Researchers at University College London are developing a wireless system that could allow continuous, real-time radar-style detection and tracking of people or objects in any area with wireless network coverage.In most current situations intrusion detection is accomplished with PIR sensors, while more sophisticated target detection and tracking systems rely on co-operative targets, such as with RFID, which requires subjects to carry a tag, or have restricted coverage including systems using video surveillance, which may have their vision blocked by objects such as parked cars. Both CCTV and RFID require the installation of high-cost equipment.
But according to UCL's researchers, WiFi-based tracking could be developed with low-cost wireless hardware using the 802.11 standard. It would be able to be used indoors and outdoors and would allow monitoring to take place without the subject's knowledge or co-operation.'The system could be deployed anywhere with a WiFi capability using the existing infrastructure.
Furthermore, by using the longer range WiMax technology a detection range of up to 40 Km could be achieved.
This, and other advanced developments in intrusion detection, will be addressed in the new Specifying Security Technology Course, due to be launched in 2008. Contact David for details.
