Citywatch Security are approved installers for fitting this exciting and award winning innovation of British Technology. The Smokecloak system is designed to rapidly fill an area with a thick dense vapour which not only has the effect of deterring the would-be thief from entering the building but once in the building will find it impossible to see the equipment he wishes to steal or his way out. The vapour used is completely non-toxic and leaves no trace once it has dispersed.

The manufacturers boast a 100% success record and use the slogan: "You cannot steal what you cannot see".
