Computer Vision Facial Recognition Door Variant 26 Kit with ESP32 + Relay
Build Your Own Face-Recognizing Door Lock with ESP32 and TensorFlow Lite
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 a door that unlocks only when it sees a trusted face — no keys, no cards, no passwords. This kit lets you build a standalone facial recognition access point using an ESP32-CAM module and TensorFlow Lite machine learning. You’ll train and deploy a face identification model, wire a solenoid lock driver, and add timestamped access logs, creating a prototype ready for real-world security experimentation in labs, offices, or research facilities.
What You'll Build
A complete door lock system that captures live video, runs on-device face recognition, and actuates a 5V solenoid via a relay when an enrolled face is detected. The DS3231 real-time clock stamps every access event, which can be stored on a microSD card for auditing. The circuit is designed on a prototype board and housed in a robust enclosure, giving you a deployable demonstration unit.
What You'll Learn
- Train and optimize a TensorFlow Lite face recognition model for the ESP32-CAM’s limited resources
- Interface an RTC module to create an event-logging access control system
- Design a stable power stage using a buck converter and bulk decoupling for noise-free camera operation
- Solder and assemble the full circuit on a prototype PCB, addressing EMI and mechanical stress

Who This Kit Is For
Engineers and researchers building edge AI security proof‑of‑concepts, B.Tech and M.Tech students in ECE or CSE exploring computer vision applications, and advanced hobbyists who want a reliable facial recognition door lock testbed. Also fits Smart India Hackathon teams developing access control prototypes and faculty looking for a ready‑to‑demonstrate lab exercise.
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?
The AI companion, reachable by QR code or WhatsApp, provides wiring guidance and software debugging specific to this facial recognition door lock — from resolving I2C conflicts to flashing the ESP32-CAM firmware.
Can I add multiple authorized faces?
Yes, the included SD card stores the model; you can train on several faces during enrollment and expand the dataset following the companion’s instructions.
Is this system secure against photo spoofing?
The kit includes notes on basic liveness checks (blink or movement inputs) but for production‑grade security you will need to implement additional anti‑spoofing layers beyond the scope of this project.
How long will the solenoid lock last?
The 5V solenoid is rated for thousands of cycles. We verify each unit before packing and our 7‑day replacement policy covers any manufacturing defects.
ESP32-CAM + TensorFlow Lite face ID model unlocks solenoid after recognising enrolled face.
