SilentCamTrap – Catch Intruders with One Click (Then Auto-Shutdown Your PC)

SilentCamTrap is a personal security utility I built for one reason: to silently snap a photo of anyone who tries to snoop on my PC — and immediately shut the system down before they can do more damage.

Disguised as a harmless-looking executable game (PlayGame.exe), this tool uses a combination of C and Python to capture a webcam photo without any visible interface, store it with a timestamp, and then shut the system down — all in seconds.

🔍 How It Works

1. The user (you) runs PlayGame.exe — looks like an innocent game.
2. Under the hood, this executable silently runs a Python script.
3. The Python script:

• Activates the webcam.
• Takes a picture without showing any preview.
• Saves the image in a predefined folder (intruder_logs).
• Shuts down the Windows machine instantly.

⚙️ Tech Stack & Reasoning

• C: Used to create a lightweight, stealthy Windows-native executable (PlayGame.exe). It launches silently and looks legit — no console, no trace.

• Python: Handles the actual job of webcam capture and triggering the system shutdown via:

  • OpenCV for image capture
  • os.system("shutdown /s /t 0") for shutdown

🔁 Why both?
Python = fast development & rich libraries.
C = system-level disguise & native performance.

🛠️ Setup & Usage

Prerequisites

• Windows PC
• Python 3.x installed (for testing/dev)
• GCC (MinGW) for C compilation
• Python packages: opencv-python, pyinstaller

Steps

1. Clone or download the project.
2. Install dependencies:

   pip install opencv-python pyinstaller

1. Compile the Python script:

   pyinstaller --noconsole --onefile capture_shutdown.py

1. Move the resulting capture_shutdown.exe to the main folder.
2. Compile the C launcher:

   gcc trap.c -o PlayGame.exe

1. Double-click PlayGame.exe to test.

🔧 Customization

• Photo Save Location: Edit the folder variable in capture_shutdown.py.

• Make it Sneaky:

  • Rename PlayGame.exe to something that fits your use case.
  • Add a fake game icon using a .ico file and resource editing tools.
  • Store logs on an external drive, hidden folder, or encrypted volume.

🛡️ Security & Privacy Notes

• Data Privacy: No data is sent externally. All photos are saved locally.
• Ethical Use Only: This is designed for personal device security. Please ensure you're not violating any privacy laws or ethical boundaries.
• Transparency: Inform any shared users if this is active. (E.g., roommates, family)

SilentCamTrap

SilentCamTrap is a personal security utility designed to discreetly capture an intruder's photo using the webcam and then shut down the Windows PC immediately. It is disguised as a harmless game executable (PlayGame.exe) to trick anyone who tries to open your computer without permission.

---

How It Works

1. The user double-clicks the PlayGame.exe file, which looks like a normal game.
2. This executable is a small C program that silently launches a Python script in the background.
3. The Python script accesses the webcam, captures a photo without opening any preview window, and saves it to a predefined folder.
4. Immediately after capturing the image, the script shuts down the computer (shutdown /s /t 0).
5. The captured photo is saved with a timestamp in a folder (default is intruder_logs, but this can be customized).
