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.

Cozy!
Color: Light Grey, Size: 30.0"L x 30.0"W x 7.0"Th
My bully breed loves her bed! It’s comfortable and soft which my dogs seems to love. It’s pretty durable as it’s held up pretty well in the washing machine. I wish it had a removable cover to make washing it easier.

Our dog loves it!
Color: Dark Grey, Size: 36.0"L x 36.0"W x 7.0"Th
We adopted a rescue dog from the police pound and had kept her outside for several years. Recently she has been asking to come inside. I bought her this dog bed hoping to establish a place for her to settle and feel safe when she is inside. She is a medium size dog, about 60 pounds, and this bed fits her perfectly. It is warm and comfortable. She liked it from the start and goes to it when in the house. The grey fur-look fabric is neutral and blends in unobtrusively. It has held up very well. I washed it one time but don’t think it had room to move well in the washer so it didn’t get as clean as I hoped. It could probably be washed better by hand in the bathtub. It dried well in the dryer.

Soft but flimsy

— Just wanted to add an update to say that after I left this review the seller reached out to me to get more feedback and ask how they could make the experience better. I didn’t respond because I was pretty busy. They followed up and informed me that they have issued a refund for my order and that I do not need to send the item back. I appreciate their customer service. — The product is extremely soft. The dogs seem to love it. However, the “donut” part doesn’t hold up at all and the whole bed feels really flimsy. Our dog was on it for a couple mins and when he got up there is an obvious dent from where he was laying. We got a similar bed from Costco a couple months ago for roughly the same price. The bed holds up its shape and feels solid/heavy. We wanted a second one but it was out of stock so we looked on Amazon and found this one. The dark gray one in the photo is from Costco and the light gray one is this product. I probably won’t send it back (too much hassle) but if your dogs are 25lbs+ this bed may not give the support you are looking for.
