CATrak Technologies, Inc. has addressed the widespread theft of catalytic converters in the United States, Canada, and Europe with the only solution that alerts of a theft in progress. Thefts of catalytic converters in commercial and consumer vehicles reached an all-time high in 2021, with many large cities reporting over 500% increases year over year. California alone expects an increase in thefts of catalytic converters to triple over the next two years. Los Angeles Catalytic Converter theft increased over 400% in 2021, Quebec 700%, and 338% globally. Current efforts to stem the surge in thefts are woefully inadequate and ineffective, with the most common prevention guidance to “park in a garage or well-lit areas near high traffic”. Other theft prevention techniques include hardware such as metal plates, cages or clamps, which are easily dismantled by the saws used by thieves. CATrak is affixed directly to the catalytic converter using proprietary methods. When tampered with, a remotely mounted 140 dB siren is activated concurrent to cellular, which then sends an SMS text alerting anyone nearby, compelling the thief to drop and run, thus preventing the majority of thefts. Should the converter be taken, a GPS tracking function is activated which alerts the authorities and the owner via the CATrak app to facilitate recovery and apprehension of the thief. No etching or painting necessary, CATrak gives your catalytic converter an identity once paired to the vehicle's VIN and registration.
