Computer Vision Facial Recognition Door Kit with ESP32 + Relay
ESP32 Facial Recognition Door Lock Kit — Unlock with Your Face
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform any standard door into a secure, hands-free access point that opens only for enrolled faces. This kit combines the ESP32-CAM with TensorFlow Lite to run real-time face identification on-device, controlling a solenoid lock via relay. Ideal for prototyping smart office entry, lab access control, or personal security projects where traditional keys or PINs fall short.
What You'll Build
A fully functional biometric door lock that captures facial images, matches them against a locally stored database, and actuates a solenoid lock when a known face is detected. You’ll assemble the hardware on a prototype board, train and deploy a lightweight TensorFlow Lite model, and integrate an RTC for time-stamped access logging.
What You'll Learn
- Deploying TensorFlow Lite for real-time face recognition on an ESP32-CAM.
- Interfacing a 5V relay and solenoid lock with embedded GPIO.
- Using an RTC module to log access events with timestamps.
- Designing a stable power supply with buck converter and capacitor filtering for noise-sensitive camera modules.

Who This Kit Is For
Engineers and advanced hobbyists who want to fuse computer vision with physical access control. It’s built for B.Tech ECE/EEE final-year projects, Smart India Hackathon teams prototyping security solutions, and IIT/NIT/VIT students exploring on-device ML. ATL mentors and professional makers integrating biometrics into custom door locks will also find the pre-verified hardware and code a huge time-saver.
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 inside the box to access your AI build companion trained on this exact project. You can also reach our WhatsApp support for human guidance on tricky soldering or software issues.
Can I train the kit to recognize multiple faces?
Yes, the TensorFlow Lite model supports up to 5 enrolled faces. Enroll new faces by capturing images to the SD card and retraining the model using the provided Python scripts.
Does the kit include a mounting mechanism for the solenoid lock?
The enclosure box holds the solenoid and electronics securely. A basic strike plate and mounting bracket are included; you may need to adapt them to your specific door frame.
Will the recognition work in low light?
The ESP32-CAM’s built-in LED flash activates automatically in low-light conditions, and the model is trained on images with varied lighting to maintain accuracy.
ESP32-CAM + TensorFlow Lite face ID model unlocks solenoid after recognising enrolled face.
