Currently, we automatically identify many people at the same time in the camera image. We recognize their faces in the crowd, as well as their clothing and personal features, such as gender, age, glasses, mustache, beard, or features of their equipment, such as telephone by the ear, helmet, mask, protective vest, backpack, bicycle, etc. Acquired in this way the information goes to the database, which can be searched quickly based on the above-mentioned criteria.

 

   Face recognition systems are used, among others in access control, e.g. for automatic opening of gates, for recording working time, e.g. for verifying the identity of employees passing through gates, for notifying security personnel about the appearance of an unknown person or a blacklisted person, for notifying staff about the arrival of invited guests or important persons, to track the movement of certain people around the site, etc. The list of applications of this type of system seems to be limited only by the investor's imagination and the law.
