Everything Your BYD Needs

Built specifically for BYD vehicles with deep system integration

GPU Zero-Copy Pipeline

Revolutionary architecture that processes video entirely on the GPU. Camera frames go directly to GPU texture → composition → hardware encoder, never touching the CPU.

<28% CPU Usage
~150MB Memory
<3s Boot Time
Market First

Proximity Recording

Uses BYD's 8 parking radar sensors to detect approaching objects. Records pre/post event clips only when something gets close — saving storage and resources.

  • Configurable trigger levels (Yellow/Red)
  • Pre-event buffer (captures before trigger)
  • Post-event duration (configurable)
  • 500ms debouncing to prevent false triggers

Real-time Performance Monitor

Dedicated dashboard showing CPU, GPU, memory usage, and battery voltage. Know exactly what resources your system is using.

Advanced Sentry Mode

24/7 surveillance with motion detection and AI object recognition. Keeps your vehicle protected while parked.

ISP Blocklist Bypass

Browse internet via BYD's built-in SIM card, bypassing ISP restrictions. No dedicated WiFi hotspot needed. Optional paid feature as server costs grow.

ADB Shell Runner

Built-in terminal for developers. Run shell commands, check process status, view logs, and debug directly from the app.

Remote Viewing

Watch Your Car From Anywhere

Three flexible options for remote access — choose what works for you

Local Network (LAN)

Easiest

Connect when you're on the same WiFi network as your car.
