Hollyland Cosmo C2 – Wireless HDMI Video System, 1 Transmitter and 1 Receiver

Hollyland Cosmo C2 Wireless Video Transmission Kit 1TX + 1RX

Cosmo C2 is a wireless video transmission system based on Hollyland's HEVO 2.0 technology, with a line-of-sight range of up to 1,000 m and a latency of 33 ms that stays the same over long distances. One receiver can work with two transmitters, reducing the number of devices and cables, limiting wireless interference and keeping the two video feeds synchronised. Seamless frequency hopping automatically moves to a clean channel when interference is detected.

The transmitter has HDMI and 3G-SDI inputs with SDI loop out; the receiver has two HDMI and two 3G-SDI outputs, an RJ45 port for NDI HX3 and USB-C for UVC streaming directly to a computer without a capture card, plus RTMP streaming. Fractional frame rates are supported, FPS Booster can convert 24/25/30p inputs to 60p, and the last frame is frozen if transmission is interrupted. The transmitter runs on DC or NP-F batteries, the receiver on DC or V-Mount batteries.

This kit includes one transmitter and one receiver; a second Cosmo C2 transmitter can be added to the receiver.
