What are common methods used for surveillance?

Closed circuit television (CCTV) and one-way tinted glass are widely recognized and standard methods used in surveillance practices. CCTV serves as a prominent tool for monitoring and recording activities in various environments, from public spaces to private properties, enhancing security and providing evidence in incidents. The ability to capture live footage allows for real-time assessment and response to potential security threats.

One-way tinted glass, on the other hand, enables individuals to observe an area without being seen themselves. This is useful in both security settings and in environments like interrogation rooms or observation posts, where discretion can be critical. Utilizing these methods in tandem offers an effective way to conduct surveillance discreetly while ensuring the safety and security of a space.

Other listed methods, while related to information gathering or assessments, do not represent traditional surveillance techniques. For example, drone usage and social media monitoring, though they have risen in popularity for certain types of observation, are more specialized and not as universally recognized as CCTV and tinted glass in the context of standard surveillance practices.
