Frequently asked questions
Which drones have a thermal-imaging function? DJI models such as the Mavic 2 Enterprise Advanced offer high-resolution thermal and RGB cameras with up to 32× digital zoom.
Are drones with cameras allowed? Yes, under certain conditions and with the required registration. They must not fly over residential properties without consent.
On fawn rescue: Thermal drones locate fawns in tall grass before mowing work and enable their safe recovery.
Reliability: Accuracy depends on sensor resolution, flight altitude and ambient conditions. When applied correctly, they deliver precise data.
