The primary function of surveillance systems in security is to monitor activities and deter criminal behavior. Surveillance systems, which often include cameras and monitoring devices, provide real-time observation of a designated area. This monitoring serves as a powerful deterrent to potential criminals, as the presence of security cameras can make individuals think twice before engaging in unlawful activities.

In addition to deterring crime, surveillance systems also help security personnel review recorded footage to analyze incidents as they occur. This creates a safer environment for both properties and individuals, as constant monitoring helps ensure prompt responses to suspicious or criminal activities.

While collecting evidence for legal cases, recording employee attendance, and tracking inventory levels can be secondary functions in specific contexts, the overarching goal of surveillance systems remains focused on monitoring and deterring criminal conduct. This makes monitoring activities and deterring criminal behavior the most relevant answer in the context of security functions.
