What are the two forms of physical surveillance?

The correct choice identifies the two primary forms of physical surveillance as mobile and static/fixed. In the context of surveillance, mobile surveillance refers to the practice of observing subjects while moving, enabling personnel to follow targets as they change locations and activities. This type is often used to gather real-time information and provides a dynamic element to surveillance operations.

On the other hand, static or fixed surveillance involves monitoring a particular location or area without moving. This approach can be advantageous for observing specific behaviors or activities consistently over time without telegraphing the presence of the observer to the subjects being monitored.

Understanding both mobile and static surveillance is crucial for effective operational planning in law enforcement and security contexts, allowing for a flexible response to various situations while maintaining the integrity of the surveillance process.
