“Criminals no longer need to stake out a home or a business to monitor the inhabitants’ comings and goings. Now they can simply pick up wireless signals broadcast by the building’s utility meters.  In the US, analogue meters that measure water, gas and electricity consumption are being replaced by automated meter reading (AMR) technology. Nearly a third of the country’s meters – more than 40 million – have already been changed. The new time-saving devices broadcast readings by radio every 30 seconds for utility company employees to read as they walk or drive around with a receiver. But they are not the only ones who can tune in.”
