Retail Footfall Camera Kit with Raspberry Pi 4 + Camera
Build a Mobile Retail Footfall Camera Robot with Raspberry Pi 4
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Put a Raspberry Pi 4 and Camera Module 3 to work counting shoppers in a simulated retail environment. You'll write code that detects and tracks people at 25 frames per second, then mount the whole system on a two-wheeled robot that navigates aisles by following lane markings — the kind of analytics engine modern stores use to measure footfall and dwell time.
What You'll Build
A mobile robot that drives through a retail space, uses the Camera Module 3 to capture video, runs a TensorFlow Lite object detection model on the Pi 4, and logs every person who enters or exits a defined zone. The robot follows painted floor lanes to move autonomously, all powered by a 12V sealed lead-acid battery. You’ll walk away with a deployable people-counting system that outputs real-time dashboards via a local web server.
What You'll Learn
- Deploy real-time object detection on Raspberry Pi 4 with 25fps throughput
- Program lane detection algorithms using OpenCV and perspective transforms
- Interface DC geared motors through an L298N driver for precise robot control
- Integrate Pi Camera Module 3 for high-speed vision and on-device inferencing

Who This Kit Is For
Designed for final-year B.Tech students in ECE or EEE, Smart India Hackathon participants tackling retail or smart-city challenges, and anyone at IITs, NITs, VIT, or BITS who wants a production-grade computer vision project. The robot can serve as a base for advanced algorithms like multi-object tracking, re-identification, or edge-AI inference — exactly what goes into a standout resume.
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 chat with the AI companion; it knows every connection and line of code for this kit. Prefer a human? Send a photo on WhatsApp — we’ll reply within hours.
Is soldering required?
Yes, you’ll solder the capacitors and resistors onto a small prototyping board to stabilize the power supply and connect the L298N driver. The included soldering iron and solder wire make it straightforward.
How long does the battery last while running the camera and robot?
The 12V 3Ah SLA battery powers the Pi 4, camera, and motors for approximately 2 hours of continuous lane-following and people counting.
Can I adapt this to count vehicles instead of people?
Absolutely. The object detection model can be retrained for cars, cycles, or any object class; the lane detection and tracking logic remains the same.
Retail Analytics — Pi 4 + Camera Module 3 runs real-time lane detection and object tracking at 25fps for a robot car.
