Which of the following is NOT typically monitored by surveillance systems?

Surveillance systems, particularly those set up for public safety and crime prevention, generally focus on monitoring activities that occur in public spaces or areas where safety and order might be at risk. Traffic patterns, public gatherings, and crime hotspots are common targets for surveillance. These systems are often deployed to manage traffic flow, ensure safety at large events, and identify areas that may require a higher police presence due to previous incidents or reported crimes.

Personal phone conversations do not fall under the typical purview of such surveillance systems. Monitoring private communications is subject to stringent legal restrictions and privacy laws, which differentiate it from the other surveillance activities mentioned. For this reason, personal phone conversations are not typically included in the monitoring activities of standard surveillance systems aimed at ensuring public order and safety.
