guard and precaution of the door. The "door" herein, in a broad sense, includes various passages that can pass, including a door through which people pass, a door through which vehicles pass, and the like. Thus, the access control includes a vehicle access control. In the application of parking lot management, the vehicle entrance guard is an important means of vehicle management, and is not aimed at collecting parking fee, and is mainly used for managing vehicle access authority, and its entrance guard safety management system is a novel modern safety management system, and integrates microcomputer automatic identification technology and modern safety management measure into one body, and it relates to a large number of new technologies of electronic technology, mechanical technology, optical technology, computer technology, communication technology and biological technology, etc.. The method is an effective measure for realizing safety precaution management at the entrance and exit of important departments. The system is suitable for various essential departments, such as banks, hotels, parking lot management, machine rooms, ordnance depots, key rooms, office rooms, intelligent districts, factories and the like. The entrance guard system surpasses the simple gateway and key management, and has gradually developed into a set of complete entrance and exit management system. The system plays a great role in administrative management work such as working environment safety, personnel attendance management and the like, and has the functions of access control management, personnel information management, video linkage, alarm and linkage, event association function, electronic map, authorization transfer, batch management, focus personnel attention, trajectory analysis and the like. Strengthening and perfecting development are carried out based on the traditional entrance guard. Corresponding adjustment setting can be carried out according to different setting conditions; the grain warehouse-in and warehouse-out access control management system and method of the invention patent authorized by China with the publication number of CN103559746A meet different requirements of various markets, and model access control management process translation. The processes of registering customer information, issuing IC cards and issuing and hanging temporary license plates for license-free vehicles are standardized by the identity card recognizer, the fingerprint recognizer and the face recognizer. The design and installation of the vehicle number identification module and the barrier gate further limit the sequence of vehicle entering and leaving the factory, and only vehicles meeting the requirements are allowed to enter and leave the factory. The vehicle is from arriving at a gate sentry to entering a factory and leaving the factory, the flow is clear and standard, all vehicles entering and leaving the factory are well-defined, and the purpose of standardizing the flow is achieved, so that the existing method is continuously innovated and developed, and therefore the existing door control video basically meets the requirements of people, but some problems still exist.

However, the above door access recorder has the following disadvantages in use: video recording equipment is in the in-process of using, the display screen of the feedback of device to the user is easily destroyed, make the device inconvenient the protecting at the in-process of carrying out the video recording, present entrance guard video recorder for face recognition system that is based on in addition, still need carry out different orientation angle modulation under the video recording mode after carrying out license plate discernment of shooing and midnight, current general still need be equipped with electronic angle adjustment mechanism alone, make also need carry out angle adjustment mechanism's start-up control alone when the cost-push, for example, remote click etc. operation.

Therefore, an entrance guard video recorder based on a face recognition system, which can be conveniently adjusted and adapted to different working modes, needs to be designed.
