First Responder Technologies, founded by an ex-member of the Royal Canadian Mounted Police, Kal Malhi, is changing the way our communities use wifi to combat the growing number of public attacks and mass shootings.
The technology uses commercial WiFi networks to identify concealed weapons. The product itself is a fence which acts as a WiFi antenna transmitter and receiver and would be placed around the perimeter of public buildings. The technology currently being developed would then be able to detect metals of certain sizes and shapes. If identified, the system would activate a camera installed to confirm the identity of the person (essentially to ensure it is not a police officer etc.)
The purpose of the fence is to provide law enforcement authorities with the knowledge of an attack before it even happens. This extra 10 to 15 seconds allowing local security or law enforcement to prepare, respond and diffuse the situation.
