Tensor's group of companies are a leading supplier of CCTV surveillance, Visitor Monitoring and Access Control technologies and because it is accredited and performs to the highest standards, the group expects any regulation to have little effect on its professional business practices. For instance, in 2009, Westminster City Council was told to turn off 100 digital cameras, mostly used for parking enforcement, after the government found that the equipment did not meet technical standards. This is not a problem for Tensor, who use only the best equipment from the leading manufacturers.
