The Effectiveness of an Electronic Security Management System in a Privately Owned Apartment Complex

Poisson and negative binomial regression methods are used to analyze the monthly time series data to determine the effects of introducing an integrated security management system including closed-circuit television (CCTV), door alarm monitoring, proximity card access, and emergency call boxes to a large privately-owned complex of apartment buildings in New York City. Crime rates in a control apartment complex under the same ownership, and in the police precinct in which the 2 complexes are located, serve as controls.
