Is it correct that surveillance can be conducted through mobile or stationary means?

Surveillance can indeed be conducted through both mobile and stationary means. This statement is correct because surveillance methods are varied and adaptable to different operational needs.

Mobile surveillance involves the movement of personnel or devices to track or monitor subjects as they change locations. This can include following a target in a vehicle or using drones to observe a large area from different angles. Mobile surveillance is advantageous because it can provide dynamic insights into a subject's activities or patterns without revealing the intent to observe.

On the other hand, stationary surveillance entails setting up observation points at fixed locations to monitor a specific target or area over an extended period. This can include fixed cameras or personnel positioned at a vantage point where they can observe and record activities without being noticed.

The effectiveness of both methods depends on the circumstances and objectives of the surveillance operation, making it essential to understand that both mobile and stationary approaches are legitimate and commonly used in security and law enforcement operations.
