The DJI Zenmuse H30T is the flagship inspection payload UAV Imaging flies on the Matrice 400. A single gimbal carries five sensors — wide, zoom, radiometric thermal, laser rangefinder, and an NIR auxiliary light for night work — so one flight captures visible detail, heat signatures, ranged dimensions and low-light imagery without a payload swap or a second sortie.

How UAV Imaging uses it
- High-detail standoff inspection — 34x optical zoom resolves cracks, corrosion, insulator and conductor damage on energized or fragile assets from a safe distance
- Every-module solar thermal scan — the 1280x1024 radiometric sensor covers four times the ground per pass of the previous generation, so a full array scans faster and hotspots read sharper
- Flare and vent stack inspection — zoom plus high-res thermal finds refractory damage, hot-spot leaks and corrosion from outside the heat envelope
- Transmission and distribution line patrol — zoom resolves splice, connector and insulator defects at line distance; thermal flags loose-connection hotspots before they fail
- Night and low-light operations — the NIR auxiliary light enables security overwatch, emergency response and dusk-to-dawn inspection windows the H20T could not fly
- Ranged defect documentation — the 3000 m laser rangefinder geo-locates and dimensions defects without contact, out to distances the H20T could not reach
- Search and emergency response — wide for situational awareness, thermal for body heat, NIR for darkness, zoom for confirmation, all on one aircraft
What the H30T adds over the H20T
The H20T remains a capable four-sensor payload. The H30T advances three things that matter on paying inspection work: thermal resolution jumps to 1280x1024 (four times the pixels, so larger arrays and structures scan in fewer passes with sharper anomaly detail); the laser rangefinder more than doubles its reach to 3000 m; and the added NIR light opens night and low-light windows the H20T could not fly. Paired with the Matrice 400's longer endurance, more of a site closes in a single mission.
Practical accuracy notes
- Radiometric thermal sensitivity of ≤50 mK resolves smaller temperature deltas than the previous generation, which sharpens early-stage hotspot detection on solar and electrical assets.
- Laser rangefinder accuracy is specified at ±1.0 m beyond 500 m; for high-rigour structural dimensioning at close range, the sensor is referenced against a known target before the deliverable.
- Hybrid zoom past the 34x optical point is a context and confirmation aid, not a substitute for a closer optical pass on truly small features.
How it pairs with the Matrice 400
The H30T is UAV Imaging's everyday inspection and thermal payload on the Matrice 400. For survey-grade mapping and stockpile volumetrics the airframe carries a dedicated LiDAR or mapping payload instead; for methane survey the Pergam Falcon laser sensor takes the mount; for confined-space and indoor work the entire aircraft changes to the Flyability Elios 2. The H30T owns the standard outdoor inspection, thermal and night envelope.
