Access control systems Servicing London & Home Counties

Being able to determine who has access to your building is a huge boost to security, and access control systems allow for full regulation of entry permissions, both to the property as a whole and to individual rooms and areas.

AAI Security Systems supply, install and maintain a range of high quality access control systems to customers throughout London and the Home Counties, providing a superior, safer alternative to traditional lock and key setups.

Access control device Latest systems that allow you to SEE or TALK to whoever is at your front door before you allow entry to your property.

Access control systems offer greater flexibility without compromising security - especially useful in working environments that see heavy foot traffic through different areas of the premises - and our experienced team are fully certified by both the NSI and the National Approval Council for Security Systems (NACOSS) for quality assurance.

AAI provide comprehensive maintenance contracts, including:

  • Intruder and access control devices
  • Checking and cleaning the locking mechanism
  • FREE replacement of batteries to ensure your system is always working
  • Systems for business, shops, offices and residential use

With video and audio systems available, you can screen visitors to your building before providing access. Our A/V and electric units are supplied by industry leaders BPT and Paxton respectively, meaning that we can fit access control components into existing systems for your convenience.

Keeping your access control system in pristine working order is essential for ongoing security. AAI are on hand to provide a full and thorough aftercare service for all access systems we install, whether one-off repairs, cleaning and battery replacement or regularly scheduled maintenance.
