A Higher-Level Physical Surveillance Service

Supporting Threat Management and Investigation Needs

Specializing in Sensitive and High-Profile Matters

Former FBI, CIA, Marine Corps & Navy SEALs

Established 1995

We are expert at covertly monitoring a subject deemed a high threat and video recording his or her activity and body behavior for security purposes and providing that information in real time from the field to the threat assessment expert. Sophisticated social media search engines, DMV accounts and proprietary databases are used to support our field operatives. 

Since it is imperative that the high threat subject not detect the surveillance, only surveillance operatives with five years or more experience conducting threat type cases are utilized. All surveillance team members perform surveillance full-time in the "private sector" and most have over twelve-years with our team conducting threat related surveillances in the Los Angeles area.

During our 19-years we have developed methods and skill-sets specific to surveilling high threat persons to ensure consistent mission success. Please contact us for a consultation on best practices for assigning and managing a physical surveillance vendor.

For 19-years, our full-time experts have conducted numerous high-profile surveillances and have consistently achieved our clients' goals by securing the needed information and evidence without being detected.

A successful physical surveillance is accomplished in most cases by overcoming obstacles that may prevent the field surveillance operatives from maintaining contact and line of sight with the person being surveilled. 

The surveillance team uses a variety of lawful tools to overcome the many obstacles encountered in the field. The Unmanned Aerial Vehicle (UAV) aka drone is one tool that we use.

An expert in UAV regulations and related law supervises any use of a UAV. A well established surveillance principle is that a person can never be watched if they are in a place where there is an expectation of privacy, and a person can never be recorded on video unless in full public view with no expectation of privacy.

Elite Physical Surveillance Team

"These guys are the special ops of the private investigation and security industries. Impressive." Security Consultant and Reference (retired LE; former Navy SEAL)


                        ` -                        

What we do: Elite surveillance operatives will covertly follow a person and record that person's public activity for lawful purposes.

Additionally, a seasoned case manager with several years of field surveillance experience will supervise the field operative(s) and provide the always needed support by looking up needed information from various proprietary databases and running DMV records when needed. 

Additionally, the case manager provides client with real time updates (when requested) that includes video or photos. Customized reports and updates are provided based on the client's needs.

Surveillance operatives will testify in court as to their observations and authenticate the recorded video evidence.

Recorded video evidence obtained in our surveillance-investigations regarding litigation has resulted in hundreds of favorable outcomes for our attorney clients and their clients.

Operatives conduct counter-surveillance for our client who is in the black Suburban en-route to Staples Center in Los Angeles. The stressed client was under a serious threat from a resourceful subject whose whereabouts were unknown at the time.

Another team of resourceful surveillance operatives, supported by proprietary databases, eventually located the threatening subject and he was put under 24/7 surveillance. The client was then at ease knowing we had subject under close watch.
