Accsoon has introduced CineView Master 4K II, a wireless video transmitter-and-receiver system for production monitoring, recording and live workflows. The platform combines 2.4, 5 and 6 GHz operation with the company's RTMS 4.0 protocol and H.264 or H.265 encoding. HDMI supports DCI 4K and UHD up to 60p, while the 3G-SDI path is limited to HD formats.
The company specifies transmitter-to-receiver latency below 25 ms at 1080p60 and below 35 ms at 4K60, excluding camera delay. Its advertised range is at least 2.5 kilometres, measured at 1080p60 in an unobstructed, interference-free FCC environment. The system can feed up to ten monitoring devices, and both transmitter and receiver provide USB video output for wired phone or tablet monitoring.
Camera control runs from Accsoon's SEE mobile application when the device is connected to the transmitter over Wi-Fi. At launch, the published compatibility list covers selected Sony and Canon mirrorless cameras, with record, exposure and touch-focus controls depending on the model. Accsoon also lists Frame.io Camera to Cloud integration, putting wireless viewing, remote camera operation and cloud transfer into one compact field system.
The headline range and latency remain manufacturer measurements, not independent crowded-spectrum results. Accsoon does not publish sustained bitrate, packet-loss tolerance, recovery time, encryption details or performance when all three bands are contested. Camera control is unavailable through the receiver's USB connection, and the compatibility list is still limited. Pricing and shipping availability are also absent from the official product page, so production readiness will depend on regional certification, firmware and field testing.
