Biometric visitor management system has become a must in premises, where many people come and go! Schools, universities, and hospitals make use of a biometric visitor management system immensely. Highly sensitive areas like airports, railway stations, defense, and secret government offices are prone to terrorist attacks. You are most likely to come across visitor management and control in these places. Visitor management system with face recognition is advisable for use in such places. A face recognition device for visitor management and control offers higher accuracy and better security.

However, it may serve the purpose only if you install a good instrument. When you decide upon installing a biometric visitor management system with face detection in your premises, you may need to check its identification capabilities. Good quality and advanced visitor management and control can be used in 1-to-1 face matching mode and 1-to-many face matching mode. The 1-to-1 face matching mode is the verification mode. The 1-to-many face matching is the identification mode. It is wise to choose a biometric visitor management system ...
... that may function efficiently in the verification mode as well as identification mode.

Detailed explanation about the two modes may be given as below:

*Verification (1-to-1 matching): In this mode, a template of the face can be stored in the database of the application. Next time, the face appears before the biometric visitor management system live, the face is matched with the template. If the face successfully matches with the template, identity is verified! This mode is most suitable for regular visitors. For example, you own a big company with many employees. It is difficult for the receptionist to remember each and every face. If the face is already stored in the database and the system can functioning under verification mode, the receptionist may be able to easily verify the identity of the individual.

*Identification (1-to-many matching): In this mode, many face templates are stored in advance in the database of the biometric visitor management system. The application computes the degree of similarity between the live face and the ones stored in the database. If the degree of similarity between the live face and any of the faces stored in the template is high, the face is considered identified. The application may return a list of possible individuals yielding resembling faces. Or else, it may return the identity of the live face. For example, airports witness a large amount of unique visitors daily. It is always under the threat of a terrorist attack. A database containing the facial details of terrorists, mafia and other anti-social elements may be stored in advance. Every first-time visitor may be required to go through the facial recognition process in a visitor management and control. If the face is identified with any of the templates, necessary action may be taken by the airport's authority.

Biometric visitor management system is a useful security tool. However, its effectiveness may not be maintained if quality is compromised. When you install a visitor management and control with face recognition, you should ensure that it offers verification and identification modes. Higher the amount of advanced features in the application, higher the security!
