The Hollyland COSMO C2 HDMI/SDI Wireless Video Transmission System (1TX + 1RX) is a professional, broadcast-grade wireless monitoring kit tailored for cinematography teams, live television directors, focus pullers, and demanding production sets.
Building directly on the legacy of the Cosmo C1, the C2 system integrates Hollyland’s updated HEVO 2.0 processing engine. This base 1TX + 1RX package establishes a rock-solid single-camera pipeline while offering the unique scalability to expand into a multi-camera workflow (up to 2TX to 1RX) down the road without buying an extra receiver.
Key Technical Performance Features
-
Expanded 3,000-Foot Wireless Radius: Powered by the HEVO 2.0 hardware protocol, the system transmits uncompressed Full HD video across an expansive 3,000 feet (1,000 meters) line-of-sight range, easily covering large sports arenas, deep film sets, or complex multi-floor venue architecture.
-
Zero-Lag 33ms Monitoring Latency: Real-time data delay is kept to a near-imperceptible 33 milliseconds. Focus pullers can pull sharp focus on fast-moving subjects and directors can evaluate actor timing perfectly without a trailing delay.
-
Adaptive Frequency Hopping (AFH): Operating on the 5.1 GHz to 5.85 GHz spectrum, the COSMO C2 actively scans for radio frequency (RF) clutter. If it detects heavy local Wi-Fi traffic or venue interference, it seamlessly transitions to the cleanest available channel without dropping frames or freezing the video feed.
-
Dual-Interface (HDMI + 3G-SDI) Versatility:
-
Transmitter (TX): Equipped with 1× HDMI input, 1× 3G-SDI input, and a dedicated physical 3G-SDI Loopout port so local camera operators can plug an on-camera monitor straight into the transmission block.
-
Receiver (RX): Delivers dual signal distribution via 2× HDMI outputs and 2× 3G-SDI outputs to feed high-end production switchers, directors' cages, and client multi-view monitors simultaneously.
-
-
UAC Web Camera Mode: The receiver includes a plug-and-play USB-C output supporting USB Audio Class (UAC) and USB Video Class (UVC). This lets you feed the wireless video line directly into a computer as a webcam source for instant live streaming via OBS Studio, Zoom, or vMix without requiring an external capture card.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

I’m a little disappointed.
Format: Kindle
I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic.
I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop.
One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.

Vale is an 8 month pregnant omega working as a waitress at a strip club and a cam girl. She starts to get very creepy vibes from a regular at the club, and her baby daddy ghosted her. She has had an online relationship with a man named Bishop through her cam girl status. One night, bishop was paying to watch her sleep and ansthe creepy regular Andrew break in and watch her sleep he tells vale to come to him at his business now. She flees and finds herself at a large security company with some.hot of alphas who are there to help her. This imegaverse is a little different than I have read, but I am thoroughly enjoying it. Vale is not a traditional omega she was raised by a single beta mom, and the alphas are not normal alphas they have never really loved pack life. But they are ruthless mercenaries. They need her, and she needs them. I love the aspect of the stalker and now the plot twists at the end, so so good. Sometimes, it seemed a little slow and stale mated, but since this a duet, I think It was just her starting to have Vale get to know her alpha suitors. Cliffhanger for sure with this one.

That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me.
I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol

oh wow
Format: Kindle
I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!
