Ref cams

FIFA Club World Cup: The 2026 FIFA World Cup burst into life with a dazzling opening ceremony and a thrilling victory for co-hosts Mexico over South Africa. Yet, beyond the goals and glamour at the Mexico City Stadium, eagle-eyed fans quickly noticed something unusual strapped to the match officials: futuristic headgear that is changing how we watch football.

Linked to his microphone system, the prominent over-ear device gave the Brazilian referee Wilton Sampaio a sci-fi look. The equipment is a wireless referee communication system, known as 'Referee camera' or ref cam.

At this World Cup, referees are wired with three essential pieces of audio and visual gear: first the microphone; this keeps the main official in constant dialogue with their linesmen, the fourth official, and the Video Assistant Referee (VAR) team. It is also the tool used to broadcast live VAR explanations directly to fans inside the stadium.
