What Separates Miami Surveillance Investigators When the Ratings Are All High
If you’re hiring surveillance in Miami, the Google stars won’t make the choice for you. Every firm on this list is rated 4.8 or 5.0. What separates them is what comes back from the job. That can range from footage alone to a full package: timestamped video, a written timeline report, chain-of-custody records, and an investigator who will testify. Know which one you’re paying for before the first day in the field.
The second difference is when you can reach someone. Crossroads and Specialized Investigations Consultants keep weekday hours. Wasser Investigations keeps Monday to Friday office hours, ISOG is open every day until 6pm, Grey Ghost answers until midnight, and PI Fast is listed open around the clock. Wasser Investigations works from Coral Gables and takes cases in Miami. See the South Florida areas we cover.

What to Ask Before You Book Surveillance in Miami
Use these questions with any investigator on this list. At Wasser Investigations, a surveillance job comes back with timestamped video and photos, a written report with a timeline, and chain-of-custody records. An investigator is also available to testify. Ask every other firm what its version of that package includes.
Ask how fees are billed and what a full day of surveillance will cost before work starts.
Ask whether you will receive timestamped video and photos, a written report with a timeline, and chain-of-custody records.
Ask whether the investigator will sit for a deposition and testify if the case goes to court.
Ask who you will talk to during the case and how fast they reply.
Ask how footage will be delivered to you or your attorney.
Ask for the agency’s Florida license number and proof of insurance before you sign.
What Surveillance Costs and Where Florida Law Draws the Line
Most Miami firms quote surveillance by the hour, and few post a price. Miami Investigation Corp is one that does. As of October 30, 2026, it lists covert surveillance at $100 to $200 an hour, with a 4-hour minimum. Mileage, gas and parking are often billed on top. Get the hourly rate, the minimum and the expenses in writing before the first day in the field.
Florida law also sets limits that no license lifts. Three of them shape every surveillance job.
No secret audio. Florida requires the consent of everyone in a private conversation before it is recorded. Recording without it is a third-degree felony under section 934.03.
No hidden GPS trackers. Putting a tracking device on another person’s car or other property without consent is a third-degree felony under section 934.425. The law’s business exception does not cover a private investigator hired by someone else, unless that client would qualify on its own.
Public places only. An investigator films what anyone could see from a street or other public spot. Trespassing to get a shot is off the table.
Ask any firm how it keeps its work inside these lines. Evidence gathered the wrong way can hurt your case instead of helping it.
