Physical surveillance is the direct, in-person observation of a subject by a licensed private investigator. It involves monitoring a person's movements, activities, and associations in publicly accessible locations. Investigators may conduct surveillance from a stationary position, while moving on foot or by vehicle, or through a combination of both methods, depending on the subject and environment.
Physical surveillance means a licensed investigator watches and documents what a person does in the real world, such as where they go, who they meet, and how they behave. This is done in person, in public spaces, not through digital tracking or hacking. The investigator typically records observations through written notes, photographs, or video footage.
A spouse suspects their partner of infidelity and needs documented evidence of the partner's movements and associations during specific time periods. An employer or insurance company needs to verify whether a person claiming a disabling injury is engaging in physical activities inconsistent with that claim. A parent involved in a custody dispute wants factual documentation of how a child is being cared for during the other parent's scheduled time.
Licensed private investigators may conduct physical surveillance in any location where a subject has no reasonable expectation of privacy, including public streets, parking lots, and commercial properties. Investigators may not enter private property without permission, record inside private residences, or engage in conduct that constitutes stalking or harassment under applicable state law. Licensing requirements and specific legal boundaries vary by state, so investigators must operate within the laws of the jurisdiction where surveillance is conducted.
How long does a physical surveillance assignment typically take, and what documentation will I receive at the end?
The length of a surveillance assignment depends on the subject's schedule, the complexity of the case, and the specific activities being documented, so most investigators bill by the hour with a minimum commitment per session. At the conclusion of the assignment, clients typically receive a written surveillance report detailing the investigator's observations, along with any photographs or video footage collected during the operation. The quality and quantity of documentation will depend on what the subject did during the observation period.
Can a subject legally find out they were under surveillance by a private investigator?
If surveillance was conducted entirely in public spaces, it is generally lawful and the subject has no legal claim simply because they were observed. However, if a matter proceeds to civil litigation, surveillance reports and footage may become discoverable, meaning the opposing party could obtain them through the legal process. Clients should discuss confidentiality and potential disclosure with their attorney before initiating surveillance if a lawsuit is anticipated.
