摘要

The system has an antenna to transmit, receive and analyze an electrical field with respect to distortions. The system produces and analysis an electrical field (f) in a lock cylinder (c), door fitting or cylinder knob, such that conclusion on a closing state of a door leaf (b), a locking state of a lock case, rotation of a cylinder core, and movement type and direction of persons and objects in the near field of a door is enabled with respect to differentiation between entrance intention, passing before the door and break-in attempt.
