Dejero meets live stream challenge of Spanish Doñana triathlon

The event sees participants complete a gruelling 200km triathlon circuit in a unique natural setting

Dejero has announced that its EnGo mobile transmitters were used by sports production company Erizo.Media to live stream the demanding 130km ‘Desafio Doñana’ triathlon from beginning to end, across the remote Spanish Doñana National Park in Andalucía.


Taking place every Autumn, the event sees participants complete a gruelling 200km triathlon circuit in a unique natural setting, starting in the historic centre of Cadiz. This year, through Erizo.Media’s dedicated department, Akedis, the production team graduated, for the first time, from limited live content delivery using fixed checkpoint links, to a full live broadcast of the triathlon throughout the National Park. This progression is credited to Dejero’s EnGo mobile transmitters which were supplied by Dejero’s local partner, Ontario Solutions.

“Thanks to the Dejero EnGo and receiver, we were able to complete a high quality live transmission of this complex event, with very limited technical resources,” said Pedro Dueña, Production Manager at Erizo.Media. “The organisers are extremely satisfied with the result this year, and the number of viewers on the YouTube channel has grown significantly as a result.”


“This event is particularly challenging because of the long distances through unpopulated areas, where cellular reception may be weak,” continued Dueña. “Yet the EnGo transmitters performed impeccably, providing top quality, high-definiton pictures, even in those tricky areas, and made a rapid recovery after going through areas with no cellular coverage at all.”


The Erizo.Media deployment involved a 20-strong production crew, a number of fixed cameras, point to point links and two Dejero EnGo transmitters manned by two camera operators, who escorted the participants over 90km of bicycle route, 1km of the Guadalquivir river crossing and over 40km of running track. Content was streamed live to the official ‘Desafio Doñana’ YouTube channel from motorbikes, boats and 4x4s over a period of hours.

“Because of the Dejero EnGo mobile transmitters we were able to provide viewers with impressive live shots and unique participant interaction during the race,” continued Dueña. “And, as it was a live event, it was fantastic to be able to monitor signal quality through Dejero’s cloud-based management system so that we could rapidly switch camera feeds as the race progressed through areas of low coverage. The enhanced IFB audio support was also a bonus, as our operators were permanently connected to our production team and not dependent on a short-range intercom.”



EnGo is a versatile mobile transmitter that encodes high-quality video and transmits over multiple IP networks to deliver content with extremely low latency — even in challenging network conditions. It can be camera-mounted, vehicle-mounted, or worn in a backpack; and its modem modules and SIMs can be changed and switched for specific regional networks. EnGo is suitable for newsgathering, sports coverage, and live event broadcasting from remote locations, and while in motion.
