Within an access control system there is another important peripheral component, these are the Barriers and Turnstiles that will open the blocked access. There are vehicle barriers that can be low flow and high flow depending on the use that will be given to them: toll, perimeter, corporate, residential, among others. It must be considered that the quality of the barrier that you want to implement depends on the daily cycles, that is, the number of openings they have in a day and the speed with 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 arm of the barriers can be straight or retractable, with lengths that must be adapted to the size of the access.
To block or allow pedestrian access, there are tripod-type turnstiles that have 3 articulated arms, uni or bidirectional, they can support readers or be integrated into access controls. It is very important that they allow the release of the arm in case of emergency. There are more aesthetic turnstiles that are called folding turnstiles with tempered glass doors. They contain LED indicators or screens that show the status of the access or the person who wants to access.
Pivoting doors for services that require a larger access. There are also bollards that generally operate through hydraulic pneumatics that require the installation of a cistern.
These devices are integrated into an access control system through a controller card which in turn is controlled by the Access Control software.
