ChopSpotter uses an AI-powered acoustic sensor array to detect catalytic converter theft in real time — alerting you by SMS and email the moment a cutting event begins, not after the converter is gone.
A five-microphone array listens continuously for the acoustic signature of a cutting tool engaged with a metal exhaust pipe. No cameras. No line of sight required.
A five-element microphone array captures ambient audio from the monitored vehicle area at 22,050 Hz, with beamforming focused toward the protected zone.
Proprietary triple-pass harmonic separation isolates the sustained blade-vibration harmonics of cutting tools from background environmental noise.
An on-device Spectral-Classification network processes the acoustic signal in real time, identifying angle grinders, reciprocating saws, pipe cutters, and hacksaws.
A Bayesian evidence accumulator suppresses false positives before dispatching an SMS, email, and cloud event record the moment a genuine theft event is confirmed.
ChopSpotter is engineered for real-world commercial deployments — not laboratory conditions. It works where cameras can't see and alarms don't reach.
Continuous acoustic monitoring with on-device AI inference. No cloud round-trip required for detection — alerts dispatch within seconds of event confirmation.
Sound travels through and around vehicles. ChopSpotter monitors an entire parking area from a single mounting point — including vehicles obscured from camera views.
Alerts reach your phone and inbox before the thief has finished cutting. Include the time, location, and event classification in every notification.
A Bayesian evidence accumulator requires sustained classification confidence across multiple analysis windows before dispatching an alert — ignoring car doors, thunder, and passing aircraft.
WiFi is the primary alert path. A built-in cellular backup ensures alerts reach you even if the local network is disrupted — including by the thieves themselves.
Operates from a hardwired DC supply or a rechargeable LiPo battery, enabling deployment at any location in a parking area without dedicated power infrastructure.
ChopSpotter is designed for flexible installation across any vehicle fleet security environment — from open dealer lots to enclosed parking structures and mobile patrol operations.
Free-standing pole installation for open lots, dealership forecourts, and surface parking areas. Optimal acoustic coverage of a wide vehicle zone from a single central position. Hardwired DC or LiPo battery powered.
Perimeter or structural wall installation for enclosed parking structures, service bays, and rooftop decks. Directional beamforming aimed across the protected vehicle area. Ideal where a clear sightline to the lot exists.
Mobile deployment on an autonomous security patrol robot for dynamic lot coverage. ChopSpotter mounts directly to compatible patrol platforms, enabling continuous acoustic monitoring across large or multi-zone sites as the robot follows its patrol route.
All signal processing and classification runs locally on the device. ChopSpotter does not depend on a cloud server to make a detection decision — only to deliver the alert.
