An access control represents a secure way to give staff, customers and visitors access to your building. Where keys can be lost or stolen, an access control system operated via intercom, proximity fob or card, keypad or even a biometric system offers a very flexible security system that allows you to set access permissions for individuals and track movements in and out of your premises. This access can be added, changed or revoked very easily without having to rely on people returning keys. A keyless door entry system is also the most effective way to manage buildings of multiple occupancy.
