The system, developed by the company ThruVision, is normally used by astronomers to study dying stars. According to its inventors, although the T5000 can "see" through clothing, it does not reveal people's physical details or subject them to any "harmful radiation" such as that associated with security systems that use X-rays.
The camera uses "passive imaging technology" to identify the natural electromagnetic rays, known as terahertz rays or T-rays, that objects emit. The T5000 was exhibited on March 12 and 13 at a scientific exhibition organized by the British government.
The hiring of private security services, as well as purchases of detection and alarm systems increased last year. Companies that are engaged in industrial activities, financial institutions and shops, are the most important customers for this industry, although residential security continues to represent an important turnover for the sector. Some 750 companies gathered at SICUR, the largest Spanish fair for comprehensive security and one of the main references in the sector in Europe.
