Security Surveillance


Established in 2005, our mission at SDL Security Limited is simple: to provide high-quality security solutions for our valued clients. This is exemplified by Qolsys, the newest addition to our PowerG secure wireless burglar alarm systems, that can incorporate Z-Wave home automation devices, and when using the powerful App it also also allows CCTV cameras, and the Skybell video doorbell to be integrated on to the system

Prior to becoming Managing Director of SDL Security Limited Graham Inniss had 13 years working for BT before becoming the Security Coordinator for electronic security systems at Imperial College London.

The experience gained at one of the worlds top universities resulted in Graham eventually starting a security company that was soon bought out by a large Australian access control company, who then employed him as European General Manager.

Before starting SDL Security, Graham went on to work for a top London based security company with NSI Gold Approval, this experience was invaluable when setting up SDL Security.

SDL Security obtained NSI approval for Intruder Alarms, Access Control, and CCTV, and also became a CAMEsafe gate automation installer. We have relinquished our NSI staus since moving to Dorset, however we still have systems that would meet the standards.

Graham has planned, installed, and / or maintained systems for Imperial College, Coca Cola HQ in London, Garden Studios, The Science Museum, Siebel Systems, Customs House, The Cobden Club, Calvin Klein, McKinsey and Co, Spearmint Rhino, Solus Norwich Union, councils, schools, public houses and many others institutions.
