Houston Surveillance
Investigations

If you’re considering surveillance in Houston, it’s usually because something already doesn’t add up and you’re tired of guessing.

Terrance Private Investigator & Associates runs discreet, evidence-based surveillance across Houston and Harris County — mobile and stationary, time-stamped, and built to hold up when it counts. You bring the suspicion; we bring the documented facts.

How we help

Every situation is different, and every investigation starts with a conversation. We listen, answer your questions, and recommend the best approach based on your goals. Whether you need proof, peace of mind, or evidence for court, we’re here to help.

  • Infidelity

    Discreet infidelity investigations that give you clarity instead of endless second-guessing. The most common call our Houston team gets starts with “I feel crazy, but…” — and you’re almost never crazy.
  • Child Custody

    We document what’s really happening during the other parent’s time, so your attorney has facts instead of he-said-she-said when it matters most.
  • Background Checks

    Know who you’re really dealing with — a new hire, a business partner, or someone your family just got serious with. We find what surface searches miss.
  • Surveillance

    Professional surveillance across Houston for personal, legal, and corporate matters — documented with clean timestamps and chain of custody.

Who we serve

With 17+ years of surveillance experience across Houston, we know how this city moves — the traffic that can blow a follow on the 610 Loop, the access patterns around office towers and gated communities, and the timing it takes to document the right moment without ever being noticed. That field knowledge is the difference between footage that proves your case and a report that falls apart. Every case is handled with discreet mobile and stationary surveillance and clear, court-ready documentation.
