Accsoon CineView Master 4K Lite
Accsoon has announced the CineView Master 4K Lite, which features RTMS 4.0 Dual-Band wireless transmission. It is a wireless video transmission, monitoring, and live streaming system aimed at professional film and live production workflows. The system supports end-to-end DCI 4K60 transmission and is part of Accsoon’s CineView ecosystem.
Essentially, the CineView Master 4K Lite is a more affordable version of the CineView Master 4K, but with a more limited operating range (1200 ft / 350m, as opposed to 820ft / 2.5km), and slightly higher latency (<35ms as opposed to <25ms). It also only works on Dual-Band instead of Tri-Band. In saying that, it does offer a few new features that aren’t found in the CineView Master 4K.
The CineView Master 4K Lite features Accsoon’s proprietary RTMS 4.0 transmission protocol, and it uses a new-generation dual-band wireless technology operating on both 2.4 GHz and 5 GHz, with DFS support.

Having a dual-band system helps maintain signal stability in congested RF environments. The CineView Master 4K Lite also supports the H.265 codec, a higher efficiency codec providing better image quality at the same bandwidth.
Accsoon claims that the latency of the system is less than 35 ms and that it has a maximum transmission distance of up to 1200 ft / 350m. It also supports up to 10 groups of transmitters and receivers operating within close range.

One of the most interesting updates is the USB-C video output on both the transmitter and the receiver. This enables wired video output from either end of the system to mobile devices. Wired USB monitoring also allows the connected mobile device to be charged at the same time. The USB-C video output on both the transmitter and the receiver is an improvement over the CineView Master 4K, which only had the USB-C video out on the TX.
Another key update is expanded support for camera control. Users can now connect to supported cameras wirelessly. This is something you can’t do on the CineView Master 4K.
Supported controls include:
- Bi-directional remote record triggering
- Aperture control
- Shutter speed
- ISO
Camera control is available on select Sony and Canon cameras, including Sony FX3, FX30, FX6, A7C II, A7S III, A7 IV, and A9 III, as well as Canon R5, R6, R5 II, R6 II, R7, and R8. Accsoon states that support for additional camera models from Sony, Canon, and other manufacturers is planned.

CineView Master 4K Lite is designed to work within the Accsoon CineView ecosystem, so it will work with the CineView M7/M7H Pro units operating in TX or RX mode, as well as CineView Master 4K and CineView SE 4K transmitters and receivers.
The system supports monitoring on up to 5 devices simultaneously, including one wired and four wireless connections. Direct on-camera video output to mobile devices is supported. Both receiver and wireless monitoring via the Accsoon SEE App support up to 4K60 resolution.

Wireless monitoring can be done using the Accsoon SEE App, which features a vertically oriented user interface that has been optimized for mobile use. The app supports streaming and recording with LUTs applied, video rotation for vertical content, and calibration LUTs.
