The electronic monitor is a tool used as an alternative to secure detention and/or placement.  Juveniles wear a transmitter attached to their ankle that sends a signal to a receiver attached to their home phone.  When a juvenile is placed on the electronic monitor, a juvenile is given a strict schedule as to when they are allowed out of their home.  The unit monitors and detects any violations of that schedule, and if violations occur, appropriate action is then taken by the probation office.
