Who we are
Local, licensed, and quiet about it
Hart Investigative Group is a North Carolina firm specializing in technical surveillance countermeasures and private investigation. We work out of Cornelius and cover the Charlotte and Lake Norman region — close enough to be at your car or your kitchen table the same week you call.
Most of our clients call because something feels wrong and they need a straight answer before making a decision. That is the work: find out what is there, document it properly, and hand you something you can use.

Frequently asked questions
Still unsure? Calling costs nothing and commits you to nothing.
How do I know if I am being monitored?
Common signs: someone knows where you have been without being told, your car battery drains unexpectedly, there is unfamiliar hardware under the dash or in the OBD-II port, or a new device or gift appeared in your home. None of these prove anything alone — a sweep is how you find out.
Will anyone know I contacted you?
No. You choose how we reply — text, call with or without voicemail, or email — and our replies are deliberately neutral. We never mention the nature of your inquiry in a message someone else might see.
What does a sweep cost?
It depends on the space and its size: a single vehicle is at the low end, a full residence or an office suite takes longer. We quote a flat price on the call before scheduling, so there are no surprises.
How soon can you come out?
Usually within a few days, and sooner for urgent situations. We work by appointment, including evenings and weekends, so the visit fits your routine rather than disrupting it.
Are you licensed?
Yes — Hart Investigative Group LLC is a licensed North Carolina firm, and our TSCM work follows the same legal and ethical standards as our investigative work.
