DJI is set to release its new O4 Air Unit, a highly anticipated upgrade to its drone video transmission system. This advanced unit, currently in beta testing, promises improved low-light performance, faster exposure adjustments, and enhanced signal penetration, potentially revolutionizing both consumer and custom FPV drone experiences.
Technical Specifications Overview
The upcoming O4 Air Unit boasts impressive technical specifications, featuring a 1/1.3" sensor camera with an F2.0 aperture, matching the capabilities of the DJI Avata 2 and Osmo Action 4.
Its design incorporates a dual antenna setup for improved signal stability and a built-in heat sink for efficient thermal management. Versatility is enhanced through multiple mounting options, including 20×20 and 25.5×25.5mm configurations, catering to various drone builds.
These specifications position the O4 Air Unit as a significant advancement in FPV technology, promising enhanced performance and flexibility for drone enthusiasts and professionals alike.
O4 Air Unit Variants
Two distinct versions of the O4 Air Unit are in development: the Pro and Lite models. The Pro variant is expected to incorporate the same advanced system found in the Avata 2, offering superior performance and features
. In contrast, the Lite version is speculated to utilize a smaller 1/2" sensor, potentially similar to the one used in the DJI Neo drone.
This dual-model approach aims to cater to a wider range of users, from professional cinematographers to hobbyist FPV pilots, by providing options that balance performance and affordability.
Performance Enhancements
Significant improvements in video transmission quality and responsiveness characterize the O4 system. It offers superior low-light performance compared to its predecessor, the O3 Air Unit, and features near-instantaneous exposure adjustments when transitioning between bright and dark areas. The system’s enhanced signal penetration capabilities allow for maintaining stable video feeds even through buildings with minimal interference. These advancements address key challenges faced by FPV pilots, particularly in dynamic lighting conditions and complex urban environments, potentially elevating the overall drone flying experience.
Release and Integration Details
While an official release date for the DJI O4 Air Unit has not been confirmed, speculation suggests a potential launch in November/December 2024.
The O4 system is already integrated into the DJI Mini 4 Pro and Avata 2 drones, showcasing its capabilities in existing products. Unlike DJI’s complete drone systems, the standalone O4 Air Unit is not expected to include GPS or built-in restrictions, allowing for greater flexibility in custom builds. However, DJI’s ongoing issues with the US government may impact the release timeline and features. The company appears to be prioritizing the integration of the O4 system into their newer drone models, potentially as a strategy to boost sales of complete drone packages rather than offering the transmission system separately
