There is no single best thermal drone. There are three DJI setups built for different jobs. The Matrice 4T is the one a crew carries to the job. The Matrice 5TD lives in a Dock 4 and flies on a schedule or an alarm. The Zenmuse H30T is a payload for a heavy lift aircraft you may already own. Pick by how the aircraft gets to the job first, then by the detail you need.
The three side by side
| Matrice 4T | Matrice 5TD | Zenmuse H30T | |
|---|---|---|---|
| How it flies | Carried by a crew | From a Dock 4, remotely | On a Matrice 400, 350 RTK or 300 RTK |
| Thermal sensor | 640 x 512, 1280 x 1024 with Super Resolution | 1280 x 1024, 2560 x 2048 in UHR mode | 1280 x 1024, with UHR mode |
| Temperature range | -20 to 150 °C and 0 to 550 °C | -40 to 150 °C and 0 to 550 °C | -20 to 150 °C and 0 to 600 °C (to 1,600 °C with filter) |
| Thermal zoom (digital) | 28x | 32x | 32x |
| Laser rangefinder | 1,800 m | 3,000 m | 3,000 m |
| Flight time | 49 minutes | 59 minutes | Set by the aircraft |
| Weather rating | Not listed by DJI | IP55 | IP54 payload |
All figures are DJI's, from the Matrice 4, Dock 4 and H30 spec pages.
Matrice 4T: the one you carry
The 4T suits crews who drive to the job: roof and solar inspections, powerline patrols, search and rescue, fire scene overwatch. It is compact, and its thermal images are radiometric (R-JPEG), so every pixel holds a temperature you can measure later. A near infrared light helps the visible camera pick out people at night. The SAR field bundle packs it for that work.
If you are torn between the 4T and the camera only 4E, our Matrice 4E vs 4T post covers that choice.
Matrice 5TD: the one that lives on site
The 5TD is for sites that want a thermal drone in the air many times a day without a pilot driving out: security perimeters, substations, mine sites, large solar farms. It shares the H30T's 1280 x 1024 thermal sensor, adds a 2560 x 2048 UHR mode, flies up to 59 minutes, and Dock 4 swaps its battery between flights. DJI has released only the dock version so far.
Our Dock 4 on shift post covers how that plays out through a night. If you already run a Dock 3 with a Matrice 4TD, our 5TD vs 4TD comparison covers what changed.
Zenmuse H30T: for the aircraft you already own
If your fleet already flies a Matrice 400, 350 RTK or 300 RTK (with RC Plus), the H30T adds high resolution thermal, a long zoom and a 3,000 m rangefinder without a new aircraft. Its thermal range reaches 1,600 °C with the filter, which suits industrial plant, flare stacks and firefighting. You give up the small size of the 4T, and it does not dock.
Solar inspection: what resolution do you need?
Enough to see a single cell clearly. Higher thermal resolution lets you fly higher and cover more panels per flight. In a DJI Dock trial on a Texas solar farm, the analytics provider asked for about 5.5 cm per pixel thermal from 40 m. Fly when sunlight is strong and steady, usually late morning to early afternoon, avoid passing cloud, and keep a radiometric record for warranty claims.
Night flying in Australia
For finding people and animals, thermal contrast is often best at night. Drones in the excluded category fly by day only. To fly at night you need a ReOC and licensed pilots, plus night training and testing, a risk assessment and documented procedures (CASA's templates under Instrument 01/17, or your own with an approval), as set out on CASA's night flying page. That is general guidance, not approval for your operation. We plan it with you alongside the purchase.
FAQ
What is the best thermal drone for search and rescue?
For crews who carry the aircraft, the Matrice 4T: compact, radiometric thermal, with a near infrared light for the visible camera at night.
Is the DJI Matrice 4T radiometric?
Yes. It saves R-JPEG thermal images, so you can measure temperatures afterwards.
Which thermal drone works with a dock?
Of DJI's current docks: the Matrice 5TD with Dock 4, and the Matrice 4TD with Dock 3.
What thermal resolution do I need for solar panels?
Enough to resolve single cells. In a DJI Dock solar trial, the analytics provider asked for about 5.5 cm per pixel thermal from 40 m.
Can I fly a thermal drone at night in Australia?
Yes, under a ReOC with licensed pilots, night training and documented procedures. Drones in the excluded category fly by day only.
