SmartNet transforms any goal into an interactive training environment. Target zones light up, every shot is tracked, and players and coaches get instant feedback on accuracy, power, and progress. SPINNOV was responsible for the full development of the system, from the LED net itself and the electronics and sensors inside it, through to the embedded software, signal processing, and the app that brings the data to life.
Client and Goals
SmartNet was created by an NCAA football coach who wanted a fundamentally better way to train attackers, one that could measure success, track improvement, and deliver instant feedback with every shot, rather than relying on observation alone. The goal was to build a system that could turn a standard goal into an interactive training environment usable by clubs, academies, performance centres, youth camps, and events.
The system needed to do three things simultaneously and in real time: light up dynamic target zones to direct where players should shoot, detect exactly where each ball made contact with the net, and generate the analytics that give players and coaches meaningful data on accuracy, power, and progress over time. SPINNOV was brought in to develop the entire technical system, hardware, software, and app, from the ground up.
Challenges
The core technical challenge was speed and synchronisation. A training system that delivers interactive feedback is only useful if that feedback is immediate, a delay between a shot landing and the system responding breaks the experience and reduces the coaching value. Getting the signal processing, sensor logic, and LED response to operate with low enough latency for real-time interactive use required careful architecture across the full hardware and software stack.
The physical hardware added further complexity. Developing the net itself, integrating LEDs and sensors into a structure that would survive repeated high-impact ball strikes in outdoor training environments, meant designing for durability as well as performance. The camera-based impact detection system had to be accurate enough to resolve precisely which zone a ball entered, under varying lighting conditions and shot angles, without adding latency to the feedback loop.
Tying all of this together into a system that a coach could set up and run without technical knowledge, and that delivered data clearly through a mobile app, required the hardware and software layers to be designed as a coherent whole from the start.
SPINNOV’s Solution
SPINNOV developed the complete SmartNet system. The LED net, designed and built by SPINNOV, lights up dynamic target zones during training sessions, giving players a visual target to aim for and changing the challenge in real time. A camera-based impact detection system tracks exactly where each shot enters the net, with fast signal processing ensuring the system registers strikes and responds with low latency.
The embedded software manages synchronisation between the sensor data, LED logic, and the SmartNet app, which delivers real-time shot feedback, heat maps, accuracy scores, and session reports to players and coaches on their phones. The full system is used by NCAA programs, elite clubs, and players across a range of levels and settings.
