Hollyland Cosmo C2 HDMI/SDI Wireless Video 2-Transmitter System

The Cosmo C2 HDMI/SDI Wireless Video 2-Transmitter System from Hollyland allows you to wirelessly transmit high-resolution video up to 1080p60 over long distances up to 3000' using two transmitters to a single receiver, allowing flexible video monitoring and distribution for your studio or field production. This kit comprises two transmitters and a receiver that communicate over the 5.1 to 5.85 GHz wireless frequency range. Additional improvements to the series include HEVO 2.0 technology, UVC/RTMP/NDI|HX streaming support, and expanded power options.

Strong Signal Strength, Seamless Frequency Hopping

The Cosmo C2 can transmit 1080p60 video up to 3000' line-of-sight with a low 33 ms latency. The system operates on the 5 GHz frequency band, automatically detecting surrounding frequency interference and seamlessly switching to a clean channel via HEVO 2.0 technology. This makes for an uninterrupted transmission signal.

Connectivity

• The transmitters feature one HDMI input, one SDI input, and one SDI loop output.
• The receiver features two HDMI outputs, two SDI outputs, and an RJ45 Ethernet port.
• USB-C ports on all the units allow you to connect to the included USB-C OTG adapter and your personal computer for UVC streaming.

RTMP and NDI|HX Streaming

The Cosmo C2 unlocks RTMP streaming for direct live streaming to YouTube, Twitch, and other platforms. The receiver unit supports NDI|HX protocol, transmitting video streams via a single network cable for a cleaner production space.

FPS Booster, Fractional Frame Rate

Using a frame rate compensation algorithm, the Cosmo C2 receiver can convert low frame rate inputs like 1080p24/25/30 to high frame rate outputs at 1080p60, making smoother visuals. The Cosmo C2 can also transmit HDMI/SDI fractional frame rate input/output signals to ensure flexibility while filming.

Frozen Frame

If your transmission is interrupted, Cosmo C2 can freeze the last frame of your feed, effectively preventing the display of the manufacturer's logo. There is also the option to customize the logo image if you prefer to use a USB flash drive for a more professional appearance.

Versatile Power and Mounting Options

Each unit can be powered via DC input using the included power supply when working on set. In field applications or in studio spaces with limited outlets, both units offer battery plate options. The transmitters feature an L-series battery plate, and the receiver features a V-mount battery plate for higher-capacity power sources. Use the 1/4"-20 threads on the units or the cold shoe adapter to secure them to the mounting configurations of your choice.

Elvid Slim SDI Cable RG-179 (2')

Elvid's Slim SDI Cable RG-179, 2' in length, is designed to carry up to 12 Gb/s data rates to support uncompressed UHD 4K video signals. At the same time it's suitable as a solution for studio patching applications.

The cable features low-profile, locking BNC connectors that offer a trustworthy connection between a camera and video peripheral such as a monitor, external recorder, or switcher. Due to its slim diameter and durable FEP jacket, the cable is flexible enough to rout around gear without tangling or knotting for a clutter-free camera rig, patch bay, or machine rack. Molded strain relief secures the critical point between the cable and connector and assures a trouble-free signal transfer, even if there's a tug or strain on the cable.

Low-Profile BNC Connectors

The cable's low-profile BNC connectors and secure locking connections are preferred for professional and critical applications.

Slim and Lightweight

Ideal for use on camera rigs and equipment racks, the RG-179 cable will weave around gear, patchbays, and switchers for clutter-free connections.

Tangle Resistant

Even though the cable is flexible, it won't tangle or knot, and it will keep areas with multiple cables free of cable clutter.

Supports 12G Data Rates

This cable supports 12 Gb/s data rates, which makes it ideal for high resolution and color fidelity of UHD 4K signals.

Molded Strain Relief

Molded strain relief keeps this durable cable secure at the critical point where the cable meets the connector.
