Traditional dome surveillance camera systems typically incorporate large heavy telephoto zoom lenses, which generate huge inertial forces that the drive train must overcome. Automatic points of interest can be pre-programmed which require the quickest Point-to-point response. The design challenge set by the client (Photo-scan) was to reduce the response time using the largest telephoto lens possible. This project was commissioned by HotHouse of London on a freelance basis. The resultant design reduced rotational inertia and increase performance by a staggering 30%.

Following a full engineering evaluation of the system constraints, the camera drive system was re-engineered from the ground- up. The pan-tilt gearing was optimised, and the main rotational motion updated with an opto controlled belt drive. A key innovation involved the redesign of the housing lid, making it a static and isolated from rotation, thereby minimizing inertia.
