What is the maximum video transmission distance of the DJI Mavic 4 Pro and what technology does it use: The DJI Mavic 4 Pro is equipped with O4 transmission technology, the fourth generation of DJI's proprietary transmission system, which allows for a maximum video transmission distance of up to 20 kilometers under optimal conditions. This technology utilizes dual links on the 2.4 GHz and 5.8 GHz bands, automatically selecting the most stable frequency to ensure a smooth connection between the drone and remote controller, even in environments with high interference.

This extended transmission capability represents a significant advancement for operators requiring real-time monitoring over long distances, such as infrastructure inspections or outdoor sporting event coverage. The ultra-low latency and high-definition video resolution maintained during flight allow for a seamless viewing experience on the controller or paired mobile device.

To illustrate, if the pilot operates in open rural areas or over agricultural fields, they can maintain a clear view of the surroundings up to 20 kilometers without experiencing interruptions, provided they maintain line of sight and ideal signal conditions. This advantage not only improves operational efficiency but also allows for more precise framing control and real-time decision-making, which is essential for high-end audiovisual productions.

Furthermore, O4 technology also improves signal penetration in urban environments, helping to reduce the impact of buildings, Wi-Fi signals, or other devices that could interfere with connectivity. Compared to previous models like the Mavic 3, this new system presents a notable improvement in signal stability, response time, and visual quality, positioning it as one of the most robust transmission systems on the market.
