Abstract

A remote recording unit, which is worn by a child, monitors the ambient sounds in a day care center (for example) and records selected sound bytes that are played back on a docking unit. The time duration between sound bytes is periodic and re-programmable. The remote recording unit is "childproof" and tamper-evident to generate an internal "flag" which will be displayed on the docking unit, indicating that the remote recording unit was removed by an unauthorized person. The device is equally applicable to a patient, older person or pet left in the care of a third person or persons or placed in a facility or institution.
