An access control system is the first step in protecting your people, property and assets, by tracking and restricting door, gate or other entry point access to a property, building or room to authorized persons. With an access security system, you know exactly who enters a building or room, when they enter and what door they use. Access systems include analytics that allow you to track where your employees are and receive reports of suspicious activity, such as attempts to access restricted areas.
Key card-, key fob-, biometric- (finger print, retina scan, and etc.) or PIN-based access control systems provide you the ability to lock and unlock doors. Many organizations utilize technology cards for employee badges to track and authorize access to restricted areas.
Access control is the selective limitation of contact to a place or to any other resource. An individual needs a permission to access any restricted area is known as authorization. In earlier days access control is maintained using the persons like guard and ticket checker. As the growth of technology, now a device is used for an access control in all places. If an access control is achieved by a human then it is said to be a physical while it is through mechanical locks and keys are preferred. An access control system verifies who is allowed to enter or exit and where and when is the important thing about this system. Those who have the key to open the lock they can only enter into the room depending on this access control system are configured. With the help of computers electronic access control solve the restriction of mechanical locks and keys. Based on the credential it grants access to the user those who have mechanical keys. When right to use is authorized the door is unlocked for a programmed time and the transaction is recorded.
A keycard is a security token that grants you access through electrically-powered doors. These systems require a keycard reader (installed on the door) and you gain access by either tapping your card on the reader (proximity reader), swiping it (swipe reader), or inserting it (insert reader).
With keycards, users no longer need to insert a metal or traditional key into a tumbler lock to gain access. Instead, there is an embedded access credential on the keycard magstripe, or as a chip in the card itself, and this is read by the keycard reader each time you attempt an unlock. If the unique code on your card is recognized by the reader, permission is granted for access.
Once the reader recognizes the access credential, it then communicates with the door lock. The smart access control reader will be wired to an electric lock on your door and it will send a signal to the lock to start an unlock event. With a good system, the whole process takes less than a second.
Proximity card systems are considered an industry standard. Featuring 125 kHz proximity technology, proximity systems work with 125 kHz technology readers and credentials — printable PVC cards, clamshell cards, key fobs and tokens.
