Cosmo C2

Wireless Video Solution

Designed by experts with profound knowledge and market insight, Cosmo C2 features a powerful 2TX & 1RX design for enhanced wireless competence and boasts an ultra-long LOS range of 3,000ft (1,000m) and a super-low latency of just 33ms. Adopting the newly self-developed HEVO 2.0 technology, it supports seamless frequency hopping, thus ensuring a smooth and immersive experience. Combined with other powerful features and functions like NDI, UVC and RTMP streaming, this innovative kit will prove to be a great help for multi-camera livestreaming, broadcast, and more.

2TX & 1RX Solution

Cosmo C2 enables transmission between two transmitters and one receiver. This setup reduces the number of devices and cables needed, lessens wireless interference, and guarantees better synchronization of video feeds, all of which add to a more productive workflow.

More Range

3,000ft

Cosmo C2 boasts an ultra-long line-of-sight (LOS) transmission range of up to 1,000m (3,000ft), making it ideal for professional use in large venues, open areas, and complex buildings.

Less Latency

33ms

Cosmo C2 achieves a super-low latency of just 33ms[1] and the latency remains the same over extended distances, thus ensuring smooth and reliable transmission.

Hevo 2.0

Following a comprehensive upgrade, HEVO 2.0 technology redefines the experience. With extended transmission range, lower latency, and support for dual transmitters and one receiver, Cosmo C2 aims to elevate your workflow.

Seamless Frequency Hopping

Powered by self-developed HEVO 2.0 technology, Cosmo C2 automatically detects surrounding frequency interference and seamlessly switches to a clean channel, which ensures uninterrupted transmission and an immersive experience.

Live Streaming

UVC

Cosmo C2 supports UVC streaming[2] as well. With a USB-C to USB-C or USB-C to USB-A cable[3], you can directly connect the receiver to any computer without the need for capture cards, simplifying the real-time transmission of on-site video.

RTMP

Cosmo C2 enables RTMP streaming, a streaming method widely used for its low latency and compatibility with a wide range of live streaming platforms, such as YouTube and Twitch.

NDI Protocol Support

The receiver of Cosmo C2 supports Network Device Interface (NDI) protocol, allowing video streams to be transmitted over a single network cable. This eliminates the complexity and clutter of connections and creates a cleaner production space.

FPS Booster[4]

Through brand-new frame rate compensation algorithm, the RX can convert low frame rate inputs such as 24/25/30P to a high frame rate output at 60P, making the visuals smoother.

Fractional Frame Rate

Cosmo C2 can transmit HDMI/SDI fractional frame rate input and output, catering to your flexible needs while shooting.

Frozen Frame

When transmission is interrupted, Cosmo C2 freezes the last frame of the video feed, preventing the display of the manufacturer’s logo. You can also customize the logo image as you please with a USB flash drive.
