Access control system is used to deny access to uninvited visitors, and allows authorized persons to pass through the door. The key issue is, who is authorized to access where and when?

Stop! Please show your ID! This is usually happened when unauthorized persons were once prevented from getting into the buildings. Security staff, gatekeepers or doormen often still closely monitor who is permitted to pass through a door, and who isn't.

The company building, offices and warehouses hold all manner of valuables and data calling for maximum protection against theft, espionage and vandalism. Some public places like the office building, the metro station, the airport also hold the manners to forbid the persons unauthorized, what should we do for this purpose? The Access Control System may help a lot.

Modern access control systems electronically regulate who can go where within a building or site, and when. They are customized to the type of company, its operational processes and traffic flows.

For example, the hospital, hotel, airport, metro station, office building and other types of places have particularly sensitive areas which need to be protected against unauthorized access. In hotels, only hotel guests are permitted access to their room or the wellness area. Conversely, department stores grant all users access during business hours, but allow only authorized persons to enter outside these times. And while all employees need access in manufacturing companies, only certain staff should access hazardous or highly confidential areas.

The Key Parts Of Access Control System

Access control system consist of at least 3 part as below .

1st. The identification media, like ID card.

2nd. The Card Reader, which records the identification information and data and forwards this to a door controller (DC) or access control unit (ACU) for evaluation and administration.

3rd. The Door Controller (DC) checks the access authorization and grants or denies release of the door.

The additional door and bolt contacts are connected to the Door Controller to monitor the status of doors (closed, locked, open). This identifies any manipulation and break-in attempts and triggers alarms.

Modern access control systems can manage the access rights described above both online and offline. Offline systems consist of digital cylinders and door fittings and, in contrast to an online system, the authorizations are saved on the ID card.
