<p>A remote confinement system provides a plurality of different unsupervised tests to determine the presence, identity or conduct of the prisoner. The tests preferably include an RF test performed continuously with an RF transmitter attached to the prisoner and a receiver (A4) at a remote confinement location, schedulable voice and breath tests performed to identify a person as the specified prisoner, and to determine the prisoner's sobriety. Equipment (20) at the remote location performs the tests in accordance with selection and scheduling information received in a prior automated communication with a central office host computer and stored in a memory (48) at the remote location. With the information, the host also sends an identification code of the transmitter attached to the specified prisoner. The remote unit (20) establishes communications, preferably, by dialing the central office over a telephone line (23). The RF test detects when the prisoner enters or leaves the remote location, and results in a warning being sounded if the signal from the transmitter is lost and delays transmission of the message to allow the prisoner to return following his departure.</p> |
