Electronic Home Confinement
The term house arrest can also refer to electronic monitoring programs in which a convicted criminal is sentenced to home confinement instead of prison, for a specified period. The criminal wears an electronic ankle bracelet (for which he usually bears maintenance costs) that monitors movement and sends a signal to a central computer if the house arrest is violated. Examples of crimes that could warrant house arrest include white-collar crimes such as Fraud or Embezzlement. This type of sentence can be a cost-effective way of punishing criminals who pose no threat to others and thus do not need to be imprisoned at the state's expense.
