DJI O4 Air Unit FHD FPV Digital Video Transmission: DJI O4 video transmission system
If you're into FPV, the DJI O4 Air Unit Series is basically your new best friend. It's packing the DJI O4 video transmission system, which means you're getting ultra-low latency and controls so responsive, they'll make your head spin. And with its dual-antenna setup? You can push the limits up to 15 kilometers—yeah, you read that right. Whether you're dodging trees or just showing off over open fields, this thing keeps you connected.
Now, let's talk visuals. The DJI O4 Air Unit doesn't just capture 4K/60fps; it's like having a mini Hollywood in your drone. Upgrade to the Pro version, and you're looking at 4K/120fps—because why not? And with H.265 encoding, even at 1080p/100fps, everything's so smooth, your flights will look like they're straight out of a video game.
Got a need for speed? Racing mode slashes video transmission latency down to a mere 15 milliseconds. Plus, it supports up to eight aircraft racing at once. So, gather your friends (or rivals), because it's go time.
Sun too bright? No problem. The DJI O4 Air Unit Pro Camera Module teams up with the DJI Avata 2 ND Filter Set to keep your footage looking sharp, no matter how harsh the light. Colors pop, exposures are balanced—it's like magic, but real.
And for the tinkerers out there, it plays nice with Canvas Mode and Betaflight OSD settings. Customize your display to your heart's content. Plus, its featherweight design means it'll snugly fit into drone frames 2 inches and smaller. Versatile? You bet.
