Pi 5 OpenCV Face Recognition Door Kit with Raspberry Pi 5 + Camera
Build Your Own Face Recognition Door Lock with Raspberry Pi 5 and OpenCV
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine walking up to your door and having it unlock automatically, recognizing only the faces you’ve authorized. This kit turns that idea into a working prototype you build yourself, using a Raspberry Pi 5 and a Pi Camera Module 3. The system captures a live video stream, runs OpenCV-based face recognition, and triggers a relay to unlock a door when a known face is detected with 95% confidence.
What You'll Build
You’ll assemble a complete face-recognition access control unit. Mount the camera at your entryway, wire the relay to a solenoid lock or electric strike, and configure the software to enroll faces and grant access only to those registered. The final build functions as a real-world smart lock demo—perfect for college projects, hackathons, or your home lab.
What You'll Learn
- Capture and process images using the Pi Camera Module 3 and OpenCV in Python
- Train a face recognizer (LBPH or deep learning model) and set confidence thresholds
- Interface a 5V relay module with the Raspberry Pi GPIO to control external door hardware
- Integrate status LEDs and protective diodes to build a robust, presentable prototype

Who This Kit Is For
B.Tech students in ECE, EEE, or CSE can present this as a major/minor project or Smart India Hackathon entry. CBSE Class 11-12 students exploring AI and IoT get a concrete, working model. ATL Tinkering Labs and coaching institutes looking for a structured computer vision activity will find the included AI companion and our pre-flashed SD card invaluable.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to start a conversation with the AI companion trained on this specific kit. It guides you step by step, and if you need human help, our WhatsApp support team is available too.
How accurate is the face recognition, and can it work in low light?
The OpenCV recognizer uses a confidence threshold of 95% to avoid false unlocks. The Pi Camera Module 3 has autofocus and works well in indoor ambient light; you can add external IR LEDs for night operation with minimal changes.
Does the kit include the door lock mechanism itself?
No — the relay provides a 5V trigger signal. You connect it to your own electric strike or solenoid lock (common in college labs). The kit includes wiring diagrams and precautionary diodes to protect the Pi.
Can this be used for a final-year project or hackathon?
Absolutely. The system covers image processing, GPIO control, and Python scripting — core areas for IoT and embedded systems courses. Multiple students have showcased similar builds at Smart India Hackathon with excellent feedback.
Pi 5 runs OpenCV face recognition on camera. Relay unlocks door on known face with 95% confidence.
