Table of Contents


To celebrate 40 years in business we thought we’d give you 40 interesting facts about the services we offer; 10 facts each for burglar alarms, CCTV, locks and access control.

Following from our 10 facts on burglar alarms, CCTV and locks, here are our 10 interesting facts about access control:

  1. Access control systems were first developed in the 1960s as a means of dealing with the issue of lost keys. Early systems used simple key pads
  2. An access control, or door entry, system simply means a system that allows you to control who has entry to a premises
  3. Access can be controlled via a key pad, fob, card, intercom or even biometric data such as fingerprints or retina scans
  4. Access control systems can record data such as who has entered and left and at what times
  5. Access control is common for large businesses, schools, banks and childcare facilities but can be used for domestic properties such as blocks of flats or the homes of elderly or disabled people who are unable to come to the door easily
  6. Access control systems are more secure than key locks as they can be lost or copied
  7. Means of access to an access control system can be withdrawn at any time, ie codes and fobs can be deactivated, giving you total control over who uses it
  8. Access control systems can be connected to alarms systems so they could be locked down in the event of the burglar alarm triggering or unlocked in the event of a fire alarm
  9. Access control systems can be fitted to internal and external openings eg internal doors and external gates
  10. Where a high level of security is required, two-factor authentication can be included ie 2 methods of authentication such as a code plus third party approval via video
