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.

Nice Filter Wrench for my Volvo V70XC!
Size: 86mm x 16
I was needing a filter wrench for my 2001 Volvo V70XC and couldn't find anything that fit from the local auto parts stores. Not knowing what to expect, I took a chance on this one since most of the reviews were 5 star and the price was exceptional. When I received it, I was quite pleased with the construction and finish. I have a brand new oil filter housing for my Volvo (since the one currently on my car is chewed up from the former owner using slip-jaw pliers or something on it) and the fit is perfect! I have worked as a mechanic my whole life (aircraft & automotive), and spent a couple of years as a technician at an automotive dealership and I can say that the tool looks like it is designed for heavy-duty use. The stamped steel housing is thicker than those found in local auto parts stores and the drive adapter has a thick arc welded bead along the inside of the tool. So, it appears to be made to hold up to some fairly heavy torque. Although the product description states that it is 1/2", the drive adapter is actually made for direct attachment to a 3/8" drive. Perhaps this error stems from the fact that they offer a much larger wrench (118-131mm) and this is a more accurate description of their other offerings. The 3/8" drive adapter works perfectly and a 21mm socket fits nicely on the external hex. Fits with SAE sizes are a mixed bag, though. I was able to attach a 13/16" 12-pt. box-end wrench, but not the opposing open-end. A similarly sized 13/16" 6-pt. socket was extremely tight, so I wouldn't recommend this size and would just go with the 21mm if you had to use the external hex. Otherwise, just use the 3/8" drive adapter for easiest use of this tool. The adapter also incorporates ball detents on all four sides of the internal 3/8" drive, so your ratchet or extension won't easily fall off while in use. Since this tool is made for oil filter removal & installation, I'm sure that it will deliver as promised. I'll post an update after my next oil change and I get a chance to use it and install the new filter housing I have.
