The era of real-time video is now, and it is transforming every industry. What began with entertainment and engagement now powers a diverse range of use cases worldwide. iGaming, betting, town halls, live corporate events, live commerce, live auctions, healthcare, mission-critical applications, and more. All of it is fueled by real-time, sub-second streaming.
Such business applications require much more than just having a camera and the willingness to start a transmission. It depends on sub-second video delivery that minimises delay, also called latency. Additionally, it involves consistency, stability, and reliability on a global scale, as businesses rely on 100% uptime to keep audiences engaged and operations running smoothly.
The market for real-time video is vast and growing fast, driven by demand for interactive experiences that connect people and businesses. The opportunity is significant, and expanding into new markets every day.

6- Healthcare and Telemedicine
From surgical training to multi-site team consultations, healthcare providers need real-time streaming for timely and coordinated patient care.
- Who it’s for: Remote monitoring teams, surgical trainers, diagnostic specialists, and healthcare providers delivering advanced care across borders.

For healthcare providers, this translates into better quality of care, faster decision-making, and the ability to scale advanced services across regions, delivering improved patient outcomes, reduced costs, and expanded access to care.
7- Industrial, Defense, and Public Safety
In industrial, defense and public safety, real-time video drives fast decisions, ensuring that decisions are made with the latest information.

- Why it matters: Operational readiness relies on real-time video, which delivers the immediacy required for safety and efficiency, reducing response times, improving coordination, and strengthening resilience at scale.
8- Financial Services
Similar to an educational service, traders and analysts rely on real-time video to share and stay ahead of shifting prices, breaking news, and high-stakes decisions where even slight delays mean lost opportunities or added risk.
- Who it’s for: Traders, brokers, financial analysts, and investors who require the fastest and most reliable access to live market communication channels.

10- Safety at Entertainment Venues
For entertainment venues and attractions, operational safety depends on real-time visibility for applications like ride cams and incident monitoring.
- Who it’s for: Theme park operators, interactive entertainment providers, event security teams, and venue managers prioritizing safety.
