The CBF officially implements semi-automated offside in the Brazilian Serie A, bringing cutting-edge technology to optimize refereeing precision in upcoming rounds.
Semi-automated offside technology (SAOT) arrives in the Brazilian Serie A with the mission to reduce error margins and speed up decisions on crucial plays. After rigorous tests conducted in Brasileirão U-17 matches, the CBF confirmed that the feature will be operational in all Serie A matches starting from Round 20, marking a new phase for VAR in the country.
Unlike the system used by FIFA in World Cups, the solution contracted by the Brazilian entity from the company Genius does not require the use of internal sensors in the ball. Instead, the model is based on a robust system of high-performance cameras.
How the Technology Works
The system operates with approximately 30 state-of-the-art devices spread across the stadiums, capable of recording in 4K at 100 frames per second. With this data, software creates a digital replica of the field and players, allowing referees to identify the athletes’ position at the moment of the pass with millimeter precision.
In stadiums like Arena da Baixada, for example, the devices were installed in pairs in the four corners of the roof, ensuring full coverage of the pitch. This infrastructure allows for instant virtual lines to be drawn, providing greater legal and sporting certainty for video assistant referees.
The Impact on the Brasileirão
The adoption of the system aims to eradicate doubts surrounding tight offside calls, one of the most debated points in national refereeing. The mandatory installation of the system in stadiums hosting Serie A matches reinforces the CBF‘s commitment to modernize the spectacle and ensure that the on-field outcome is determined solely by the players’ merit.
With the official debut confirmed for next Saturday, clubs and fans are eagerly awaiting the real effectiveness of this tool. The expectation is that analysis time will drop considerably, avoiding lengthy stoppages and increasing match dynamism.
For clubs looking to elevate the level of their facilities, this move also serves as an incentive. Palmeiras, in fact, has already anticipated this by securing the service for Arena Barueri, ensuring that the technological standard is maintained regardless of home-field advantage. The era of digital precision has arrived on Brazilian pitches, promising fewer controversies and more sporting fairness for the final stretch of the championship.
