The causal model analysis of resident's evaluation of Closed Circuit TV and security perception

Closed Circuit TV(CCTV) was considered to be an effective technology for crime deterrence in Taiwan. But the resource of CCTV effectiveness always came from police administration, and there were little studies exploring the relationship among community surveillance, public space environment, situational crime prevention, security perception and Closed Circuit TV evaluation from residents' viewpoint. This study developed one integrative model to examine their causal relationships quantitatively. We collected 830 community resident samples around Taiwan and used structural equation modeling(SEM) to verify those hypotheses we explored. The results showed that resident's perception of community surveillance, public space environment, situational crime prevention all positively influenced security perception and Closed Circuit TV evaluation.
