Through a joint venture named In-YS (In Your Shoes), Riedel Communications collaborated with referees Patrick Kessel and Nicolas Winter to develop RefCam. Their partnership ensured that the camera system was designed with a deep understanding of referees' needs and concerns regarding the use of such technology.

RefCam comprises a head-mounted camera integrated with a transmission system. Because the headgear is ultra-lightweight, weighing just 6 grams, it is barely noticeable for the wearer. The system is available in live and record-only versions, and it features a mute and shutdown function for the microphone to ensure privacy for the referee using the system.

The footage captured by RefCam during the Bundesliga match was featured in the 30-minute program “Referees Mic’d up – Bundesliga,” produced by DFL Digital Sports. This program, aired on March 12, was distributed to both national and international media partners, offering unprecedented insights into the world of soccer officiating. Approval to use the RefCam system was granted by the International Football Association Board (IFAB) and in close coordination between DFB, DFL, and the participating clubs. While Riedel Communications used the record-only version of RefCam during this unique use case, the company has already demonstrated the system’s ability to produce broadcast-quality images during various events with national and international leagues.

Looking forward, RefCam is set to be a prominent offering from Riedel's Managed Technology division, which specializes in delivering custom-engineered technologies complemented by comprehensive support from Riedel's team of qualified engineers. This division previously played a pivotal role in designing a reliable communication infrastructure for Bundesliga referees, showcasing Riedel's commitment to enhancing sports broadcasting through technological innovation.
