Which Security Devices Reduce Burglary

This chapter examines how protection is conferred by different security device combinations. Window and door locks, in combination with security lighting, are shown to be particularly effective, demonstrating the importance of restricting access (by locking windows and doors), simulating occupancy and increasing surveillance potential (using security lighting). It is contended that different security devices have distinctive primary mechanisms – some deter (e.g. discourage an offender from selecting the property), and some thwart (e.g. physically impede entry). It is important to examine the effectiveness of specific device combinations with respect to domestic burglary with entry and attempted burglary (separately) as failure to do so risks masking any underlying (and important) changes.
