The biometric visitor management system has become a necessity in the facilities where many people come and go. Schools, universities and hospitals use a biometric visitor management system enormously. Highly sensitive areas such as airports, railway stations, defense and secret government offices are prone to terrorist attacks. You are more likely to find a management system in these places. The face recognition management system is recommended for use in these locations. A face recognition device for visitor control and control provides greater precision and better security.

However, it can only be useful if you install a good instrument. When deciding to install a face detection biometric management system in your facilities, you may need to confirm your identification features. Good quality and advanced control and control can be used in face comparison mode 1 to 1 and in face comparison mode 1 to many. The 1-to-1 face matching mode is confirmation mode. The coincidence of faces from 1 to many is the state of identification. It is advisable to choose a biometric visitor management system that can work effectively both in verification mode and in identification mode.

The detailed explanation of the two modes can be given below:

* Verification (match 1 to 1): in this mode, a face template can be stored in the application database. The next time the face appears before activating the biometric visitor management system, the face matches the template. If the face matches the template, the identity is verified! This mode is best suited for regular visitors. For example, you own a large company with many employees. It is difficult for the receptionist to remember every single face. If the face is already stored in the database and the system can operate in confirmation mode, the receptionist can easily verify the person's identity.

* Identification (coincidence of 1 to many): In this mode, many face templates are stored in advance in the biometric visitor management system database. The program calculates the degree of similarity between the live face and those stored in the database. If the degree of similarity between the living face and any of the faces stored in the template is high, the face is considered to be identified. The program can return a list of possible people with similar faces. Or you can return the face identity live. For example, airports witness a large number of unique visitors daily. It is always under the threat of a terrorist attack. A database containing facial information on terrorists, mafia and other anti-social elements can be stored in advance. Each visitor may be required for the first time to perform the face recognition process in a visitor control and control. If the face is identified with any of the templates, the airport authority can take the necessary action.

The biometric visitor management system is a useful security tool. However, if quality is compromised, efficiency may not be maintained. When installing a visitor management and face recognition visitor, make sure it offers verification and identification modes. The greater the amount of advanced features in the application, the greater the security!
