DJI, the worlds foremost manufacturer of commercial Drones, is now under the same scrutiny that Huawei is getting. ...
DJI maintains a detailed digital map of the entire USA, necessary because they pre-program all FAA specified restricted airspace and no-fly areas into all of their drones sold in the US. If they are also surreptitiously collecting all video streams of their products in flight, with the associated geoloc coding, they could well be building he most comprehensive low-altitude, high resolution, aerial imagery imaginable. Lateral views from just outside the no-fly regions, easily obtained with 120 degree lenses on most sports cameras, could build out quite a view of even highly sensitive locations.
I have seen no evidence that DJI drones send data back to their home base in China. However, I feel sure this is the major concern of security and intelligence specialists in questioning use of DJI technology by government activities. Further, certain emergency and security service drone operators likely need an override of the no-fly geoblocks in the DJI programming, meaning those official use devices would provide clear overhead views of sensitive areas.
Yeah, there is a lot of distrust of technology designed and built in China.
