Which is not a characteristic of Technical Surveillance?

Technical Surveillance primarily relies on electronic means to monitor and gather information without necessitating physical presence. This includes various tools and tactics, such as cameras, listening devices, and other electronic equipment, which allow for the collection of data remotely.

The use of recording devices is a hallmark of technical surveillance, enabling operators to capture audio or visual information that can provide critical insights without being on-site. Additionally, the ability to utilize the Internet for information gathering underscores the advancements in technology that have expanded the capabilities of surveillance operations, allowing for remote monitoring and data collection through various online channels.

In contrast, the requirement of physical presence suggests a more traditional form of surveillance, which typically involves direct observation or interaction. This characteristic contradicts the fundamental nature of technical surveillance, which emphasizes remote operations through technology.
