Access Control Somerst

Keypad Access Control

These systems consist of digital keypads, door release mechanisms and power supply. Digital keypads are fitted to one or both sides of a door to provide a secure means of access through the door by means of a code. There can either be a common code issued to all users of the system or individual codes (PIN – Personnel Identification Number) issued to each user of the system. Also connected to the digital keypad will be a door release mechanism, which will be rated to suit the security of the door. The power supply is connected into a local mains electrical supply and will provide power to the system.

Common codes usually provide low levels of security for small numbers of users in a controlled environment. The problem with a common code is that the code can be passed on to or learnt by third parties, which compromises the security of the door.

PIN's offer higher security, as users are less likely to divulge their own individual number.

Some systems can provide information and historical records on when PIN's have been used. This allows for the tracking of door operations/users, which is especially useful if there is a suspected security issue. For higher security or high numbers of individual users, 6 digit PIN's should be used in order to maintain the very low probability of guessing a PIN.

Keypads can be prone to vandalism when fitted in 'public access' areas. This type of Access Control Systems can be seamlessly integrated into Intercom Systems, if required.
