When protecting sensitive information is critical to your success, the OSCOR provides the most automatic, reliable and cost effective capability on the market. OSCOR is a complete eavesdropping detection package that is portable and programmable.

OSCOR is a microprocessor controlled counter surveillance system with a custom designed built-in spectrum analyzer that can operate automatically storing all encountered signals in memory for later review. Designed to detect all major types of audio and video RF transmitters, including carrier current and infrared. OSCOR is the only product that protects your environment 24 hours a day.


  • Automatic Threat Correlation. The patented OSCOR correlator provides signal classification by correlating the demodulated audio of a received signal to the ambient noises of an environment.
  • Automatic Signal Scanning and Logging. Only the OSCOR provides an automatic solution to rapidly logging and classifying all the signals of your environment. A quick reference guide provides a single chart that completely defines the programming process.

  • Sonic ranging and triangulation to pinpoint bug locations. Using the Patented Threat Locating System, a bugging device can be readily found with no destructive searches. The Triangulate and Locate option uses sonic ranging to locate a threatening microphone.
  • The OSCOR provides detailed signal analysis capabilities with a complete built-in suite of audio demodulators and IF bandwidth selections. The audio demodulators include FM wideband, FM narrowband, AM wideband, AM narrowband, Sub-carrier, Single Sideband, and IF bandwidths 250 kHz, 15 kHz, and 6 kHz.
  • Built-in video monitors display images received on transmitted signals for protection against covert video transmitters. Supported video formats include NTSC, PAL, and SECAM. This feature is not included in the basic unit
  • Built-in automatically switched antenna array. Foldout antenna panel automatically selects the proper antenna with no connections required. Pre-amp provides maximum sensitivity for the proper input. No un-reliable cable connections or mismatched antenna inputs.
  • Built-in printer for hard-copy printouts. The OSCOR built-in thermal printer provides a user with the ability to generate printouts of important sweep data.
  • Removable Program chip for ease of upgrading software. When a new OSCOR upgrade comes out, simply contact REI to request a new program key.
  • PC Interface and Remote Control of the OSCOR. The OSCOR PC interface software provides the capability to create permanent database profiles of sweep environments, generate professional reports and graphs. Modem option that provides for control of the OSCOR from a remote location using standard telephone lines.

OSC-5000 Advantages

  • Portable complete package of countersurveillance test equipment. Complete unit is the size of a large brief case and can be easily carried on a plane, bus, or car as hand-carry luggage.
  • Programmable Automatic Mode that continuously scans all bands and silently detects eavesdropping devices. The OSCOR can be used around the clock to monitor an environment without an operator present.
  • Signal Database Storage provides ability to store, retrieve, and analyze signals that are automatically logged by the OSCOR. New software will provide the ability to develop signal databases for each sweep location as well as performing future signal comparisons.
  • High Sensitivity Digital Synthesized Receiver scans Radio Frequency (10KHz to 3GHz),(3-21GHz by using the MDC-2100 down converter), carrier current (10KHz to 5 MHz) including and infrared (850nm to 1070nm / 10KHz to 5 MHz).
  • Built-in Demodulators and Bandwidths: Demodulators include AM, FM, SSB, Sub-carrier, and video(available as an option). IF bandwidths are built-in and programmable and include 6Khz, 15KHz, and 250Khz.
  • Antenna Array: All OSCOR input antenna's are built into the case and are automatically switched.
  • Acoustic Correlator utilizes passive sound pattern matching to automatically detect and classify a listening device even when the OSCOR is running automatically (un-manned).
  • Strip Chart Plotter built-in the OSCOR to provide hard-copies of spectrum profiles, signal database information, correlation printouts, etc.. Printer functions as WYSIWYG(What You See Is What You Get) operation by printing any information that is displayed on the screen.
  • Video Receive and Display Capability. Optional feature provides ability to receive NTSC, PAL, and SECAM video formats to provide detection of transmitted video signals including covert chip cameras that are increasingly proliferated.
  • Triangulation and Location System*. Patented system that allows the user to pin-point the location of an eavesdropping device without the need for destructive and time consuming searches
  • Computer Interface to provide signal database utilities and remote control of the OSCOR.
