Counter Surveillance (TSCM)
Protecting Your Privacy Across the Dallas–Fort Worth Metroplex.
At Lone Star Detectives, we specialize in Technical Surveillance Countermeasures (TSCM) — commonly referred to as bug sweeps or counter-surveillance sweeps. Our experienced investigators use advanced detection equipment to locate and neutralize hidden surveillance threats in homes, some small businesses, vehicles, and personal items. Whether it's a covert listening device, hidden camera, GPS tracker, or wireless transmitter, our team identifies and eliminates electronic surveillance with the highest level of discretion, precision, and professionalism.
Who We Serve
Our TSCM services are trusted by:
- Attorneys and law firms
- Private citizens and families
- Domestic violence victims and stalking targets
