Electronic access control uses computers and processors to solve the limitations of mechanical locks and keys. A wide range of personal credentials can be used to replace mechanical keys. The electronic access control system grants access based on the credential presented. When access is granted, the door is unlocked for a predetermined time and the transaction is recorded. When access is refused, the door remains locked and the attempted access also recorded. The system will also monitor the door and send or sound alarms if the door is forced open or held open too long after being unlocked.
The primary purpose of access control is protection. By issuing electronic access rights, you can safely protect assets, information, processes, employees and the public, so that only those with permissions have access. Electronic access control takes this principle further by tracing “who, where and when” by recording and reporting on this data.
Electronic access control eliminates the needs for multiple key holders and dramatically reduces the cost associated with lock changes when keys are misplaced. Cardholder access rights can be revoked site wide, in an instant, improving security and crisis response. Reports can access the length of time workers have been on site, where they have been and if they have attempted to access unauthorised areas. Alarms like doors being left open or forced can be flagged in real-time therefore limiting and containing threat.
