Thermal Resolution and Range Is the Real Difference
The H30T's 1280 x 1024 thermal sensor captures four times the pixel data of the M4T's 640 x 512 unit, a genuine difference for identifying a smaller heat signature at distance rather than just seeing a hotspot exists. Its temperature range also runs wider: 0°C to 600°C on low gain against the M4T's 0°C to 550°C, extending to 1600°C with the optional filter fitted, relevant for industrial plant or fire investigation work involving genuinely extreme temperatures. DJI doesn't publish a percentage or degree accuracy figure for the H30T the way it does for the M4T, giving a Noise Equivalent Temperature Difference (NETD) of ≤50mK@f/1.0 instead, a different kind of measurement and not directly comparable to the M4T's ±2°C/±2% figures.
Zoom Reach Isn't Close
The H30T's zoom camera reaches up to 400x digital zoom with a 34x hybrid zoom baseline, well beyond the M4T's 112x hybrid maximum. For inspection work where standing off at distance matters, powerline corridors, tall structures, wide search areas, that extra reach is one of the clearest practical differences between the two setups, not a marginal spec sheet gain.
Weight and Deployment
The M4T's 1,219g takeoff weight against the M350 RTK's up to 9.2kg (before the H30T's own 920g is added) is a substantial difference in how each system travels and deploys. The M4T suits a small team moving between sites in a day; the M350 RTK platform is built for fixed, planned deployments where the heavier airframe and vehicle-based transport aren't a constraint.
Choosing Between the M4T and Matrice 350 RTK + H30T
Thermal inspection, search and rescue or emergency response work where a complete, portable aircraft at a lower entry cost covers the job points toward the M4T. Work needing genuinely higher thermal resolution, extended temperature range for extreme-heat subjects, or zoom reach well beyond 112x, utility corridor inspection at distance, large-area search work, points toward the M350 RTK and H30T combination, budget and deployment logistics allowing for it.

Common Questions
Both. The 1280 x 1024 sensor captures more detail than the M4T's 640 x 512, and its temperature range extends further on both high and low gain, particularly with the optional filter fitted.
No, the H30T's official spec sheet gives a Noise Equivalent Temperature Difference (NETD) figure instead of a ±°C or ±% accuracy figure, a different measurement to the M4T's stated accuracy.
Both its listings on Drone Safe Store show as discontinued. The H30T payload itself is in stock, worth confirming M350 RTK availability directly before planning around this combination.
Between roughly £18,949.00 and £21,519.00 depending on the M350 RTK bundle, against the M4T's £5,910.00, three to four times the price.
The H30T, at up to 400x digital zoom against the M4T's 112x hybrid maximum.
