Within an access control system there is another important peripheral component, the Barriers and Turnstiles that will open the blocked access. There are vehicle barriers that can be low flow and high flow depending on their use: toll, perimeter, corporate, residential, among others. It must be considered that the quality of the barrier to be implemented depends on the daily cycles, i.e. the number of openings they have in a day and the speed at which they will open and close an access, with 1 second being the fastest and 3 seconds or more for those with heavier arms. The barrier arm can be straight or retractable, with lengths to be adapted to the size of the access.

To block or allow pedestrian access there are tripod turnstiles that have 3 articulated arms, uni or bidirectional, can support readers or can be integrated into access controls. It is very important that you allow the arm to be released in an emergency. There are more aesthetic turnstiles that are called folding with tempered glass doors. They contain LED or display indicators that show the status of the access or the person you want to access.

Pivot doors for services requiring larger access. There are also pylons or bollards that generally work through hydraulic tires that require the installation of a cistern.

These devices are integrated into an access control system through a controller card, which is in turn controlled by the Access Control software.
