Access Control System across 5 UK Sites for International Organisation


Sigma is proud to have supplied an access control system to an international organisation with a well recognised brand, where the system is installed across 5 of the organisation’s UK sites controlling in excess of 80 doors and the movement of 1200 employees all from their HQ in London.

The distances between sites and the need to control the entire system from a single location at HQ where amongst the challenges needed to be overcome. Sigma also identified, having carried out a full assessment of the client’s business process, that local control at each of the other remote sites was essential.

Sigma therefore chose a system that was capable of communicating across a wide area network and multiple simultaneous control locations, whilst being modular in design, allowing for further expansion in the future to accommodate more remote sites and controlling additional doors.
