Tri-Band Frequency Transmission
The CineView Master 4K boasts the RTMS 4.0 protocol, which integrates 2.4, 5, and 6 GHz frequencies. Intelligent dynamic adjustment of audio and video data goes across all three bands for faster connection times, lower latency, and easy management of multiple connections. With the new 6 GHz frequency, the CineView Master 4K unlocks 14 new channels and gigabit network speed.
Extended Long-Distance Transmission
Both receiver and transmitter units can communicate up to 1.6 miles away, thanks to their tri-band technology and hardware design.
Versatile Wired & Wireless Connections
The 3G-SDI and HDMI connections on the receiver can output video to a production monitor on set with stable, high-quality transmission for smooth on-site monitoring. Use the Accsoon SEE app to wirelessly monitor your system. The transmitter has a 3G-SDI input, HDMI input, and HDMI loop output port. A direct USB-C video output on the transmitter communicates directly with your iOS device. It can charge the connected device simultaneously and share your creations to Frame.io through Camera to Cloud integration.
New User Interface
An improved user interface makes for easy creative control over your stream, video settings, LUTs, WiFi, and other advanced settings using the SEE app.
8K Processor
A new high-performance A/V processor with 8K capabilities works in tandem with the RTMS 4.0 protocol for a 400% increase in processing capabilities over previous models. The system can easily create synchronized multi-video streams via tri-band technology.
Intelligent Heat Dissipation
Toggle between three different fan modes depending on the needs of your production. Standard mode allows for peak fan speeds for outdoor applications, quiet mode reduces the fan speed for studio setups, and off mode turns the fan off when you cannot risk the noise interfering with your production.
Multiple Power Options
Both units support power from both DC input and L-series batteries. There is also the option to add a separately available V-mount battery adapter.
Solid wireless system.
Useful for a director’s monitor setup and app is very solid for recording and seeing the image on set.
I also use it to grab frames to send to producers from the app. Makes that part easier than taking pics of a monitor
Seems to still add its own contrast curve in the app though but I still may need to fully learn the unit to get a proper image from the app.
Also i would not use the wireless for critical focusing, just not low enough latency.
Other caveat is that it is not small… def has some bulk to it… but it does a lot so Im fine with that.
Overall a 4 mostly due to latency and size. But def worth a buy when on discount.
Good for monitoring, but bad for recording

I bought a couple of them back in December, for conferences, we are recording directly to the Blackmagic Atem Extreme ISO and the cameras connected wireless are just pixels and tons of noise.
If you are just monitoring your image, they're great, fast and easy to use, but not for recording externally. :(

Does it auto hop channels during use if the channel it’s using becomes congested?
Asked by: Andrew
The Accsoon CineView Master 4K SDI/HDMI Wireless Video Transmission System automatically selects the optimal channel upon powering on to avoid congested or weak signals. However, once the device is in operation, it will not switch channels automatically. If you need to change the channel, you will need to do so manually.
