DJI SDR image transmission is developed based on software-defined radio technology and adopts SDR and Wi-Fi dual-standard image transmission technology. SDR technology brings stable anti-interference, super strong penetration and other image transmission performance; if there is a temporary monitoring need, DJI SDR image transmission also supports image transmission via Wi-Fi, providing a more flexible monitoring method for the team.

◆ Features

Kilometer-level transmission, strong penetration guarantee
DJI SDR image transmission has a transmission distance of up to 3 kilometers, which can be competent for large-scale mobile shooting scenes. And it has super strong penetration, which can meet the needs of on-site image transmission monitoring in various complex environments.

20Mbps high bit rate, 1080p high-definition image quality
DJI SDR image transmission supports 1080p/60fps transmission specifications, with a transmission bit rate of up to 20Mbps, making monitoring and collaboration smoother.

Senseless automatic frequency hopping
DJI SDR image transmission supports senseless automatic frequency hopping between three frequency bands: 2.4 GHz/5.8 GHz/DFS*. If there is channel interference, it can automatically switch to the best channel, without fear of complex environment challenges.
* Some regions do not support the 5.8 GHz band or DFS band. Please refer to local laws and regulations for details.

No limit on the number of receivers
In broadcast mode, each image transmission transmitter can be connected to an unlimited number of receivers, providing a high-quality monitoring experience on multiple receivers to meet the independent monitoring needs of multiple types of work.

More practical functions
35 milliseconds low-latency transmission: With a latency as low as 35 milliseconds, monitoring is smoother and collaboration is more efficient.
Metadata transparent transmission, professional upgrade: DJI SDR image transmission supports SDI metadata transparent transmission of mainstream movie cameras such as ARRI and RED, making it convenient for directors, directors of photography and DIT teams to understand detailed shooting information in real time.
Voice call, efficient communication: DJI SDR image transmission supports long-distance voice transmission between the image transmission receiver and the transmitter, which can realize one-to-one real-time calls, making it convenient for photographers to communicate smoothly with directors or demand parties at any time.

Lightweight design, compact and easy to carry
The body adopts a lightweight design, and the antenna can also be folded for easy storage; a single image transmission transmitter or receiver weighs only about 145 grams, which is not only compact, but also supports a variety of installation methods to meet the needs of more scenarios.

Innovative USB-C interface, multiple monitoring methods
DJI SDR image transmission supports multiple monitoring methods, and supports simultaneous output of three SDR signals and two Wi-Fi signals. The image transmission receiver can output to the monitor via SDI/HDMI; the image transmission transmitter can be directly connected to a mobile phone or tablet via Wi-Fi to achieve low-cost monitoring of two-way signal transmission without a receiver.
On this basis, DJI SDR image transmission also adds a USB-C output monitoring method that combines stability and convenience. Users only need to connect the receiver to a mobile phone or tablet via a USB-C data cable to enjoy smooth and stable monitoring images.

Camera position switching
When the DJI SDR image transmission is connected to the DJI Ronin app via broadcast mode, users can flexibly switch between different camera positions in the app to meet the needs of monitoring different images.

Local recording and playback
The app supports local recording, and the recorded content can be viewed and played on the playback page.

Multiple monitoring options
Supports mainstream monitoring auxiliary tools such as LUT, peak, oscilloscope, false color, etc., providing a more professional monitoring experience.

◆ FAQ

How to maintain a drone?
Maintaining a drone requires regular inspection and care. First, make sure the battery stays charged and avoid overcharging or discharging. Clean the fuselage, propellers, and camera regularly to remove dust and debris. Check the propellers for cracks or damage and replace them in time. Calibrate the gyroscope and GPS before flight to ensure stability. After flight, check the battery, motor, and control system to confirm that there are no abnormalities. Update the firmware regularly to ensure the latest performance of the device. In addition, avoid flying in adverse weather conditions to extend the life of the drone.

What is the safe operation guide for Drone?
First, make sure you are familiar with local laws and regulations before flying, and avoid flying in no-fly zones. Maintain line of sight during flight to avoid loss of control or signal. Check the status of components such as batteries, motors, propellers, etc. to ensure that the equipment is in good condition. Avoid strong winds, heavy rain or thunderstorms during flight to ensure stable flight. Comply with flight altitude restrictions to avoid collisions with buildings or people. Calibrate GPS and gyroscopes regularly to ensure accurate navigation. Finally, shut down the drone in time and store it properly after the flight.

How to extend the life of drone batteries?
The key to extending the life of drone batteries is to avoid overcharging and over-discharging. Before each charge, make sure the battery is between 20%-80% and do not wait until the battery is completely exhausted. Use the original charger and avoid using non-compliant charging equipment. Avoid flying in extreme temperatures, especially in overheated or cold environments, as high temperatures will accelerate battery aging. Use the battery regularly and avoid leaving it for too long when not in use. Charge it promptly after the flight to avoid the battery being in a low power state for a long time.
