There are different types of turnstile to suit your requirements such as the half-height flap or tripod turnstile and full height turnstile. Different modes in accessing the turnstile such as a security personnel pushing a button, or, integrating the turnstile with a door access system is also available for additional level of security. For absolute control, the full height turnstile is ideal as it only allows for people to pass through at one at a time and the chances of tailgating incidents is very slim.
