Surveillance cameras have been extremely effective in as a deterrent to crime. If airline passengers are made aware that the cabins are fitted with cameras that will record the whole flight, they will be less likely to become disruptive. The FlightVu internal cameras not only deter criminals, if an incident did occur in-flight the indelibly stamped recorded images (registering the time, date and location) would be admissible as evidence in court. This would aid and speed up prosecution of the offender.
