Uses DiscovaCam Limited (DiscovaCam) uses proprietary technology to provide protection against unwanted surveillance. There are two primary markets for the technology: personal protection and site protection. Personal Privacy Hidden surveillance cameras have become increasingly common since the early 1990s. The majority of these cameras are deployed legally, if at times with dubious ethics. Court decisions in Britain have supported evidence gathered by hidden cameras in locations such as toilets and public restrooms, where discovery of the camera would have likely forced its removal. The infamous case of the photographing of Princess Diana whilst exercising at a gymnasium highlighted the lack of protection against unwanted intrusion. The introduction of cameras integrated into cellular telephones has added a further dimension to the situation, with images being able to be transmitted within seconds of capture. These images have been used in a variety of ways. Law enforcement officers have identified suspects and victims near scenes of crime. Journalists have collected images in support of stories. Employers have spied on employees to detect misuse of company resources and to raise productivity. Companies have used cameras to bug conference and meeting rooms to discover corporate secrets. Internet pornsters have sourced material by spying with cameras and posted the content on Internet websites. The common result is that the distinction between being in a public place and having personal privacy is being blurred. Privacy legislation is generally ineffective, as people in a public place generally have little protection in a public place, and secondly, must first be aware that they have been photographed before it is possible to lay a complaint. The uncertainty of such surveillance can produce continuous tension and stress. DiscovaCam provides an opportunity for people to detect hidden equipment around them and retrieve the knowledge of privacy. People under legitimate surveillance can act in the full knowledge that they are under public scrutiny, while illegimate uses of cameras can be detected and eliminated. Site Protection Site protection has become increasingly difficult, with the miniaturisation and increasing distribution of camera equipment. The seriousness of site protection ranges from detecting camera equipment spying on public baths to catching terrorists canvassing high-profile targets. The common requirement is to detect camera equipment from entering areas from which they have been banned, and alerting security staff to the culprit. Site protection can involve anything from a single detection unit mounted at the entrance to a room, detecting equipment as it enters the premises, to an elaborate network of units providing a comprehensive and overlapping surveillance of a large or complex location. Site protection units have commercial uses in areas such as shops (to catch thieves canvassing a site or competitors checking prices), gymnasiums and public baths (where people usually do not wish to be photographed), corporate and government offices (to detect surveillance by visitors), museums, art galleries and universities (to protect intellectual property) and remote banking facilities (to prevent the reading of people’s PIN numbers on credit and EFT-POS cards). Security agencies have more complex requirements, usually involving the prevention of reconnaissance by a potential threat or loss of classified information. DiscovaCam has a range of products to provide the necessary level of protection appropriate for the site. The threat offered by cameras to an organisation’s reputation and to its secrets can be significantly reduced.
