· Smart counting sensor
The world's most compact 3D sensor, with on-board AI: >98% accuracy, passenger classification and origin–destination matrices. Without ever identifying anyone.
Certified accuracy, day and night, thanks to 3D stereoscopic vision and infrared.
Passenger classification and origin–destination matrices, computed directly on board the vehicle.
95 × 59 × 32 mm and 250 g: twice as compact as competing sensors.
EN 50155, ITxPT, GDPR / CNIL. Plug & play, PoE 48 V or 9–75 V DC, for new vehicles and retrofits alike.
The smallest counting sensor ever designed — twice as compact as competing sensors, shown here next to a €2 coin for scale. It is installed above each door, single or double, at heights from 1.90 m to 3.50 m: a single sensor per door, unobtrusive in every vehicle.
Powered by artificial intelligence
The AI tracks flows anonymously from one stop to the next and automatically rebuilds your O–D matrices: who boards where and alights where — data that field surveys used to take months to produce.
The sensor distinguishes passenger types so you can size your services precisely — classes configurable to your network.
A passenger hesitating on the step isn't counted twice. The AI tells a genuine crossing from a back-and-forth.
The neural network gets richer with every update deployed via the cloud: your fleet improves without changing hardware.
The sensor aggregates its own data — time-stamped counts, position, AVL information — and sends it directly through a router already on board. No intermediate equipment is needed.
WEBREATHE is listed with the CATP — the French public transport purchasing centre.
The range 
Sensors, computers, switches and antennas: a complete, compact, certified chain — from sensor to data, for road and rail alike.
135° wide-angle 3D stereoscopic vision, certified accuracy above 98%, day and night counting. One sensor per door, single or double — U-turn detection and 4 counting modes.
The computer-router for road networks. It aggregates counts, geolocates them and transmits them over 4G — for new vehicles and retrofits alike, with SIM card pooling.
The most powerful rail computer WEBREATHE has ever designed: 8 Ethernet ports including 4 PoE, AI video analysis for up to 8 cameras, 12–160 V DC power supply.
The on-board switch that connects and powers everything: 4 PoE ports (120 W), up to 1000 Mbps, zero configuration, daisy-chaining for articulated vehicles.

Two tri-mode antennas (4G+, GNSS, Wi-Fi): PUCK, low profile for buses and coaches; SHARK, high performance for trams and trains, compliant with EN 50155 and EN 45545-2.
Managed 16-port M12 Ethernet switch: the Gigabit backbone of the densest on-board architectures — counting, CCTV, passenger Wi-Fi and ticketing on a single network. Made in Germany, compliant with EN 50155 and ITxPT.
Tests carried out by the independent laboratories EMITECH and EFECTIS.
