A system according to the invention may include: an access control system and a central control unit. The access control system may include: one or more entry checkpoints to a premises, a plurality of controllable gates, a plurality of cameras and a local control unit. The local control unit may be configured to: obtaine, for at least one camera from the plurality of cameras, a stream of images of one or more persons approaching a checkpoint, and extract from the obtained images dynamic identification data. The local control unit may further be configured to stream the extracted dynamic identification data to the central control unit. The central control unit may be configured to: create a motion based identification vector from the extracted dynamic identification data, compare the motion based identification vector to stored identification motion based vectors, and calculate one or more confidence level scores for identifying the one or more persons approaching the checkpoint.
