Access control systems are utilized to grant consent to persons/vehicles, thereby providing limited access in and out of a concerned location. These programs are highly advantageous when compared with the conventional locking and tracking systems.
Access control systems offer high security and also assist in having a check on the punctuality of individuals. These systems find a broad assortment of applications including colleges, businesses, parking lots, building sites and hospitals.
The majority of these systems have facilities to scan the thumb impression or the retina of the eyes of the people leaving or entering. Malpractice can be greatly cut down by using these systems. If you want to know more about Install Access Control Systems checkout http://www.hirelay.com/.
The conventional physical barrier or assess post cannot assure as much security as the electronic access control systems. By way of instance, if the test post is left open, the number of individuals entering can’t be found. Other instances like dodging the security employees may also happen. Whereas, the access management systems do not need someone to monitor the entrance.
Normal Access Control System
A normal access control system consists of a switched mode power supply (SMPS), a battery, relay, sensor and an exit button, which is a simple push button. The detector can be a card reader, bar code reader, scanner or a touch screen where information about the individual entering could be read digitally.On a printed circuit board, generally called as PCB, the connections are created. A 12V DC battery is enough to power this system.
The lock may be a card lock, touch proximity or lock. The wires from the detector including the input, output and battery lines are connected to the multi-pin connector on the board. To be able to ensure safe operation and the danger of a short circuit, it’s a good idea to connect the battery at the end of the installation procedure, (i.e.) after all of the other connections are finished.
The wire in the door that’s the access gate, is connected to a relay. This relay is a simple electrically operated switch, that’s the best suited since it’s a very low power switch.
The switch closes when the fed data was sensed and a command will be issued to the door lock system to mechanically open the door, provided the scanned data matches with the available/authenticated data.
