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

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

Cosmo C2 achieves a super-low latency of just 33ms 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

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

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

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.

Versatile Power Options

The Cosmo C2 transmitter supports DC (locking) and NP-F batteries while the receiver supports DC (locking) and V-Mount batteries, ensuring your production keeps going at all times.

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.
