DJI Mavic 3 Thermal vs Autel EVO II Dual 640T V3
The DJI Mavic 3 Thermal (M3T) and Autel EVO II Dual 640T V3 are the most popular compact thermal drones for inspection, security and search and rescue. Both carry a 640 x 512 thermal camera. The M3T is lighter, flies longer at up to 45 minutes and adds a 56x hybrid zoom camera. The 640T V3 has a larger 0.8-inch 50MP visual sensor. Both weigh over 250 g, so in Pakistan they need PCAA registration within 15 days and a Remote Pilot Licence.

Quick answer
Choose the DJI Mavic 3 Thermal if you want the lightest, longest-flying package with strong zoom for spotting details from a distance, and you already use DJI. Choose the Autel EVO II Dual 640T V3 if you prefer a non-DJI platform or value its larger visual camera sensor.
For most solar, building and survey teams in Pakistan, the M3T is the more practical choice.

Thermal performance
Both drones use 640 x 512 thermal sensors, which is the standard professional resolution. Both are radiometric, so they record temperature data per pixel for later analysis and reports. In real inspections, image quality between them is close; lens choice, distance and technique matter more than the brand.
The M3T offers more digital thermal zoom and split-screen views with its zoom camera, which helps when checking a hot spot from a safe distance. DJI's thermal analysis software is widely used, which makes training and reporting easier. Our thermal drones for inspection guide (Thermal Drones for Inspection) explains the basics.
Visual camera and zoom
The M3T's two visual cameras give a wide view plus a 56x hybrid zoom, so you can read labels, spot cracked insulators or identify people without flying close. That is a big advantage for power line, tower and security work.
The 640T V3 uses a single larger 0.8-inch 50MP sensor, which gives cleaner wide images and better low-light visuals. It has digital zoom but no separate telephoto camera.
Flight time, size and deployment
The M3T is lighter, folds smaller and flies up to 45 minutes, against 38 minutes for the 640T V3. That means more panels or more kilometres of line per battery, and an easier carry in a backpack.
Both launch quickly. Teams already using DJI Enterprise drones benefit from shared batteries, apps and training on the M3T. Check flight times in real conditions with our drone flight time guide (Drone Flight Time Explained).
For solar farms, the extra minutes per battery add up across a large site: fewer landings mean faster surveys and less time in the heat for your team. For security work, longer time in the air means fewer gaps in coverage. In both cases, carry enough charged batteries and a way to charge them on site, as remote locations often have unreliable power. A small generator or vehicle charger can save a day of work.
Rules in Pakistan
Both drones weigh over 250 g, so under the Civil Unmanned Aircraft Rules 2024 they are Category II. Each must be registered with the PCAA within 15 days of purchase, and the pilot needs a Remote Pilot Licence (Remote Pilot Licence (Drone Licence) in Pakistan). Thermal work at night, beyond line of sight or over towns is outside standard conditions and needs permission.
Outdoor flights were suspended nationwide in February 2026 and provincial Section 144 orders have followed, with some districts granting written permission for specific work. Check the drone ban status (Drone Ban Status in Pakistan: Federal and Provincial Tracker) before any job.
Accessories and expansion
The Mavic 3 Thermal supports an RTK module for precise positioning and a loudspeaker for search and rescue or security announcements. It uses DJI's enterprise ecosystem, including DJI FlightHub 2 for fleet management. Batteries and chargers are shared with the Mavic 3 Enterprise.
The EVO II Dual 640T V3 uses Autel's enterprise accessories and the Autel Smart Controller. An RTK version of the 640T V3 is sold as a separate model. Plan spare batteries for either drone: thermal jobs such as solar farms often need several flights per site.
Training and reporting
Buying a thermal drone is only half the job. Your team needs training in thermal basics: emissivity, reflections, time of day and safe distances. Most inspection clients expect a report with marked thermal images and temperature readings. DJI's thermal analysis software and Autel's enterprise tools can both export radiometric images, and third-party inspection software works with both.
Start with simple, repeatable jobs and build a standard procedure before taking on large contracts.
Who should buy which
- Solar farm inspection: M3T, for flight time and portability.
- Power lines and towers: M3T, for the 56x zoom.
- Search and rescue: either; M3T for longer time on station.
- Organisations that prefer a non-DJI platform: 640T V3.
- Better low-light visual images: 640T V3.

Verdict
The DJI Mavic 3 Thermal is the better all-round thermal drone for most teams in Pakistan. It is lighter, flies longer and its zoom camera makes inspections faster and safer.
The Autel EVO II Dual 640T V3 is a capable alternative with a larger visual sensor, and a good fit for organisations that prefer Autel. Both are Category II: register with the PCAA, use a licensed pilot and check current ban status and permissions before flying.
