Surveillance isn't just a tactic used by law enforcement or corporations. Individuals may also find themselves under observation-sometimes by competitors, sometimes by suspicious partners, and occasionally by those with malicious intent. While not always easy to spot, there are warning signs that may indicate you're being followed or monitored.
At National Business Investigations, Inc. (NBI), our decades of experience in professional surveillance give us unique insight into the telltale behaviors and patterns that most people miss.

Surveillance doesn't always happen on the street. In some cases, people notice odd phone interference, unexpected static, or unexplained battery drain-possible signs of electronic monitoring.
If you notice people consistently looking your way, lingering in your proximity without clear purpose, or engaging in small talk that seems to probe for personal details, it could be part of a broader effort to track your activity.
