DJI Dock 4 vs DJI Dock 3: Key specifications

DJI Matrice 5TD vs Matrice 4TD vs Matrice 4D: Key specifications

The aircraft is arguably the most important part of the buying decision.

Dock 4 pairs with the new Matrice 5TD, while Dock 3 currently only supports the Matrice 4TD and Matrice 4D.

Although all three are enterprise aircraft, they are designed around different imaging and operational priorities.

DJI Dock 4 vs DJI Dock 3: Battery swapping vs battery charging

The standout development in DJI Dock 4 is its automated battery-swapping system.

DJI Dock 3 charges the aircraft battery after landing. Under specified conditions, it takes approximately 27 minutes to charge from 15% to 95%.

DJI Dock 4 takes a different approach.

Instead of waiting for the aircraft's battery to recharge, the dock automatically exchanges it for a prepared battery.

The swap takes less than 25 seconds, enabling an operational turnaround of under 45 seconds.

Why does this matter?

For organisations flying occasional scheduled missions, the difference may have limited operational impact.

For teams requiring repeated or time-critical deployments, this is transformative: Think DFR, or security.

With Dock 3, the aircraft returns to charge between missions. With Dock 4, it can exchange its battery and prepare for another flight almost immediately, provided a charged battery is available.

The key takeaway: Dock 4 is particularly valuable when reducing downtime between flights matters more than simply completing a scheduled mission.

Although, an important caveat as that Dock 4's fast turnaround does not mean unlimited continuous flight. Available charged batteries, charging cycles, aircraft condition and operational requirements still affect overall system availability.

Dock 4 vs Dock 3: Flight performance and environmental protection

Dock 4 also brings improvements in aircraft endurance and environmental capability.

The Matrice 5TD delivers up to 59 minutes of flight time, compared with up to 54 minutes for the Matrice 4D and 4TD.

That represents an additional five minutes of maximum stated endurance.

For long inspection routes or missions involving distant assets, the extra flight time provides greater planning flexibility.

The dock itself also has a wider stated operating temperature range:

• Dock 4: -40°C to 50°C.

• Dock 3: -30°C to 50°C.

• Ingress protection: Both docks are IP56 rated.

• Operating radius: Both systems support a maximum operating radius of 10km.

Dock 4 therefore provides an advantage for deployments in particularly cold environments.

However, both platforms are designed for demanding outdoor conditions.

DJI Matrice 5TD vs Matrice 4TD vs Matrice 4D: Which drone is best?

Choosing between DJI Dock 4 and Dock 3 also means comparing their compatible aircraft.

Currently, Dock 4 pairs with the Matrice 5TD, while Dock 3 supports the Matrice 4TD and Matrice 4D.

There has been a rumour of backwards compatibility, ie Matrice 5TD being used in Dock 3. This may come in a future firmware update, but this is to be confirmed.

All three are designed for automated enterprise operations, sharing features such as multi-camera imaging, laser rangefinding, intelligent obstacle sensing, and IP55 weather protection.

However, there are important differences in camera performance, thermal imaging, flight endurance and surveying capabilities.

Camera systems: Higher resolution vs surveying performance

All three aircraft feature wide-angle, medium tele and tele cameras, providing flexibility for everything from general site monitoring to detailed infrastructure inspection.

The Matrice 5TD introduces three 50MP visible-light cameras, compared with the 48MP medium tele and tele cameras found on the Matrice 4D and 4TD.

It also delivers up to 176× hybrid zoom, compared with 112× on the previous-generation aircraft.

For detailed visual inspection or for public safety/security operations, the Matrice 5TD has the advantage, combining higher-resolution cameras with greater zoom capability.

However, the Matrice 4D offers a key distinction: its 20MP, 4/3-inch wide-angle camera features a mechanical shutter.

This is particularly valuable for photogrammetry, helping reduce image distortion during flight and supporting accurate mapping workflows.

The Matrice 4D also supports RAW photography, a minimum 0.5-second photo interval and dedicated mapping functionality.

DJI has made moves for the M5TD is offer survey capability though. While it has an rolling electronic shutter, algorithms work together to offer an accurate survey solution.

However, for surveying and mapping, the Matrice 4D remains a strong choice.

Thermal imaging: Matrice 5TD vs Matrice 4TD

Both the Matrice 5TD and Matrice 4TD incorporate thermal cameras, making them suitable for applications such as utilities inspection, search and rescue, security and industrial monitoring.

The Matrice 4D, by contrast, is designed primarily for visual inspection and surveying and does not feature a thermal camera.

The Matrice 5TD offers four times the native thermal pixel count of the Matrice 4TD, enabling more detailed thermal observation.

This is particularly beneficial when examining distant assets, monitoring temperature anomalies, or conducting search operations.

For thermal inspection, the Matrice 5TD represents a significant upgrade over the Matrice 4TD.

The Matrice 5TD and Matrice 4TD also support an NIR auxiliary light for enhanced low-light operations.

Laser rangefinding and obstacle sensing

All three aircraft incorporate laser rangefinding and obstacle-sensing technology, supporting safer flight and more informed inspection workflows.

The Matrice 5TD extends laser measurement range to 3,000m, compared with 1,800m on the Matrice 4D and 4TD.

It also integrates LiDAR and millimetre-wave radar into the aircraft's obstacle-sensing architecture.

AI recognition: More intelligent monitoring

The Matrice 5TD expands DJI's onboard AI recognition capabilities - increasing three target categories with the M4D Series, to 17 supported target types with the M5TD.

This expanded capability includes, selected animals, smoke, fire and river debris. It can also filter people and vehicles by colour.

Accessories: More options for operational response

The Matrice 5TD supports up to 450 g of compatible accessories, with a maximum takeoff weight of 3,050 g, offering support for carrying up to three accessories simultaneously.

In comparison, DJI Matrice 4D Series has a maximum payload capacity of 240 g, supporting a maximum takeoff weight of 2,090 g.

The Dock 4-M5TD launch brings with it the introduction of the DJI AL2 Spotlight, DJI AS2 Speaker, and DJI AP1 Parachute.

The M4D Series is compatible with the DJI AL1 Spotlight and AS2 Speaker - but the new speaker and spotlight with the M5TD bring enhancements.

For instance, the AL1 Spotlight offers 4.3±0.2 lux @ 100 metres, while the AL2 Spotlight trumps this, delivering 11 lux at 100 m.

Meanwhile, the DJI AS2 Speaker delviers up to 120 dB at 1 metre, compared to the previous generation's 114 dB at 1 metre.

The DJI AP1 Parachute provides an additional safety measure, with a minimum deployment height of 35m above ground level. It supports manual activation and specified automatic triggers.

The drones in the Matrice 4D Series are compatible with third-party parachutes. DJI has said that AP1 compatibility for the Matrice 4D Series will come early next year.

The DJI Matrice 5TD meets EU C5/C6 and UK5/UK6 compliance with the DJI AP1 Parachute installed, and thanks to its Independent Flight Termination System.
