A Comprehensive Hardware Platform for the viSEN Autonomous AI Sensor

Client

VisionCraft, a Brno-based startup, uses self-learning AI to support the development and digitization of modern smart cities.

They have developed an innovative technology called viSEN, an intelligent sensor designed for the anonymous analysis of traffic and the movement of people in public spaces.

Assignment

At the start of our collaboration, the client had a working prototype, which, however, was built using commercially available development boards. While this solution worked for laboratory testing, it was completely unsuitable for long-term, stable operation in real-world conditions and, above all, did not allow for efficient and repeatable mass production.

Our task was to fully professionalize the design and create robust, market-ready hardware.

Call

The main challenge was to combine high computing power with the requirement for absolute data anonymity —the device must not store video footage, but only metadata about the trajectories of objects. The sensor had to be fully mobile, independent of a local network, and capable of reliable battery operation with overnight recharging.

A major technical challenge that had to be addressed was critical overheating of the system during intensive charging and high computational loads during the summer months. It was essential to ensure the stability of the electronics even under extreme temperature conditions without risking damage to the expensive battery.

Our solution

We designed and developeda unique, custom-built motherboard based on the NVIDIA Jetson platform, which serves as the brain of the entire device. We integrated camera modules, an LTE modem with a SIM card, and a GPS module for positioning, along with power supply cascades and an active cooling system, into a single unit.

A key feature of our solution is intelligent charging current control: the system monitors temperature in real time and, if necessary, slows down the charging process, thereby protecting both battery life and the stability of the entire system.

At the same time, we designed a custom mechanical structure that protects the internal components and, thanks to its well-thought-out layout, significantly speeds up assembly and installation by a technician in the field.

Result

The result of our work is professional, fully autonomous hardware that serves as the foundation for stable mass production of dozens of devices per year. Today, the sensor operates reliably in the field, where it transmits only anonymized data in real time with minimal data transfer requirements.

If an unexpected power outage occurs, the system automatically notifies administrators, thereby minimizing measurement interruptions.

Thanks to its modularity and professional board design, the entire solution is ready for future technological upgrades, such as the implementation of new battery types or more powerful processor modules, ensuring long-term protection of the client’s investment.
