This device, according to its original properties and characteristics, has created to control the passage of people to one or another territory. However, today there are many different models and types of turnstiles, which differ not only in appearance and design, but, of course, the main properties. For example, if we consider full -speed and semi -rost options, their differences will be visible to the naked look, and the main functions are fundamentally different. The first devices ensure safety much higher than the second. This is primarily due to the fact that they have a rather bulky and large design that is attached in the right place, and covers the entire passage present there. Thus, go through this device, jump over it, or even transfer some objects it becomes simply impossible.
