Face recognition is safe, quick and easy to use and works without physical contact. The Adatis-technology is working with a three-dimensional acquisition of the face in invisible infrared light. When a face in front of the camera is detected, a 3D scan is started and features generated from the 3Dmesh are compared against features stored in a database. If the person standing in front of the door is enrolled, i.e. in the data base, the door opens automatically.
