Meilleure Caméra Bouton 2026

Après avoir testé toutes les caméras bouton du marché, nous avons fabriqué celle qui fonctionne vraiment.

Objectif 4K Autofocus

The camera module measures just 8mm in diameter, replacing a standard shirt button without any visible difference. The auto-focus system reads text as small as 8pt font from a distance of 30cm, capturing entire exam pages in a single frame. The lens adjusts to variable lighting conditions automatically, from bright fluorescent exam halls to dimly lit lecture theatres.

Moteur de Résolution IA

Unlike legacy button cameras that require a human partner on the phone to read and answer questions, our system uses an on-device AI solver. The captured image is processed through OCR and fed into a specialised solving model that handles mathematics, science, languages, and general knowledge. Answers are generated in under 3 seconds.

Oreillette Nano Magnétique

Answers are delivered through a 4mm magnetic earpiece that sits deep in the ear canal, completely invisible to the naked eye and undetectable by standard metal detectors used in exam venues. The earpiece connects via an encrypted GSM signal that bypasses Bluetooth scanning equipment commonly deployed in modern exam halls.

Comment se compare-t-il ?

Traditional button cameras from legacy brands require a human partner who watches the camera feed and reads answers aloud. This introduces a massive point of failure: the partner can misread questions, get distracted, or simply not know the answer. Our AI-powered system eliminates the human element entirely, providing faster, more accurate answers with zero reliance on another person.

Additionally, legacy cameras use Bluetooth connectivity, which is increasingly being detected by RF scanning equipment deployed in exam venues. Our GSM-based system operates on the cellular network, making it undetectable by Bluetooth scanners. Read our full legacy system review for a detailed comparison.

Spécifications Techniques

The button camera module captures video at 3840 x 2160 resolution (full 4K) at 30 frames per second. The auto-focus system covers a range from 15 centimetres to 3 metres, with a 65-degree field of view that captures an entire desk surface from chest height. The minimum readable text size is 8-point font at 30 centimetres, which covers all standard exam papers, textbooks, and printed materials.

The GSM neckband contains a 2000mAh battery providing approximately 4 hours of continuous operation, more than sufficient for any standard examination period. The neckband weighs 28 grams and sits flat against the body under clothing. The entire system charges via USB-C with a full recharge time of 90 minutes.

The AI solving engine processes captured images in 2 to 4 seconds from capture to answer delivery. It supports mathematics at all levels from GCSE through to university, sciences including physics, chemistry, and biology, modern languages, humanities subjects, and general knowledge. The accuracy rate across standardised test questions averages 99.2%.
