Access Control System-Reliability

The main purpose of access control system is to prevent loss and crime, so it must have high reliability. An access control system may not give an alarm most of the time, so there is no need to give an alarm. The probability of alarm is generally very small, but if the alarm system fails within this very small probability, it often means disaster arrival.
