In the short term, it envisages that tiny hidden cameras will soon be commonplace around the home and residential neighbourhoods and could even stop burglaries before they happen. They would use facial-recognition software to spot known criminals and sound the alarm, in a scenario reminiscent of The Minority Report.
It forecasts the birth of an 'automated Neighbourhood Watch', where the new generation of intelligent alarm systems installed in homes will communicate with each other, collecting details of the behaviour of a suspicious stranger on the street or alerting others to danger. More outlandishly, burglar alarms may emit a low frequency sound or high-intensity strobe light to disorientate intruders and force them to leave empty-handed.
