Possible applications of this technology include monitoring offenders in their homes during the confinement portion of the split (shock probation) sentence, during intensive supervision, on pretrial release, and during postincarceration programs. Noteworthy features of electronic surveillance include its simplicity, its reliability and accuracy, its safety and economy, and the capacity of one system to accommodate a large number of clients. Application of electronic surveillance to these programs could provide the means for reducing institutional populations in the State while also reducing the staggering costs of confinement. 23 footnotes.
