Advanced Sentry Mode for BYD Vehicles

Download Alpha • Website • Discord • Features • Setup Guide

---

Free, open-source dashcam and sentry mode app built specifically for BYD vehicles with DiLink v3. All data stays on your device — no cloud, no accounts, no subscriptions.

Quick Start (Use Pre-built APK)

Download the latest APK from GitHub Releases and install it directly on your BYD head unit.

1. Prerequisites

• Ensure Wireless ADB is enabled on your device before launching the app.

2. Initial Configuration

1. Authorize ADB: On first launch, accept the ADB authentication prompt on your device screen.
2. Background Persistence: In Settings, ensure the "Disable Autostart" toggle is unchecked. This is critical for reliable background operation.

⚠️ CRITICAL: Hard Reboot Required After the first installation and initial run, you must hard reboot the device: Press and hold the Volume Down button for 5 seconds. Wait for the system to fully restart. This step is necessary to finalize the installation.

3. Network & Tunnel Setup

Option A: Dedicated Wi-Fi Hotspot (Recommended)

• Keep the Sing-box Proxy disabled.
• Directly enable your preferred tunnel (Zrok or Cloudflared).

Option B: Public / BYD SIM

• Toggle the "Public" switch at the top right of the dashboard.
• Go to Daemon View and verify the Sing-box Proxy Daemon is running.
• Once verified, enable your preferred tunnel (Zrok or Cloudflared).

Telegram Notifications Setup

1. Message @BotFather on Telegram → /newbot → follow prompts → get your bot token
2. Message @userinfobot → /start → copy your Chat ID
3. In OverDrive: Settings → Notifications → enter bot token & chat ID

Features

• Optimized Recording Pipeline — <28% CPU, ~150MB memory, <3s boot time
• Proximity Recording (Market First) — Uses BYD's 8 parking radar sensors to trigger recording only when objects approach. Configurable trigger levels, pre-event buffer, and 500ms debouncing.
• Advanced Sentry Mode — 24/7 surveillance with motion detection and AI object recognition
• Real-time Performance Monitor — CPU, GPU, memory usage, and battery voltage dashboard
• ISP Blocklist Bypass — Browse via BYD's built-in SIM card without a dedicated hotspot
• ADB Shell Runner — Built-in terminal for running commands, checking processes, and viewing logs
• Telegram Notifications — Instant alerts for motion detection, recording events, and low battery
• Recording Library — Calendar view for browsing and managing recordings

Remote Access

Three options for viewing your car's cameras remotely:

Local Network (LAN)

Access at http://<car-ip>:8080 when on the same WiFi. Zero setup, fastest streaming.

Cloudflare Tunnel

Access from anywhere via https://<random>.trycloudflare.com. No port forwarding, HTTPS by default. Video streaming can be slow due to Cloudflare limitations.

Zrok Tunnel (Recommended)

Free, open-source tunneling with no bandwidth limits at https://<your-share>.share.zrok.io. Best for video streaming.

Quick Zrok setup:

1. Sign up at zrok.io
2. Get your invite token from email
3. Enter token in OverDrive settings
4. Done — tunnel URL is auto-generated

Building from Source

git clone https://github.com/yash-srivastava/Overdrive-release.git

Set up signing by exporting these environment variables before building:

export KEYSTORE_FILE=/path/to/your/release.jks
export KEYSTORE_PASSWORD=your_password
export KEY_PASSWORD=your_key_password
export KEY_ALIAS=your_alias

Then build with Gradle:

./gradlew assembleRelease

VLESS Proxy Setup (Optional)

The ISP blocklist bypass feature uses a VLESS Reality proxy. The app ships with placeholder credentials — you need to supply your own.

1. Edit app/src/main/cpp/secrets/secrets.json and fill in your VLESS server details:

   "proxy": {
     "PROXY_SERVER_IP": "your.server.ip",
     "PROXY_SERVER_PORT": "443",
     "PROXY_UUID": "your-uuid-here",
     "PROXY_SHORT_ID": "your-short-id",
     "PROXY_PUBLIC_KEY": "your-public-key",
     "PROXY_SNI": "google.com"
   }

2. Encrypt each value using the helper script:

   pip install pycryptodome
   python3 generate_safe_enc.py "your.server.ip"

3. Replace the corresponding Safe.s("...") values in app/src/main/java/com/overdrive/app/daemon/GlobalProxyDaemon.java (lines 71–79).

4. Rebuild the app.

If you don't need the proxy feature, you can skip this — the app works fine without it.

Zrok Token Setup (Optional)

If you want to use Zrok tunneling for remote access, you need your own Zrok invite token:

1. Sign up at zrok.io and get your invite token from email
2. Enter the token in the app: Daemons → Zrok settings
3. If building from source, also replace YOUR_ZROK_TOKEN in app/src/main/java/com/overdrive/app/daemon/telegram/DaemonCommandHandler.java with your token (this is only used for the Telegram bot's /tunnel zrok command)

Privacy
