DJI Public Safety and Inspection Solution Comparison (Thermal)

Thermal sensors play a significant role in public safety/ law enforcement operations and inspection applications. Other uses for thermal imaging include, surveillance, search and rescue, and more. These situations rely on these sensors in order to spot points of interest that were not clear through traditional RGB imaging techniques.

1) DJI Matrice 300 RTK + Zenmuse H20N

The DJI M300 drone along with the public safety payload H20N, work in conjunction to create the ultimate air support system for advanced tactical operations. Exclusively designed for public safety operations, the H20N is a hybrid sensor that provides outstanding low light performance thanks to its starlight visual sensors. In addition, it supports synchronized zoom between its thermal and starlight night vision cameras. Users can scale both images at the same time, doubling efficiency and facilitating the comparison of details side by side.

2) DJI Matrice 300 RTK + Zenmuse H20T

When it comes to industrial Inspections, utilizing infrared solutions can drastically help organizations save not only millions in damages, but also the lives of their workers. These inspections help prevent injuries from fires, flash over, catastrophic failures, and related hazards. Undesirable temperature-related conditions can be detected early with these thermal solutions and proactively addressed before the situation escalates. Investing in a complete solution facilitates the data gathering process to assist in rapid decision-making when critical action is needed.  DJI has developed the M300 with H20T for experienced enterprise industrial inspection users; this solution provides the highest resolution visual zoom camera for inspection photos alongside thermal data.

3) DJI Matrice 30T

Many times professionals may require a more compact solution that can deliver high quality data, and for this reason the M30T is part of the industry-leading options for inspections in the same way as public safety missions, due to its powerful flight performance and high-resolution thermal capabilities.  The M30T has a multi-camera payload featuring: 640 x 512, 30Hz thermal camera, 1/2" CMOS 12 MP Wide camera, 1/2" CMOS 48 MP Zoom camera (200x max hybrid zoom), and laser range finder. The portability and multi-camera payload enables the M30T to be used in the most remote and hard-to-fly locations around the world.

4) DJI Mavic 3 Thermal

As a budget-friendly option, the Mavic 3 Thermal was designed for inspection applications requiring a lightweight and portable solution with advanced capabilities, which are specified in the table farther down in this article. The Mavic 3 Thermal offers an industry leading flight-time of 45 minutes and combines multiple cameras into a single payload including: 640 x 512, 30 Hz thermal camera, 48 MP wide camera, and an 12 MP zoom camera (56x hybrid zoom). Perfect for conservative budgets and users who desire portability over all else, the Mavic 3 is an advanced inspection or public safety unit that can be launched at a moments notice.

When comparing the above inspection infrared solutions, generally, the visual zoom of the H20T slightly outperforms the M30T, which then outperforms the M3T. 

(H20T > M30T > M3T).

The M300 + H20T and M30T feature:

  • Night scene (easier to see with visual camera at night in low-light scenarios)
  • IP rating (operations in rain and other adverse conditions)
  • Higher wind resistance (safely operate in higher winds)
  • Additional aircraft component redundancy
  • Built in FPV camera (additional view point when utilizing dual operators)
  • RC Plus compatibility (currently for M30 only, M300 support is planned)
  • Dual RTK modules (helps with electromagnetic interference)
  • Dedicated battery station for faster charging
  • Laser range finder (smart track, drop a pin, high-res grid, helps zoom camera to focus).
  • with the M30T and H20T when compared with the M3E.
  • Higher payload capacity for more powerful PSDK payloads (M300 >M30T>M3T).
  • Dual Remote Controller Option (1 to fly 1 to operate payload or handoff of drone)
For a more detailed comparison, we have outlined below the technical specifics published by DJI.
