In justice and law, house arrest (also called home confinement,
home detention, or, in modern times, electronic monitoring) is
a measure by which a person is confined by the authorities to
their residence. Travel is usually restricted, if allowed at all.
House arrest is an alternative to being in a prison while awaiting
trial or after sentencing.
While house arrest can be applied to criminal cases
when prison does not seem an appropriate measure, the
term is often applied to the use of house confinement as a
measure of repression by authoritarian governments against
political dissidents. In these cases, the person under house
arrest often does not have access to any means of communication
with people outside of the home; if electronic communication is
allowed, conversations may be monitored.
