Be in control of who has
access to your premises

Whether you’re responsible for a school, hospital, industrial estate, residential or other property, you will want to make sure employees, residents and visitors feel secure and that equipment, belongings and information is protected.

ai security is the leading provider of access control systems in London, Essex and the South East. Our access control systems provide a reliable first line of defence against intruders while being unobtrusive and convenient for residents, staff and visitors, by managing access and regulating only authorised people to enter a premise or even a specific room and restricting access to unauthorised people.

Access control systems can be computer-based with an electronic card/fob access control system that uses a special “access card/fob”, rather than a brass key, to permit access into the secured area. There are a range of options available for granting access including PIN codes with keypads, ID cards, electronic fobs, radio frequency fobs and even biometrics.

Types of Access Control Systems


Stand-alone access control

Can be used to control access on one or many separate doors in a building. Access is gained by using a numeric code, or PIN with a keypad, or by presenting a proximity token or magstripe token, depending on which type of reader is fitted. As a result, each door has to be individually programmed. Stand-alone systems are great for smaller sites with a relatively small number of users, token management is simple, and the system can be extended easily as your requirements change.

Networked access control

Is a system where the doors are controlled from a central point or computer via a network. This system offers the flexibility of managing a single or multiple doors from a single point. These systems are great for medium to large sites as they make managing large numbers of doors and users easy.

Access Control Systems Benefits

High level of security

As the doors are controlled by powerful electromagnets, they are released only if an authorised person is detected. Should a fob go missing or a person is no longer allowed access the device or code can simply be removed from the system.

Reporting and
data collection

Computer-based systems allow organisations to track employee movements.


If someone loses their keys it often means expensive replacements or changing the locks completely. With an access control system, it is simply a matter of reprogramming the system to deactivate the lost card or fob and issue the person with another activated device.

Adjustable access levels

You can control and monitor entry to specific areas on the premises with different levels of access for different people – it is even possible to restrict entry and movement around a property for specific individuals.

High level of flexibility

Access control systems are flexible and can be used where restricted access is for just one door or for more complex requirements including multiple doors and timing restrictions. The system can also be programmed to release the locks when the fire alarm is triggered or during an evacuation so that safety is not compromised to achieve security.
