Tri-band wireless for real production distances

Out in the field, the system’s 2.4, 5 and 6 GHz tri-band approach offers a noticeably steadier link than earlier CineView units, especially when working around other wireless systems. The RTMS 4.0 protocol constantly shifts data across the three bands to keep the picture locked, which enables a 1.6-mile line-of-sight range and keeps latency down to around 35 ms in 4K. It reacts quickly when you power up, which helps when you’re moving between setups.

4K60 in, out and through

Both transmitter and receiver are built to carry a full 4K60 workflow. On the transmitter, you will find SDI and HDMI inputs, plus a 4K loop-out, making it straightforward to run a director’s monitor and a wireless link from the same camera feed. The receiver mirrors its output via SDI and HDMI for production monitors or switchers. The system’s 8K-capable processor is doing the heavy lifting here, keeping encode and decode responsive while juggling multiple connections.

Wired iOS monitoring

The USB-C port on the transmitter provides a clean video feed to an iPad or iPhone and powers the device while it works. In practice, the wired feed feels very immediate, with latency low enough to focus on. It also opens up camera-to-cloud via the SEE app, letting you push takes to Frame.io from the device without waiting for the main media to offload.

Improved app control and monitoring

Accsoon’s updated SEE app adds a cleaner interface for LUTs, waveforms, false colour and recording. It’s practical when you want a fast, accurate preview without carrying another monitor. You can stream or record with a LUT applied, and the app’s vertical recording support is helpful when covering mixed-format briefs. Having four wireless receivers plus the cabled iOS device connected at once gives a crew plenty of monitoring options.

Heat management and powering

The new chassis runs cooler thanks to the adjustable fan settings. Outdoors, you can leave the fan in standard mode for consistent cooling, but when working near audio, you can throttle it back or switch it off entirely for short takes. Both units accept L-series batteries or DC input, and the option to bolt on a V-mount adapter keeps them aligned with larger rigs.

FAQs

How many devices can the CineView Master 4K feed at once?

A single transmitter can send to up to four wireless receivers or mobile devices simultaneously. You can also attach an iPad or iPhone to the transmitter via USB-C as a fifth monitoring point. Each receiver can be set to output 4K or HD, depending on the monitor you’re using.

Does the system handle mixed wired and wireless outputs at different resolutions?

Yes. You can run 4K60 into the transmitter and choose whether each receiver outputs 4K or HD. The wired USB-C feed to iOS can also be set independently, which helps when mixing 4K displays with older HD monitors on the same job.

How usable is the system in congested wireless environments?

The tri-band design gives it room to manoeuvre when the 5 GHz band is crowded. The 6 GHz channels, in particular, tend to stay cleaner on busy sets, and the system shifts between all three bands automatically to keep the link steady.

Can I use the CineView Master 4K for direct live streaming?

Yes. When paired with the SEE app on an iPad or iPhone, you can stream directly from the wired feed. The app supports LUTs, vertical formats and Frame.io uploads, which shortens the path from capture to delivery.

What power options are available for longer shoots?

Both transmitter and receiver accept L-series batteries or DC barrel input. For extended days, you can mount a V-lock battery using the optional adapter, which keeps the system running alongside the rest of a cine rig.
