Surveillance cameras serve a critical function in security by deterring criminal behavior through monitoring. The visible presence of cameras can discourage potential offenders from engaging in illegal activities, knowing that their actions are being recorded. This deterrent effect is supported by research indicating that environments with active surveillance experience lower rates of crime. Additionally, surveillance footage can be invaluable for investigations, providing law enforcement with evidence to solve crimes that may occur despite the monitoring.

While other functions mentioned in the options, such as providing personal security for staff or entertaining guests, are noteworthy in different contexts, they do not capture the primary role of surveillance cameras in a security framework. Surveillance is fundamentally about monitoring and maintaining safety, thereby reinforcing the importance of option B. The notion that surveillance cameras would block all entrances misrepresents their intended actual function, which is to monitor rather than restrict access.
