Accsoon CineView Master 4K Lite Wireless Video Transmitter

The Accsoon CineView Master 4K Lite Wireless Video Transmitter sends professional camera video over dual-band 2.4 GHz and 5 GHz transmission. It supports up to DCI 4K60 and UHD 4K60 over HDMI, 1080p60 over 3G-SDI, H.265 encoding, USB-C wired monitoring, and up to 1200' wireless range.

This 4K wireless video transmitter is built for camera operators, directors, focus pullers, and compact production crews that need reliable on-set monitoring.
