Research Electronics International

What Research Electronics International does

Research Electronics International (REI), founded in 1982 and headquartered in Cookeville, Tennessee, designs and manufactures Technical Surveillance Countermeasures (TSCM) equipment used to detect electronic eavesdropping, illicit surveillance devices, and information theft. The company sells directly to government agencies, military organizations, law enforcement, and corporate and private security clients through a quote-based enterprise field sales motion. Its product suite spans five functional categories: RF detection (OSCOR Max/Blue/Green spectrum analyzers covering 10 kHz to 43 GHz, MESA 2.0 handheld analyzer, SWARM MESA continuous in-place monitoring system, ANDRE near-field receiver); non-linear junction detection (ORION HX Deluxe, ORION 2.4 HX, ORION 900 HX); telephone and VoIP line analysis (TALAN 3.0); audio countermeasures (PMK-8/PMK-2 voice masking kits, CMA-100 amplifier, ANG-2200 noise generator); and video and physical inspection (Hawkeye V3 HD borescope, Physical Search Kit, ultraviolet inspection tools). Bundled offerings such as the TTK Tactical TSCM Kit package these into deployment-ready field configurations.

REI's equipment incorporates proprietary patented and patent-pending technologies, including the SmartBars spectrum display, digitally correlated 2nd and 3rd harmonic response on NLJDs, an FFT algorithm for VoIP analysis, and auto-switching antenna systems performing 125 antenna switches per second on the OSCOR Max. Products are designed, manufactured, and supported in the United States and are sold as one-time capital purchases with a one-year warranty; FCC/IC and CE certifications are available for export. Revenue mechanics span hardware sales (primary), recurring accessories and consumables (antennas, probes, batteries, replenishment kits), and fee-based training services priced from $1,495 to $2,695 per student across Level 1-3 certification courses. Training is delivered at the company's 15,000 ft² dedicated Training Center (the largest commercially available TSCM training facility in the world) staffed by 7 full-time instructors, with on-site delivery available for customers unable to travel. A 36,000 ft² facility expansion announced in July 2025 will scale engineering, production, and training capacity.
