Surveillance - GreenVets LLC


Surveillance is a cornerstone of many Private Investigations and in many instances it becomes the keystone supporting the entire case.

Even with the development and widespread use of GPS Vehicle Tracking, which admittedly can be an important element in the successful completion of some cases, old fashioned and in-person surveillance simply cannot be beat. And for that, you need a serious Private Detective.


Either way, GreenVets Licensed Professional Investigators are highly trained in surveillance and are prepared to expertly and covertly track the subject of your case. Our personnel have traveled a wide range of the state conducting surveillance in all of North Texas and beyond. This includes all parts of Collin County from our office in Plano.

Our company fields both male and female surveillance teams and can mix them as required for any scenario. When working your case, our surveillance specialists are only working for you and will have no other assignments distracting them from the task at hand.

We live in the information age and private companies now gather unimaginable amounts of data on each and every person in the United States. For some, this has led to the idea that a database search and internet search can produce a tidy package on a subject and the case is complete.

Surveillance 1

This couldn’t be further from the truth. Technology has enabled investigators of all kinds to decrease the time it takes to work a case and produce better results; however, the rubber still meets the road and a human actually has to go and confirm or deny what the computer says.

Since several members of our firm are former Counterintelligence Special Agents, we call this process working on Human Intelligence (HUMINT). Human Intelligence, when combined with the outstanding technology we have available to us, produces Actionable Intelligence. This is information that leads to solving or completing a case. It’s information our clients can and do count on.


Surveillance is typically far removed from the picture most people have from watching movies and television shows. Surveillance is hard work and involves long hours. These long hours can range from intense action to extreme boredom, but it’s our job to deliver results every time. Not only that, but surveillance can be quite dangerous at times and most Private Investigators have interesting stories about their operations in the field.

While surveillance is useful in a wide range of case types, it can be especially important in the following cases:

Through advanced tradecraft employed in our surveillance, you will receive high quality written reports, photographs and video on the subject of the investigation. The methodology we employ during our surveillance and the collection of this information ensures it can be used as evidence in civil or criminal proceedings as required.

Surveillance 2


Our surveillance teams are in constant contact with headquarters to both send and receive updates through real time case management solutions available to our firm. GreenVets employs analysts who take large volumes of data from electronic sources and combine this with our high quality human intelligence from field operations to create a comprehensive case file for our customers.

We have conducted both small and large scale surveillance operations in permissive and hostile environments around the world. So whether you need surveillance on a subject in Allen, McKinney, Frisco, the Streets of Dubai or Addis Ababa, Ethiopia, you can rely on GreenVets.

Please contact us immediately via phone or e-mail for your free consultation with a Licensed Professional Investigator. We are available 24/7 to provide support, even in emergency situations. From our Headquarters 25 minutes outside of McKinney and our second office in Plano, GreenVets can provide exceptional investigative services across North Texas and beyond. In addition to the two cities we have offices in / near, we serve Addison, Carrollton, Frisco, Allen, Richardson and The Colony; however, please call us for any North Texas County or locations in other areas of Texas.
