Surveillance operations involve the systematic monitoring of individuals, groups, or locations to gather information. These operations can be conducted by law enforcement agencies, private investigators, or security firms. The methods used may include video cameras, drones, or electronic tracking devices to observe activities and behaviors. The primary goal of surveillance operations is to collect evidence or intelligence for various purposes, such as crime prevention, national security, or corporate security. Surveillance can also be used in counter-terrorism efforts to identify potential threats and ensure public safety.
