Matrice 4D and Matrice 4TD share a Dock 3 airframe. The sensor is the buy.
4D is repeat visual: mapping, progress, change you can compare week to week. 4TD adds radiometric thermal: night, hotspots, electrical faults, a pad that launches because something is wrong now.
This is not a handheld post and not an M400 / L3 post.
4D: geometry on a cadence
High-resolution RGB, consistent geometry, dock scheduling. Construction progress, asset condition, visual change. The question is what changed on the site.
4TD: detection
Thermal plus visual. Low light. Utilities, fire, perimeter, emergency check flights. The question is where the problem is.
| 4D | 4TD | |
|---|---|---|
| Visual mapping / change | Primary | Secondary |
| Thermal | No | Primary |
| Night / low light | Weak | Why you bought it |
| Dock 3 | Native | Native |
Do not use 4TD as a survey camera. Do not use 4D as a night thermal program.
How we quote the pad
Inspection and monitoring with a visual file: 4D on Dock 3. Safety, night, electrical heat: 4TD. Some sites run both aircraft on rotation. FlightHub 2 does not blur the jobs.

FAQ
Can 4TD carry L3?
No. L3 is Matrice 400.
Do I need 4TD if I already own H30T on M400?
Different program. H30T is crewed inspection. 4TD is the docked thermal pad. Many fleets have both.
Will 4D see inside a building?
No. Dock aircraft do not replace a handheld walk.
