Harry Lennard: Head of Refereeing, Genius Sports


3rd July 2026

MONDO | STADIA spoke with Harry to explore how semi-automated offside technology is being deployed across some of the world’s most demanding stadium environments. From the logistics of installing 30 cameras across 20 architecturally distinct Premier League grounds to the mesh tracking data that underpins every decision, Harry discusses the operational realities of rolling out SAOT at scale. He also addresses the fan experience question that has dogged VAR since its introduction —and makes the case for why speed, accuracy and in-ground clarity are no longer competing priorities.

SAOT needs 30 cameras installed in every stadium – how does the placement and calibration of those actually work on the ground, and who owns that process at each venue?

Semi-automated offside technology (SAOT) is one of many systems that runs off GeniusIQ, our data and AI platform. When we partner with a new league, we align closely with them and each of their teams to install our cameras in every stadium. These cameras capture a wealth of official tracking data from each game, which feed into GeniusIQ as a central system of intelligence. 

Once GeniusIQ is deployed in a league, we can power everything from semi-automated offsides to data-driven coaching solutions and immersive fan experiences.
