Introduction

AVerMedia has officially introduced the CamStream 4K (BU113G2), a compact and portable video capture device tailored for use with DSLR, mirrorless, and action cameras, as well as camcorders. Positioned as a strong rival to the widely-used Elgato Cam Link 4K, it delivers identical plug-and-play convenience while enhancing functionality with additional features. These include support for uncompressed RGB24 color at 1080p60, HDR input compatibility at 4K60, 1440p144, and even 1080p240, along with a built-in 1/4" cold shoe mount for easy attachment to camera setups. Priced at $120, it’s slightly more expensive than its competitors, reflecting AVerMedia’s focus not on affordability, but on delivering top-tier performance in this category.

The primary function of the CamStream 4K is clear: transforming your existing camera into a powerful tool for high-quality recording and live streaming. Using its HDMI 2.0 input, the device captures both video and audio signals from your camera and transmits them to compatible devices—be it Windows, macOS, Android, or iPadOS—via a 5 Gbps USB connection. This same USB connection powers the unit, eliminating the need for an external power source and streamlining setup. Once the signal reaches your device, you're free to use it however you choose—whether for professional livestreaming, video conferencing, content creation, or simple high-resolution recording. Essentially, your camera becomes a premium-grade webcam, ready for any application.
