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.

Best make up removing wipes.
Size: 50 Count (Pack of 1)
These are the only makeup removing wipes I can use. They don’t burn my eyes and they remove the makeup very well. I do recommend staring them upside down so that the pads that are at the other end stay moist and are able to remove the make up without any issue. Highly recommend. Durable and don’t tear. Great product. Great price point. I have them on a subscribe and save.

Disappointed with these cleansing cloths!
Size: 50 Count (Pack of 1)
The cloths are nice and soft, however it’s very difficult to pull out just 1 sheet, I usually end up pulling several sheets and they cannot be put back in the container. This is just a waste of money and I will never buy them again!

I double cleanse. I find that mineral oil based makeup removers are hard to wash off. Oil based ones are nourishing and easier to remove but are all very dissimilar. I find formulations with active ingredient CAPRYLIC/CAPRIC GLYCERIDES high on the list are the best for my skin type. Combination/Oily(summer). RetinA/Retinoid , glycolic, Vitamin c user. These formulations emulsify everything. No scrubbing or excessive rubbing. No funny skin irritants or slimy film left on skin. MY Favorites: La Roche-Posay Micellar Cleansing Water for Sensitive Skin [all skins even those using actives]#1 My Favorite All year. Black Opal Even True Skin Perfecting Cream Cleanser [Good for dry skin or winter time]Discontinued Clarins Cleansing Milk with Gentian (Combination or Oily Skin)[A opaque 'milk' texture for Truly oily skin not drying but not hydrating]#2 Summers mostly. Pricey but worth it. Emulsifies everything and rinses well. CeraVe Foaming Facial Cleanser | Makeup Remover and Daily Face Wash for Oily Skin | Now Solutions Soothing rose facial cleansing oil[ Good for all skin types consistency is 'thin'ish'] #3 I like the texture its an oil but doesn't feel 'congested' greasy to me. Sheamoisture Even Radiant raw honey 3n1 cleansing balm[Room temperature butter texture for dry and or dehydrated skin. Possibly good for skin needing nourishment(shea and honey). IMO this is a 'wipe off cleanser. Say with a 'wonder cloth' or some such. Not a daily use but has its place for sure. May work as a hydrating face mask. Think Estee Lauder Triple cream(discontinued). Nice size and affordable. Cerave Makeup removing cleanser Balm[ A 'waxy' looking balm that seems whipped. All skin types]. Does what it says. IMO a wipe off cleanser even thought directions say rinse. I rinse then wipe then cleanse. Sometimes i just go directly to cleansing. Note no CAPRYLIC/CAPRICTRICERIDE or its derivatives in the ingredient list. This one took time for me to remove but its not greasy. Has other solvents, emollients and emulsifiers. Definitely a gentle skin conditioner. A good product.
