AutoHarness

Monitor, protect, and diagnose your vehicle — from anywhere.

AutoHarness turns your Android device into a powerful onboard computer, security system, and diagnostic tool. Whether parked or on the road, AutoHarness keeps you connected to what matters.

Real-Time OBD-II Diagnostics
Plug in any ELM327 adapter (Bluetooth or USB) and instantly access live engine data. Watch RPM, speed, throttle position, fuel pressure, coolant temperature, and 50+ sensor parameters update in real time. Read and clear diagnostic trouble codes (DTCs) with plain-language descriptions. View your VIN, detected protocol, and adapter voltage. AutoHarness automatically detects your vehicle's protocol and enumerates supported PIDs so you see exactly what your car can report.

Smart Vehicle Security
Arm AutoHarness and walk away. The app monitors your vehicle's accelerometer, GPS, microphone, compass, and barometer simultaneously. If someone bumps your car, opens a door, or moves your vehicle, the alarm fires instantly. Sensitivity is configurable per sensor — dial it up or tone it down to avoid false triggers. Get push notifications straight to your phone when something happens.

IP Camera Integration
Connect IP cameras (RTSP, MJPEG, or JPEG) for visual monitoring with built-in object detection. AutoHarness identifies what triggered your alarm — a person, an animal, a vehicle — not just that something happened. Stream and cache footage directly through the app.

DVR Recording & Playback
Continuously record from connected cameras and microphones into a rolling on-device DVR. Browse any time window, scrub through cached recordings with frame-accurate seeking, and export clips straight to your device's media library as standard MP4 files.

Multi-Device Communication
AutoHarness runs a local server that lets your devices talk to each other. Monitor a vehicle from a second phone or tablet on the same network, or connect remotely through the cloud. All sensor data, camera feeds, and alarm states sync across connected devices in real time.

Live Data Pipeline
Every sensor reading flows through a real-time property system with configurable polling intervals. Subscribe to the data you care about and watch it update live. Engine data, GPS coordinates, compass heading, sound levels, camera detections — all streaming as they happen.

Audio Analysis
Advanced sound processing detects unusual noise patterns using FFT analysis and configurable biquad filters. The app distinguishes between ambient background noise and potential intrusion sounds, reducing false alarms while catching real threats.

Built to Run in the Background
Critical services run in dedicated processes so monitoring continues reliably even when the screen is off or other apps are in the foreground. The alarm system, sensor polling, and camera monitoring all operate independently — your vehicle stays protected without keeping the app open.
