ANPR (Automatic Number Plate Recognition) technology is increasingly common. It is used in security camera installations on garage forecourts, large carparks and in overhead gantries on many roads.
PMP harnesses ANPR in a handheld format to speed patrol times. Gone are the days of writing a list of number plates on a notepad. Handheld ANPR even eclipses the typing of registrations into a PDA. With PMP you can walk through a carpark gathering registrations and timestamps in a fraction of the time it used to take.
Vehicle registrations are stored with a timestamp in the handheld device so that on the next warden patrol any overstay can be highlighted and acted upon.
