In or Out?

When it comes to precision and accuracy in tennis, line calls play a pivotal role in determining the outcome of a match. In the professional circuit, high-tech systems like Hawk-Eye have become the gold standard for electronic line calling systems. However, these sophisticated tools have largely remained out of reach for everyday players, leaving recreational, club, and semi-pro level matches to rely on human judgment, which, as we all know, isn't always flawless.

Relying on technology in tennis helps players enjoy accurate calls, ensuring a fair and stress-free experience. Zenniz sets a high standard for electronic line calling in tennis, offering an accessible solution for all types of matches, from casual games to competitive tournaments.

How It Works: Sound Triangulation and Cameras

Zenniz combines sound triangulation technology with four strategically placed cameras around the court. This combination allows us to accurately track the ball's movement and determine whether it's in or out with remarkable precision. It's like having your personal Hawk-Eye system right at your fingertips.

Microphones on the court detect the sound of the ball as it makes contact with the court, while the four cameras verify the exact landing spot from many angles. This technology ensures that even the fastest serves and the most challenging shots are accurately called in real-time.
