"Keep under surveillance" is a phrase commonly used in law enforcement and security contexts, which refers to the act of monitoring or observing someone or something closely for an extended period. It involves the systematic and continuous scrutiny of an individual, a group of individuals, or a specific location, usually with the purpose of gathering information or ensuring security.
When one keeps something or someone under surveillance, they employ various techniques and tools to covertly or overtly observe their actions, movements, or communications. This can include employing physical surveillance techniques such as stakeouts, using CCTV cameras, or even technological means like tracking devices or wiretapping. The intention behind surveillance is often to prevent or investigate criminal activities, gather evidence, protect national security, or maintain public safety.
Keeping someone under surveillance can involve a range of professionals, including law enforcement agencies, intelligence services, private investigators, or security personnel. It may be legally authorized through warrants or court orders in some jurisdictions, while in others, certain surveillance activities may be subject to legal restrictions or require specific justifications.
The concept of keeping someone under surveillance can extend to both overt and covert methods, depending on the circumstances and the level of secrecy necessary. Overall, the term implies a continuous watchfulness and monitoring of an individual, group, or location to ensure safety, law enforcement, or the acquisition of information, often serving as an essential tool in maintaining security and solving criminal investigations.
