HOLLYLAND COSMO C1 PRO Professional Wireless SDI & HDMI Video Transmission System (6S Multicam Master Production Kit)

Achieve absolute signal dominance on high-stakes movie sets, live event broadcasts, and sports arenas with the Hollyland Cosmo C1 PRO. Engineered as the high-tier, professional evolution of the renowned Cosmo framework, this system integrates advanced HEVO wireless tracking technology alongside an enhanced high-gain hardware matrix. Operating on an accelerated $5.1\text{ to }5.8\text{ GHz}$ frequency spectrum, the Cosmo C1 PRO utilizes synchronous Adaptive Frequency Hopping (AFH) to eliminate the risk of black screens, signal drops, and RF interference. Delivering an uncompressed, razor-sharp 1080p60 cinematic pipeline over a robust 1,000-foot ($300\text{m}$) line-of-sight range with a near-zero latency of 0.04 seconds, it provides the ultimate wireless link designed specifically for elite 1st AC focus pullers, executive video villages, and complex multicam (6S type) broadcast workflows.

Technical Specifications

Hollyland Cosmo C1 PRO Pros and Cons

Pros

• Bulletproof HEVO Stability: Scans and jumps frequencies in 1 millisecond, preemptively cutting through severe wireless noise before it can freeze the client’s screen.

• Capture-Card-Free Webcasting: The receiver features an integrated hardware UVC engine, letting you pipe a clean 1080p60 feed directly into a laptop via USB-C for OBS Studio or Zoom.

• Precision Focus Pulling: An ultra-low 40ms tracking latency ensures focus pullers can safely track high-speed action and shallow depth-of-field lenses without lagging behind.

• No Signal Splitters Needed: Equipped with an SDI loop-out on the transmitter and dual SDI outputs on the receiver to easily feed local operator monitors and video villages simultaneously.

• Ruggedized Anti-Slide Lock: Built with a mechanical spring ball-catch plate that keeps heavy NP-F970 battery packs firmly anchored during intense, active run-and-gun camera tracking.

Cons

• HDMI Input Precedence: If both HDMI and SDI input cables are active on the transmitter at the same time, the module automatically defaults to prioritize the HDMI source.

• No Native 4K Transmission: Streamlined exclusively to deliver robust, uncompressed 1080p Full HD broadcast-tier streams; not compatible with native 4K monitoring pipelines.
