How Can a Private Investigator Help You?

A private investigator is a professional trained in the art of conducting investigations, surveillance and gathering facts that are admissible in court. Like any professional, in the State of California, a license is mandatory in that certain qualifications, training and experience are required for licensing to protect you from those who do not have the knowledge or credentials to do the job properly. At Landmark Investigations, we frequently assist individuals, attorneys and businesses with a variety of legal, financial and personal problems with tasks such as surveillance, research and witness interviews. Essentially, we obtain information for our client and gather additional evidence and intelligence that will give you the ability to make sound knowledgeable decisions based upon facts.

Landmark Investigations specializes in surveillance and undercover operations.  We use a wide variety of professional-grade surveillance equipment to obtain the highest quality video and photographs.  Surveillance is one of the oldest and most common practices in investigative services.  But whether you’re gathering protective intelligence on a subject, or investigating an insurance fraud case, real-time, direct observation remains a useful tool.  Surveillance entails shadowing the suspect to obtain information.  This type of surveillance may be done in a variety of ways, including tracking on foot and following in a vehicle.  Surveillance should always be covert and undetected.  We utilize cutting-edge technology like body cams to observe individuals involved in cheating spouse investigations, as well as employee theft, misuse of company resources, policy violations, and much more.

We use covert, high-quality, 4K video cameras, remote-access IP camera technology, long-range lenses, and other cutting-edge technology to obtain the evidence our clients need for court, as well as peace of mind.  We also use unmanned surveillance when documenting activities at a particular address or other fixed location.  Unmanned surveillance uses stationary cameras that blend in with the environment to obtain discreet, effective, and legal video recordings.  They are designed to perform for long periods, three to ten days, and are a fraction of the cost of manned surveillance.

For private investigators, GPS tracking is an invaluable asset when it comes to surveillance.  Not only does it provide concrete evidence for private investigators, they are also safe, efficient, and cost-effective.  GPS devices, which are relatively small in size, can be affixed to the exterior of a vehicle without altering its appearance.  The device sends data to a host about where it has traveled using satellite technology.  We use advanced surveillance equipment in order to provide the most accurate information to our clients.  In addition, Tom was born and raised in Los Angeles, so he knows the area better than anyone else.

We conduct all surveillance activities in a professional and ethical manner.  We have conducted thousands of investigations and we keep raising the bar in terms of success and quality.  We also belong to several professional organizations and attend regular industry meetings to keep current on the newest trends and technology.
