Access Control System is the need of today life. We see when we go to any reputed company or office some of cabins are as restricted are to enter. No-one can enter in that area who is not allowed to be entered. This is just why Access Control System. By it’s name we can understand, it controls the entry. When somebody input credential (Like Finger Print, Card Impression, Face Recognition), it receives it and recognise whether it is approved or not. If credentials are already assigned it gives approval, otherwise denies. There are three type of controller, Biometric, Card, and Face Recognition. It comes of two types i.e. software based and Standalone. Software based system provides data in server like in – out date with id, name etc. And Standalone System is for only to control entry, there is no data, who entered inside?
