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. (Contains 3 tables, 2 figures, and 7 notes.)
