DJI Matrice 4TD English Translation
The DJI Matrice 4TD is a multi-spectral thermal imaging industrial drone optimized for DJI Dock 3. Its key strengths include a 54-minute flight time, IP55 rating, built-in RTK, omnidirectional obstacle avoidance and radar system. Equipped with four sensors (wide-angle, medium telephoto, telephoto and thermal imaging), a laser rangefinder and near-infrared fill light, it is designed for unattended autonomous inspection and all-weather operations.
