The Hollyland COSMO C2 HDMI/SDI Wireless Video 2-Transmitter System (2TX + 1RX) is a professional, broadcast-grade multi-camera wireless system designed for live video production, directors' monitoring, and cinema sets.

While traditional high-end wireless kits require a separate receiver box for every single camera on set, the COSMO C2 utilizes an advanced 2TX-to-1RX architecture. Powered by Hollyland’s updated HEVO 2.0 transmission technology, this production kit allows a single master receiver to simultaneously capture and display dual-channel video from two independent camera transmitters—saving valuable space on your monitoring rig or production desk.

 

Key Dual-Camera Performance Features

  • Simultaneous Dual-Stream Monitoring: The system handles side-by-side or split-screen rendering on a single monitor setup. The master receiver processes both uncompressed transmitter signals at once, outputting them seamlessly to switcher desks or dual displays via its dual HDMI and SDI output banks.

  • Massive 3,000-Foot Line-of-Sight Footprint: Utilizing an optimized HEVO 2.0 hardware layer, the system punches through heavy environments up to a maximum wireless radius of 3,000 feet (1,000 meters) under clear line-of-sight conditions.

  • Near-Instantaneous 33ms Latency: Video delays are kept down to a mere 33 milliseconds. This ensures that focus pullers, gimbal operators, and live directors can make precision, split-second technical choices without lag.

  • HEVO 2.0 Adaptive Frequency Hopping: Operating on the 5.1 GHz to 5.85 GHz spectrum, the units actively scan for signal clutter. If heavy local Wi-Fi congestion or venue radio interference is detected, the hardware seamlessly changes channels without dropping frames or interrupting your live monitoring feed.

  • Dual-Interface (HDMI + 3G-SDI) Versatility: Each transmitter accommodates both HDMI and pro-grade 3G-SDI inputs alongside a dedicated SDI Loopout port for local on-camera operators. The master receiver mirrors this with dual HDMI and dual 3G-SDI outputs to cleanly feed multi-viewer production monitors or live production switchers.

LOVE this Charger!
Style: Qi2 Charging Mount
This is one of the best chargers I have ever had! My phone stopped charging via the cord and this was my solution and what a awesome one it is! It charges very fast! I also LOVE the way it looks attached to my Tesla screen. Its like having a second screen. I can do Waze on one screen and Tesla navigation on the main screen. I can also control Sirius XM without having to subscribe to it separately for my tesla - which by the way is ridiculous if you already have a subscription…just make sure you done have Allstate DriveWise or other haptics that track weather you’re using your iphone while driving.

Nice Phone mount
Great phone mount—stable, easy to use, and gets the job done! I’ve been using this phone mount for a few weeks now, and it’s exceeded my expectations. It holds my phone securely, even on bumpy roads, and the adjustable arm makes it super easy to get the right angle. Installation was a breeze—took less than 2 minutes. The grip is strong without scratching the phone, and it feels sturdy overall. Highly recommend if you’re looking for a reliable mount!

Perfect Phone Mount: Secure, Versatile, and Easy to Install!
This phone mount has truly exceeded my expectations! It’s incredibly easy to install and holds my phone securely in place, providing total peace of mind while driving. What really sets this mount apart is its impressive versatility—I've never seen anything quite like it. The base attaches firmly to the air vent, and the adjustable arm allows me to position my phone precisely where I want it, with the freedom to tilt it up, down, left, or right. Plus, it doesn’t interfere with air flow from the AC, which is a huge bonus. Although my wife's phone case isn't MagSafe-compatible, the included metal ring works seamlessly with it, and my MagSafe case connects just as smoothly. I couldn’t recommend this product more—it’s been an absolute game-changer for us! This is a personal purchase, and I’m thrilled with it. I’ll be sure to update if anything changes.

Secure and great fit
I gave this product a chance and it did not disappoint! I did not need to read any instructions for installation and was able to quickly and easily figure it out. Installation takes less than 5 minutes. Just align the mount to the top corner of your tesla screen and turn the dial to adjust the tightness. Once tightness is set, just test to see if it’s really fitted by wiggling it around to check for looseness. I like the fact that I can adjust the angles of the mount easily. My phone can be angles to be on top or side of the Tesla screen. When driving, my phone does not shake one bit. When it’s time to remove my phone, just give it a quick pull to detach and that’s it. The build quality is also very nice and I like the design of it overall. I think it’s a well thought out product. Definitely would recommend to friends and family with Teslas.
