Top Surveillance Techniques for Private Investigators

Physical Surveillance

Physical Surveillance

Physical surveillance is a fascinating aspect of the private investigation world. It involves observing people and their activities, providing valuable information for solving cases.

One technique often used in the industry is the "box method," where the investigator moves in a box pattern around their subject, varying the distance to avoid detection. It's an effective way of keeping a close eye on the subject without arousing suspicion.

Investigators may take turns following the subject, maintaining a safe distance while keeping the target in sight. This method is particularly useful in situations where the subject may be aware of potential surveillance and attempt to evade it.

Electronic Surveillance

Electronic Surveillance

Electronic surveillance is the use of technology to monitor and record a subject's activities. It has become increasingly popular in the private investigation field, providing valuable data while minimising the risk of detection.

GPS tracking devices are a prime example of this type of surveillance. These small gadgets can be attached to a subject's vehicle or belongings, allowing investigators to monitor their movements and establish patterns in their routine.

Audio recording devices, such as hidden microphones or wiretaps, are other popular tools.

These devices can capture conversations, providing insights into a subject's plans or intentions. It's important to note that the use of such devices may be subject to legal and ethical considerations, depending on the jurisdiction.

Hidden cameras are also used in electronic surveillance to monitor a subject's activities.

They can be placed in strategic locations, such as inside a subject's home, workplace, or vehicle, to gather valuable information. These cameras come in various forms, including nanny cams, covert body-worn cameras, or even cameras disguised as everyday objects.

Online Surveillance

Online Surveillance

This type of surveillance is becoming increasingly important given the widespread use of social media and the internet. It focuses on collecting information from online sources, such as social media platforms, forums, and public databases.

A common online technique involves monitoring a subject's public social media profiles.

By doing so, investigators can gather valuable information about the subject's habits, relationships, and whereabouts. This could include examining photos, posts, check-ins, or even the subject's list of friends and followers.

Private investigators also utilise online databases and resources to conduct background checks.

This might involve searching for criminal records, verifying employment history, or checking for property ownership. The information found in these searches can provide crucial insights into a subject's background, lifestyle, and potential motives.


In the ever-evolving world of private investigation, professionals employ a range of techniques to uncover the truth. Regardless of the method used, it's crucial for PIs to adhere to the law and respect the privacy of their subjects.
