What are the 2 types of surveillance?

The correct answer identifies the two fundamental approaches to conducting surveillance: formal and informal. Formal surveillance typically involves systematic and organized methods, often adhering to legal guidelines and protocols, making use of equipment such as cameras or technological tools. It is usually planned and executed as part of an official investigation or operation.

On the other hand, informal surveillance can happen in a more casual or unstructured manner. This might involve observing subjects without specific permissions or formalities and can be performed by anyone, including civilians, in everyday situations.

Understanding these two types helps law enforcement officers determine the appropriate approach for various scenarios, considering factors like the requirement for documentation, the presence of legal oversight, and the operational objectives of the surveillance.

The other choices, while they describe different types of surveillance techniques or contexts, do not capture the broader classification that formal and informal provide. For example, static and mobile refer to whether the surveillance is conducted from a fixed location or while in motion, and plain clothes and in uniform describe the attire of the officers conducting the surveillance rather than the methodology of the surveillance itself. Meanwhile, daytime and nighttime denote the time of day in which surveillance occurs, which does not categorize the nature or intent of the surveillance itself.
