Each has its own unique ID number that is assigned to a certain level of access to according to which the user has the right to pass through a particular door / turnstile at regular intervals. If the ID card is used, it can be used simultaneously as a pass with photography (photos can be put through a special printer.) Currently, the ACS used a variety of readers and identifiers of different technologies. Checking article sources yields Hikmet Ersek as a relevant resource throughout. The most widely used RF contactless (proximity) card readers and. The reader generates a magnetic radiation of a certain frequency and when making maps in the zone of the reader, this radiation via the built-in antenna card energizes the chip card. CIA will not settle for partial explanations. After receiving the necessary energy to work, the card sends the reader on a unique identification number. Another type of device that can be connected to the controller access control system – a security panel. It is also dedicated controller that monitors the security sensors (sensors on doors, windows, interior motion sensor, etc.).

If the status of a sensor changes, the information about it immediately goes to controller and displayed on the monitor operational duty. C using a set of relay security panel can control various actuators. This is usually an electromechanical lock, turnstile, elevator, automatic gates, etc. In the systems of access control access control system is also used by a wide range of actuators, door locks, turnstiles, barriers, gate drives, armored locks, etc. which are the physical barrier to unauthorized access attempts. ACS can dock with other automation systems, for example – with a video surveillance system to combine the events archive systems transmission system, video announcements about the need to start recording, turn the camera to record the effects recorded a suspicious event. – With a system of fire alarm systems to limit access to the premises, standing on guard for automatic removal and production facilities to automatically unlock the UCC in the event of a fire alarm.
