AI Face Detection Entry System Variant 2 Kit with ESP32 + Relay
AI Face Detection Door Lock Kit with ESP32-CAM & Relay — Secure Access Control
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 access point into a smart security checkpoint that grants entry only to recognised faces. The ESP32-CAM runs an on-device face detection model — no cloud dependency — and instantly triggers a solenoid lock the moment an authorised identity is verified. Every unlock event is logged with a real‑time timestamp, giving you a complete, auditable entry system for labs, private offices, or restricted zones.
What You'll Build
After assembling this kit, you’ll have a fully functional face‑detection door lock enclosed in the included box. Present a registered face to the camera and the solenoid releases; an unknown face keeps the door firmly shut. The OLED display confirms status, the DS3231 RTC timestamps every access, and the microSD module stores the full log for later review — a complete, offline security appliance you built yourself.
What You'll Learn
- Program ESP32-CAM for edge‑based face detection and recognition
- Integrate a solenoid lock and relay module for precise physical access control
- Implement event logging with a DS3231 real‑time clock and microSD storage
- Assemble and solder a permanent security system on a custom PCB

Who This Kit Is For
This advanced kit fits final‑year B.Tech ECE/EEE students building capstone security projects, Smart India Hackathon teams working on surveillance themes, and IoT professionals prototyping access control. It’s equally suited for research scholars at IIT, NIT, VIT, or BITS Pilani who need a concrete, working demonstration of on‑device face recognition with no cloud strings attached.
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 launch the AI companion. It works through the entire assembly and code, offering exact fixes. You can also message us on WhatsApp for direct engineer support.
Does this system need an internet connection to detect faces?
No. The ESP32-CAM runs the face detection model entirely on‑device. Once trained and programmed, it operates offline — no cloud dependency, keeping your entry system fast and isolated.
Can I enroll multiple authorised faces?
Yes. The companion tutorial shows how to capture and store multiple facial embeddings. You can register up to 50 faces on the microSD card and manage them easily through the OLED menu.
What type of door or gate can this solenoid lock secure?
The 5V solenoid is perfect for lightweight access points like server cabinets, lab drawers, or internal office doors. For heavy external doors, you can later upgrade to a 12V electromagnetic lock using the same relay logic with a simple power adjustment.
ESP32-CAM runs face detection model. Recognised face logs unlock event and triggers solenoid lock.
