The DJI O4 Air Unit Series comes in two SKUs: DJI O4 Air Unit Pro boasts an enhanced imaging capability with a 1/1.3-inch image sensor, capable of recording 4K/120fps video. It also supports 10-bit D-Log M color mode and a 155° ultra-wide FOV, capturing the vast expanse of the world in unparalleled detail. DJI O4 Air Unit weighs just 8.2 grams and features a 1/2-inch image sensor capable of capturing 4K/60fps video, offering both portability and versatility.Operating Frequency: 5.170-5.250 GHz, 5.725-5.850 GHzPower output at the EU usage frequency (in mW):5.1 GHz: <23 dBm (CE) ≈ 199.53 mW 5.8 GHz: <14 dBm (CE) ≈ 25.12 mW Review: Great price, capabilities, small size and doesn’t weigh much - An amazing tiny bit of kit for your FPV drone, replaced a much heavier Caddx vista in two of my smaller cinewhoops which has improved them greatly (better handling, longer flight times), plus I have a backup recording on them on the unit which isn’t bad. Means I can also use my N3 goggles which I prefer wearing than my others. A reasonable price as well given what it can do. It is a bit unprotected and fragile though, especially the camera cables so need to be mindful of that. You can get 3rd party metal cases for air unit and camera which might be worth it on some kit. Review: HD video for whoops. Yay!! - Finally HD video on 1s whoops.
