1 Transmitter (TX) and 1 Receiver (RX) Solution

Cosmo C2 enables transmission between transmitter and 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

Cosmo C2 boasts an ultra-long line-of-sight (LOS) transmission range of up to 3,000 feet (1,000m), 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.

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.

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.

UVC 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.

RTMP Streaming

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.

FPS Booster

Through the brand-new frame rate compensation algorithm, the RX can convert low frame rate inputs such as 1080 P24, 25, and 30 to high frame rate output at 1080P60, making the visuals smoother.

Comprehensive Ports

The transmitter of Cosmo C2 possesses HDMI Input, SDI Input, and SDI Loopout. The receiver possesses HDMI Output A, SDI Output A, HDMI Output B, and SDI Output B.

Fractional Frame Rate

Cosmo C2 can transmit HDMI and 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.
