Accsoon CineView SE 4K Wireless Video Transmission System

Overview

The Accsoon CineView SE 4K Wireless Video Transmission System is a professional wireless video kit consisting of a transmitter and a CineView SE 4K receiver. Designed for demanding productions, it delivers reliable end-to-end 4K30 video transmission with low latency, robust dual-band connectivity, and flexible monitoring options for crews of any size.

Using Accsoon’s patented Dual Band technology, the system combines 2.4 GHz and 5 GHz frequencies to maintain a stable connection even in complex RF environments. With a line-of-sight range of up to 400 m and latency as low as <50 ms at 1080p, it provides near real-time monitoring for directors, focus pullers, and clients.

The kit supports HDMI and SDI connectivity, USB video output, wired mobile monitoring, camera control functionality, and simultaneous transmission to multiple receivers and smart devices. Its compact aluminium construction, fanless design, and wide operating temperature range make it ideal for both studio and location work.

Core Features

• End-to-end UHD 4K30 transmission from input to output.
• H.265 compression for improved clarity and efficient bandwidth use.
• Up to 400 m transmission range with low-latency performance.
• 12 adjustable bitrate levels for optimised production workflows.
• Remote camera control including exposure and record triggering.
• Touch autofocus control via compatible monitoring devices.
• USB-C wired monitoring with near zero-latency output.
• Fanless aluminium design for silent operation.

True 4K Workflow & Image Processing

The CineView SE 4K delivers full end-to-end 4K30 image transmission, supporting encoding, wireless transmission, decoding, recording, livestreaming, and USB output to mobile devices. By utilising advanced H.265 video compression, the system provides improved image clarity and smoother transmission while maintaining efficient bandwidth usage.

With 12 levels of adjustable bitrate, users can fine-tune performance based on shooting conditions, distance, and production requirements, balancing image quality and signal stability as needed.

Camera Control & Smart Monitoring

A major addition to the CineView SE 4K system is integrated camera control. Users can remotely adjust key camera parameters such as ISO, aperture, shutter speed, and white balance directly from compatible monitoring devices.

The system also supports touch autofocus control, allowing focus adjustments by tapping or dragging on the monitoring screen. Bi-directional record triggering enables seamless start/stop control between the camera and connected monitoring devices, improving efficiency on set.

Supported camera models include: Sony FX3, FX30, A7C II, A7S III, A7 IV, A9 III, Canon R5, R6, R5 II, R6 II, R7, R8. Compatibility is expected to expand via future firmware updates. 

Operating Distance, Latency & Connectivity

The system operates at distances of up to 400 m (line of sight), with claimed latency below 50 ms at 1080p. This makes it suitable for dynamic shooting environments where real-time monitoring is essential.

Both transmitter and receiver units feature USB-C video output, enabling wired monitoring on mobile devices for close to zero-latency performance. This connection also supports simultaneous mobile device charging via USB-C or Lightning, making it practical for extended shooting sessions.

The transmitter supports HDMI and 3G-SDI inputs, while the receiver provides HDMI (up to 4K30) and 3G-SDI (up to 1080p60) outputs for compatibility with professional monitors and production gear.

Design & Power

Each unit measures approximately 11 x 3.27 x 7.4 cm (antennas excluded) and weighs 245 g (without antennas). The aerospace-grade aluminium housing ensures durability while maintaining a lightweight footprint.

The fanless cooling system enables ultra-quiet operation, ideal for interviews and sound-sensitive environments. Power options include NP-F550, NP-F750, and NP-F970 batteries or DC input (7.4 to 16.8 V), with average power consumption of just 4.4 W.

The system operates reliably in temperatures from -10 to 40°C, making it suitable for a wide range of production environments.
