A 4K-recording camera and transmitter built around a low-light sensor, meant to replace a separate action camera on the drone.
Recorded specification
Every value carries the source it was read from. A property with no recorded source is marked as such rather than presented as a fact. If one of them is wrong, tell us: it is the fastest way it gets fixed.

| Onboard recordingThe best resolution the unit itself records, separate from what the goggles' DVR captures.

| Carries a cameraA complete drone is not in the camera category but carries one, and a digital air unit is a camera and a transmitter in one part.

This listing does not say which warehouse ships it. Most orders leave China, so expect import VAT and a carrier handling fee unless an EU warehouse is chosen at checkout.
Some links on this page earn us a commission at no extra cost to you, and that never affects any verdict on it. How this is funded.
