DJI Ronin 4D uses the brand-new DJI O3 Pro Video Transmission technology. This gives it a transmission range of 20,000 feet, which would be impossible with older methods. It supports the 2.4 GHz and 5.8 GHz frequency bands, as well as the DFS frequency band and the AES 256-bit encryption algorithm. This means that it can send a 1080p/60fps FHD feed to multiple remote monitors at the same time, with much better security, stability, and interference resistance. The DJI High-Bright Remote Monitor must be used with the DJI Ronin 4D Video Transmitter.
