PRACTICAL CONSIDERATIONS OF PATROL MONITORING The PSP is a small weatherproof computer with LCD readout. It contains an accurate clock and is powered by standard alkaline batteries which last several years. Each one contains a unique set of keys which are combined with the clock to generate a new “random” number every 5 minutes. This “random” number is converted to one entry in a short list of computer phone numbers which is displayed on the LCD. The guard must read the display and use his cell phone to dial the selected computer phone number. The computer system registers the number dialled together with the caller ID. The appropriate ticket is updated if the right number is dialled, otherwise an exception is raised. The call is equivalent to a missed call, which does not attract a charge from the network.
