When You Need to Know What's Actually Happening, You Need Surveillance.
Statements lie. Memories shift. Stories change to fit whatever the situation requires. Surveillance documents what people actually did, where they actually went, and who they were actually with, with time-stamped, court-ready evidence that doesn’t depend on anyone’s word. If you’re at the point where you know something is happening but you can’t prove it, that’s exactly where surveillance starts. Our licensed investigators conduct discreet mobile and stationary surveillance across all 50 states, giving you the documented truth that changes what you’re able to do next.
Licensed. Discreet. Court-ready evidence, every time.

How we help
What Our Surveillance Investigations Include
Mobile Surveillance Operations
Vehicle-based surveillance documenting the subject's movements, destinations, and activities throughout the day, conducted by trained investigators using counter-detection methodology. We stay with them. They don't know we're there.
Stationary Observation
Fixed-position surveillance from undetected vantage points documenting activity at specific locations, residences, workplaces, meeting points, or properties of interest. When the location matters more than the movement, we hold position and document everything.
Multi-Investigator Team Surveillance
For complex cases requiring expanded coverage, multiple investigators coordinate through encrypted communications to maintain continuous observation through difficult traffic, transitions, and counter-surveillance scenarios that a single investigator can't handle alone.
Photographic & Video Documentation
High-resolution, time-stamped photography and video captured to evidentiary standards. Admissible in court. Verifiable through chain-of-custody protocols. The kind of evidence that doesn't leave room for argument.
Subject of Interest Identification
When someone unknown appears during surveillance, we identify them. License plate verification, photographic documentation, and follow-up background investigation when authorized. You'll know who your subject is spending time with.
Detailed Investigative Reporting
Every operation is documented in a comprehensive written report combining narrative findings, photographic evidence, video documentation, GPS data, and investigator observations, delivered in a format your attorney, insurance carrier, or organization can use immediately.

Warning Signs
When You Need a Surveillance Investigation
You Know Something Is Happening but You Can't Prove It
Suspicion isn't evidence. The people who need to take action, judges, attorneys, insurance adjusters, require proof. That's what surveillance produces.
The Story You're Being Told Doesn't Hold Up
Statements that contradict known facts. Schedules that don't match reality. Claims that need to be verified through observation rather than accepted on someone's word.
A Legal Proceeding Requires Documented Evidence
Divorce, custody, civil litigation, criminal defense, or insurance proceedings where the difference between "we believe" and "we can prove" is the difference between winning and losing.
An Insurance Claim Needs to Be Verified
Workers' compensation, personal injury, and disability claims where the claimant's reported limitations need to be measured against what they're actually doing day to day.
Standard Investigation Has Hit a Wall

You Think You're the One Being Watched

Patterns
What Our Surveillance Investigations Commonly Reveal About Subject Behavior
Surveillance investigations expose patterns case after case. While every situation is unique, our investigators repeatedly observe predictable behaviors when subjects believe they aren't being watched. Understanding these patterns is exactly why surveillance , not interrogation, not interviews, not document review, produces evidence that holds up under scrutiny.
Behavior Changes When the Subject Believes They're Alone
The most consistent observation in any surveillance investigation: subjects act differently when they don't know they're being observed. The version of someone you see in a courtroom, on a deposition, or during a confrontation is rarely the version surveillance documents.
Predictable Routines
Most subjects are far more routine than they realize. Within a week of observation, investigators can typically map daily patterns, predict transitions, and anticipate where the subject will be at any given hour.
Counter-Detection Failures
Subjects who suspect surveillance often try to detect it and consistently fail. Trained investigators identify counter-detection attempts, adjust methodology accordingly, and continue documentation without compromise.
Statements That Don't Match Activity
Surveillance routinely reveals contradictions between what subjects claim, to spouses, to courts, to insurance adjusters, to employers and what they actually do when they believe no one is watching.
Activity That Wasn't Expected
Surveillance frequently surfaces information the client wasn't even looking for: unknown relationships, undisclosed business activity, unexpected travel patterns, or behavior that explains questions the client hadn't yet thought to ask.
While these patterns alone don’t determine case outcomes, professional surveillance investigations transform what clients suspect into the documented record courts, attorneys, and decision-makers actually require.
Why Choose Us
Why Clients Choose Terrance Private Investigator & Associates for Surveillance Investigations
Surveillance is one of the most demanding disciplines in private investigation. Here’s what separates our work from the rest.
Professional Counter-Detection Methodology
Our investigators are trained specifically in counter-detection technique — unmarked vehicles, varied methods, route discipline, and operational behaviors designed to maintain observation without being identified.
Licensed & Insured Investigators
Every investigator on our team operates under a valid private investigator license and carries professional liability insurance. You're never working with an unlicensed operator or an unvetted contractor.
Multi-Investigator Team Capability
Complex cases require coordinated team surveillance. We have the personnel and operational coordination to maintain continuous observation through traffic transitions, location changes, and counter-surveillance scenarios that single-investigator surveillance can't handle.
Lawful Recovery Standards
We operate within the bounds of state recovery statutes, breach-of-the-peace standards, and chain-of-custody documentation requirements. Recoveries that hold up legally start with investigations that hold up legally.
24/7 Availability
Assets move on their own schedule. Our investigators are available evenings, weekends, and overnight whenever your recovery situation requires it.
How much does a surveillance investigation cost?
The cost depends on the scope, the duration, the number of investigators required, and the geographic complexity. Most surveillance investigations are structured around hourly rates with a retainer collected upfront. Multi-investigator team surveillance and cross-jurisdictional operations cost more than single-investigator local work. During your initial consultation, we provide a clear estimate based on your specific situation, no vague pricing or surprise charges.
Can the evidence you collect be used in court?
Yes. Our surveillance investigations are conducted to evidentiary standards, with documented chain of custody, time-stamped photographic and video evidence, and detailed investigator reports. Surveillance evidence is regularly used in family court, civil litigation, criminal proceedings, and insurance claims. Our investigators can also testify when needed.
How long does a surveillance investigation take?
It depends on what needs to be documented. Some cases, like documenting a single suspected event, can resolve in a single day of surveillance. Pattern documentation typically requires multiple days or weeks across the relevant time windows. We work efficiently to deliver findings in the shortest reasonable timeframe and structure operations to control costs.
How long does an asset Will the subject know they're being followed? investigation typically take?
Not when surveillance is conducted properly. Our investigators are trained specifically in counter-detection, varied methods, unmarked vehicles, route discipline, and operational behaviors designed to maintain observation without being identified. The first time most subjects learn surveillance occurred is when the evidence is presented in legal proceedings if it ever needs to be presented at all.
Is surveillance legal?
Surveillance conducted in public spaces by a licensed private investigator is legal in all 50 states. Our investigators operate strictly within the law, no illegal surveillance, no unlawful entry, no recording in spaces with reasonable expectation of privacy. The evidence we collect is admissible because it’s collected lawfully.
Do I need to be working with an attorney to hire a surveillance investigator?
No. Many of our individual clients aren’t represented by attorneys when they hire us they’re trying to gather information before deciding whether to retain counsel. We work with individual clients, attorneys, insurance carriers, and corporate clients across the full range of surveillance situations.
How is this different from your other investigation services?
Surveillance is the underlying methodology that supports many of our other services. Infidelity investigations rely heavily on surveillance. Child custody investigations include significant surveillance work. Insurance fraud investigations depend on surveillance documentation. This page covers surveillance as a service category but for specific applications, our Infidelity Investigations, Child Custody Investigations, and other dedicated service pages may be more relevant to your specific situation.
