Surveillance Techniques

Surveillance is a cornerstone of private investigation. It involves monitoring a subject’s activities to gather evidence and understand their behavior. At SA Mercantile Investigation Services, our team is skilled in various surveillance techniques:

  • Static Surveillance: This involves monitoring a location from a fixed position. Our investigators stay concealed and observe the subject’s activities, often using vehicles or other cover to remain undetected.
  • Mobile Surveillance: When the subject is on the move, our investigators follow them to observe their actions. This requires excellent driving skills and the ability to remain inconspicuous while maintaining visual contact with the subject.

Infrared / Night Vision Cameras

Gathering evidence doesn’t stop when the sun goes down. Infrared and night vision cameras are essential tools in our arsenal, allowing us to conduct surveillance in low-light or no-light conditions. These cameras use infrared technology to capture clear images and videos, ensuring that we don’t miss any crucial activity regardless of the time of day.

Covert Surveillance

In many cases, the success of an investigation hinges on the ability to conduct surveillance without the subject’s knowledge. Covert surveillance is a technique that involves using discreet methods and equipment to monitor a subject’s activities. This might include hidden cameras, undercover vehicles, or investigators blending into the environment. The goal is to gather evidence without alerting the subject, which could compromise the investigation.

Background Checks and Record Searches

Understanding the history and background of an individual is often crucial in private investigations. Background checks and record searches are techniques we use to uncover relevant information about a subject. This process might include:

  • Criminal Record Checks: To determine if the subject has any past criminal activity.
  • Employment History Verification: To confirm the subject’s job history and qualifications.
  • Financial Background Checks: To assess the subject’s financial stability and identify any potential red flags.

Database Searches

In the digital age, much of the information we seek is stored in various databases. Our investigators have access to a wide range of proprietary and public databases, enabling us to gather comprehensive data on subjects. These searches can provide insights into:

  • Property Records: To uncover ownership and transaction history.
  • Social Media Activity: To gather information on the subject’s online presence and interactions.

Skip tracing

Skip tracing is a specialized technique used by private investigators to locate individuals who have gone missing or are intentionally avoiding detection. At SA Mercantile Investigation Services in Adelaide, our experienced team employs a combination of investigative skills, advanced technology, and access to extensive databases to track down individuals.
