Talk to a Professional Private Investigator - One solution for all your investigative services

Surveillance Service

Stryker Investigation Services Inc. One solution for all your investigative services since 2000 


Stryker conducts surveillance at the clients request for the purpose of monitoring a particular subject behavior or activities. Typically surveillance is done covertly or at a distance by means of electronic equipment, usually a camcorder or a covert video recorder. Undercover and covert surveillance service are used by private investigation agency and governments as a means of gathering intelligence without an individual’s knowledge. Surveillance can be “static” or “mobile” and can involve one person or a team. The purpose of the surveillance program is to provide professional investigative, counterintelligence, and Stryker investigators are trained to carry out a wide variety of assignments at locations throughout the US.



Surveillance – Monitor the subject’s activities and document all information and make it available immediately.

Investigations – Authenticate and confirm the facts of loss – determine coverage, scope of loss, and validity of claim.

Frauds – Quickly identify suspicious claims, monitor red flag markers, and scrutinize all suspicious claims and refer for investigative services.

Database – Administrators have daily case activity readily available and can depend on accurate updates and actionable information – immediately

Corporate Risk – We work directly with the examiners, attorneys and management to conduct the services around key or significant claim activity or determine patterns of loss from embezzlement.

State of the Art Technology – We developed and produced sophisticated real-time investigative software for on demand results.



There are two fundamental types of surveillance, covert (without their knowledge) subrosa a term used by insurance fraud industry to describe covert field surveillance,  and overt or (open and obvious) from this foundation emerge sub-categories such as counter surveillance, inverse surveillance, computer surveillance and recent developments of electronic media and the internet, computer databases.  

Surveillance Bugs:

Electronic covert listening devices commonly referred to as “bugs.”  There are five different kinds of bugs: acoustic, ultrasonic, RF (radio frequency), optical, and hybrid. Acoustic, ultrasonic, RF, and optical bugs are distinct, specific types of bugs, and hybrids are simply a combination of any two types of bug. An acoustic bug, the most low-tech of all bugs, can be any non-electronic device used to observe communication with the naked ear. Examples of acoustic bugs include drinking glasses, stethoscopes, or rubber tubes, either pressed against or inserted into an area in which there’s a sound leak. Ultrasonic bugs use a technique by which they gather sound, convert it into an audio signal above the range of human hearing, then allow it to be intercepted and converted back to audible sound. An RF bug can be placed in an area and/or inside a device, to transmit audio via radio frequency. RF bugs are quite easy to detect, but they are inexpensive and difficult to trace back to the person who planted it. Optical bugs convert sound into an optical pulse or beam of light. Because they are highly expensive and very easy to detect, optical bugs are rarely used. Examples of optical bugs include active and passive laser listening devices. Surveillance devices, or “bugs”, are not really a communications medium, but they are a device that requires a communications channel. A “bug” usually involves a radio transmitter, but there are many other options for carrying a signal; you can send radio frequencies through the main wiring of a building and pick them up outside, you can pick up the transmissions from a cordless phones, and you can pick up the data from poorly configured wireless computer networks or tune in to the radio emissions of a computer monitor. Bugs come in all shapes and sizes. The original purpose of bugs was to relay sound. Today the miniaturization of electronics has progressed so far that even TV pictures can be broadcast via bugs that incorporate miniature video cameras (something made popular recently during TV coverage sports events, etc.). conducted surveillance at the clients request for the purpose of monitoring a particular subject behavior or activities.
