TrailSense

TrailSense builds passive RF sensing hardware and software for large, remote properties that cannot be secured with traditional camera-based systems. Founded in 2024, their flagship device (the Meerkat) monitors three concurrent RF channels — wideband analog RF (20–4000 MHz), 802.11 WiFi 2.4 GHz, and Bluetooth Low Energy — to passively detect and fingerprint mobile devices crossing a property without cameras or active transmissions. The companion iOS/Android app fuses sensor data into a live tactical map, provides compass and turn-by-turn navigation to deployed units, and includes an on-device LLM AI assistant for real-time situation reports — all running locally with no cloud dependency. Target markets include large-acreage ranches, conservation reserves, industrial sites, and tactical/law enforcement deployments.

Properties larger than a single field of view — 500-acre ranches, fire roads, off-grid solar farms, wildlife corridors — cannot be effectively monitored with camera-based security systems that require line-of-sight, bandwidth, and staffing that simply don't exist in remote environments. Traditional security gear is designed for built environments, not vast outdoor perimeters with hundreds of access points.

TrailSense deploys solar-powered, IP67-rated passive RF sensor units (Meerkat) that detect and fingerprint mobile devices by listening to WiFi probe requests, BLE advertisements, and wideband RF bursts across hundreds of feet. A proprietary detection engine correlates multi-channel evidence and tracks devices across MAC randomization, delivering a live property picture to a companion app with AI-powered situation reports — all with no active transmissions and no cameras.

TrailSense has active field deployments across large-acreage ranches, conservation reserves, industrial sites, and tactical/LE use cases. The company is currently taking demo requests and building a regional waitlist for unit deployments.
