Count Anything In A Video Feed With Visual Counter by Gravio: People In A Queue, Parked Cars, Products On A Shelf. You Name It.

This Visual Counter is based on Gravio, a versatile Edge Computing IoT Platform.

Gravio is a versatile, easy to use Edge IoT system for creating smart spaces in an simple, fast and reliable way. Without any programming knowledge.

Most systems rely on a Cloud system. But Gravio is Edge based, meaning there is no data leaving the premises, no dependency on network or privacy, if you don’t want to.

Count People or Queue Lengths

We have off-the-shelf AI models that can cound people in the picture. Clients use it to measure congestion or queue lengths.

Train Your Own

You can train your own AI models to detect and count anything you want, depending on how well it can be recognised.

ONVIF Standard

Gravio is supporting the ONVIF standard, the most common security camera system standards. This makes it easy to plug the systems in.

Easily To Combine With Other Sensors

Do you want to combine the counting module with other sensors such as motion, door or even button sensors? It’s built-in and ready to go.

A wide and flexible range of sensors available additionally

Thanks to the Gravio Platform, this Visual Counter also supports a broad range of other sensors on top of the visual recognition. That reaches from vibration, temperature, humidity, magnet, motion or buttons all the way to CO2 sensors.
The sensors, actions and APIs can be put together in an almost unlimited amount of combinations. Your creativity is the only limitation.

Get started

Available Sensors and APIs

These are the sensors and APIs you can use. Now the creativity is yours.

Temperature Sensors

Detect the temperature in a room, for example to switch on or off the air conditioning.

Humidity Sensors

Detect humidity in rooms and trigger ventilation accordingly.

Magnet Sensors

Detect if doors or windows are open or closed.

Motion Sensors

Detect if there is a moving person in a room or not.


Make your room interactive by connecting it to buttons, for example to book the room.

Vibration Sensors

Detect if something has been moving, stopped moving or was falling on the floor.

Double Buttons

What others say

What people say about the Gravio based smart room system.

Gravio is the best solution to deploy IoT solutions with the ThinkCentre Tiny, ultra-small desktop computer. This combination could enable edge-based IoT services with a small start and easy-to-use friendly GUI.

Ryota Motojima, Product Manager, Lenovo Japan

Gravio and its sensors are a very good product to get started with IoT. It is easy to make use of sensor data such as temperature and occupancy or integrate with the cloud and AI.

Norimitsu Katsuragi, Nisseicom Ltd.

I was pleasantly surprised by how reliably Gravio can publish our waiting list queue length to our website. We will definitely continue using it even after Covid-19 has converged.
