Access Control and Time-Keeping Systems Access Control and Time-Keeping Systems
These can be used to restrict access to some areas, to avert trespassing to some areas, or to keep track of the people who have access to those areas. Using these systems, employee time-keeping has become safer and more efficient than ever. Employers can now know exactly the time employees arrive and leave, and how much time they spend at work. The access control and time-keeping system have the following components: access control panel (and/or time-keeping), card reader (magnetic or proximity), code keypad, fingerprint reader, REX buttons (request to exit), software, electromagnetic lock.
Access Control Panel – the device that manages the access control points, readers, modules, locks, etc. It processes the electromagnetic lock’s open/close inputs and stores all access data. Based on these stored events, various time-keeping reports can be created, exported and used in accounting programs.
Proximity Card Reader – reading the proximity card is made when it is put in front of the reader, with no need for direct contact with the reader. The reading distance differs for different readers and cards.
Biometric Reader - biometric technology allows foolproof person identification based on their fingerprint. This method is one of the safest, because it guaranteed that no one can clock in for someone else. There are different biometric readers: fingerprint reader, iris scanner, palm scanner, voice scanner.
Access Keypads – often used due to their easy operation. Testing a viable code will activate the door to open.
REX Buttons – used in the cases where exiting a secure area is not controlled.
Software – allows programming the system and the reader, defining access levels, defining and displaying reports, on-site device control, etc. For it to work, the control panel must be connected to a computer through RS232/RS485 or through the control panel’s Ethernet port.
