Many security entrance lanes today are optical turnstile portals employing moving, mobile barriers of metal, glass or acrylic in some cases. The barriers can be drop arms, swinging glass, retractable (sliding) glass, or other materials. The sensing technology has improved to a higher level of security violation detection, as well as to allow for faster throughput.
