See what's
behind you.
TrailEye uses your phone's rear camera and on-device AI to detect, classify, and alert you to vehicles in your blind spot — including law enforcement, at any speed.
Three steps between you and awareness.
Frame
Mount your phone. TrailEye activates the rear camera and starts capturing the road behind you at up to 30fps.
Detect
On-device ML runs continuously, scanning for vehicle silhouettes, light bars, and distinctive features in real time.
Identify
Matched against a trained vehicle classifier. When a high-confidence match occurs — especially law enforcement — you get an immediate alert.
Built for the drive, not the dashboard.
Rear Camera AI
Uses your phone's existing camera. No extra hardware. Runs at 5–10fps on modern iOS and Android devices via on-device ML.
Instant Alerts
Audio and visual notification the moment a high-confidence vehicle match is detected. Configurable sensitivity thresholds.
Local Processing
No cloud. No subscriptions. No data sent to servers. All inference runs on your device's neural chip. Your location stays private.
Vehicle Classifier
Trained on police vehicle silhouettes, light bar shapes, and common patrol vehicle models. Updates via model downloads, not cloud streaming.
Always-On Background
Runs as a background process with minimal battery impact. Audio alerts still fire even when the app is minimized.
Night Mode
Enhanced low-light processing for nighttime driving. Light bars and reflective markings still detectable in dark conditions.
The signal is everywhere.
The awareness isn't.
Radar detectors scan for microwave signals. Crowdsourced apps depend on other users. But 1.2 million law enforcement vehicles drive US roads daily — and most have no radar signature until they're close enough to matter.
TrailEye changes that. A camera pointed backward, running AI, giving you the same situational awareness you've always had looking in your mirrors — but augmented.
The blind spot has a name.
It's called not knowing.
Every car has mirrors for what's ahead. Nothing handles what's behind you — until now. TrailEye brings real-time vehicle detection to your phone, so you always know what's following.
