The big difference-maker here is that DJI’s using digital transmission technology, not the analog tech that a lot of other FPV cameras and goggles rely on. This means pilots can stream 720p footage (at either 120 or 60 frames per second) from a drone to the goggles with a latency of 28 milliseconds from up to 2.5 miles away.
The air unit can simultaneously record the live feed as 1080p / 60 fps or 720p / 120 fps footage onto a microSD card. The goggles can also record the live feed to a microSD card (though only at 720p / 60 fps). In the event of a crash, the on-goggle recording allows for quick playback that can help a pilot determine where their drone went down and ensure they walk away with some footage in the event of a loss of the microSD card on the drone.
The faster frame rates and the increase in resolution mean pilots will be able to see obstacles that can get obscured by standard-definition FPV footage, like power lines or tree branches. Higher-definition footage and faster frame rates could also make drone racing more compelling to watch since pilots and viewers will be able to better make out competitors passing in front of (or being chased by) the live feed coming off a drone. (That said, drone racing leagues would have to adopt DJI’s tech as a standard for any of this to matter.)
The returns of those improvements were made clear during a short demo that DJI offered the press on Tuesday. I was able to make out the details of nearby trees as well as another nearby drone when using the new FPV goggles in “audience mode” (with a more capable pilot at the sticks). The live footage was crisp and clear, and I didn’t notice any stutters or loss of signal, though the drone never flew more than a few hundred feet away.
DJI also strapped the air unit and FPV camera to a few remote-controlled trucks, and as I drove one around the grass, I saw a bumblebee fly in front of the camera — a detail I probably would have missed with a standard-definition transmission at a lower frame rate.
DJI FPV Air Unit
FPV through the DJI Digital HD Air Unit is the way FPV is meant to be. This 5.8Ghz air unit (FPV camera + VTX) provides amazing visual clarity that is able to be transmitted to your DJI Goggles through its built-in receiver module. The DJI FPV Air Unit provides ultra-low latency HD digital image transmission, built-in 1080p/60fps DVR recording, and eight frequency channels to allow up to eight pilots to fly simultaneously.
Digital HD systems have traditionally been rather bulky and unwieldy to mount on a mini quad. Not anymore. With this air unit, you can comfortably fit the module in your mini quad stack (probably not slammed frames). The 'mini' camera fits easily into your existing builds, no weird mounting adapters.
DJI FPV Remote Controller
DJI's FPV Remote Controller was made for racing and freestyle pilots. The added switches give more configuration options than previous DJI remote controllers. Syncs perfectly with the DJI FPV Air Unit for seamless integration into your drone builds.
With the DJI FPV Remote Controller, parameters of each component can be adjusted remotely. Purchasing the DJI FPV Goggles and the DJI FPV Air Unit eliminates the need of any additional receiver. Users can also enjoy 7ms ultra-low latency between the remote controller and the air unit.
