On February 27, DJI launched the DJI Dock 3, its first unattended platform deployable on vehicles, equipped with Matrice 4D/Matrice 4TD high-performance drones, empowering 24/7 unattended operations across all scenarios.
Less than a year later, DJI is once again positioning itself in the To B/G market. (Portal: Observation | After New Regulations Lock Down "Illegal Flights", DJI Pivots to Aggressively Target the To B/G Market with Clear Intentions)
On October 14, DJI released the fourth-generation unattended platform, DJI Dock 4, with comprehensively upgraded specifications: 25-second automatic battery swap, and 45 seconds from landing to takeoff again. The paired Matrice 5TD drone has a flight time of 59 minutes, operating temperature range from -40℃ to 50℃, and onboard AI capable of real-time recognition of 17 types of targets. The official domestic price for the combo is CNY 167,999.
However, what is truly worth pondering is not these numbers, but whose market DJI Dock 4 is actually seizing, and what grand strategy it is truly plotting.
01 What Exactly Does This 25 Seconds Solve?
For the first three generations of docks, the drones return to the cabin and lie down to charge, taking nearly half an hour for a single recharge. Half an hour is just a number on a spec sheet, but on-site, it represents a vacuum period.
Anyone who has done forest fire prevention watch duty knows this. The moment the previous drone lands and starts charging, if a suspected smoke point rises nearby, the one lying in the cabin cannot be launched. By the time it is fully charged, the fire situation has long changed.
This half-hour wait firmly nails the drone dock into the "scheduled check-in" mode: fly a round at 2 AM, fly a round at 8 AM, strictly by the book. Dock 4 twists this into something else: ready to go at any time.
The budget categories corresponding to these two concepts are completely different. The former counts as inspection equipment procurement, while the latter counts as emergency response system construction. The budget for the latter is much larger and more stable than the former.
02 The First Piece of Cake Seized Is Actually Human Jobs
The positioning term for Dock 4 is DFR, with drones acting as First Responders. It sounds intimidating, but in plain language, it means: when an incident occurs, there is no need to wait for people to run over.
The past chain was: incident occurs, dispatch personnel, drive, arrive on-site, take a look, return and write a report. Now it is compressed into: click a button in the backend, the drone opens its cover and takes off by itself, rushing to the scene at a maximum speed of 21 meters per second.
But the truly critical part is not the first half, but the second. After the mission flight, the system automatically compares the captured footage with historical images and 3D models, generates an annotated report by itself, and creates work orders automatically.
Previously, the most labor-intensive and experience-dependent step was people sitting in front of screens watching footage frame by frame. Now, this job has been taken over by onboard AI combined with cloud-based large models. You just type a sentence or upload an image in FlightHub 2, and it searches and alerts on its own.
A two-person inspection team with one vehicle costs at least CNY 300,000 a year in labor and vehicle expenses. At the price of CNY 168,000, what it is truly competing against is not other drone nests, but the annual cost of this team.
DJI has made this move very quickly. It pulls the procurement decision out of the "equipment price comparison" box and puts it into the "labor substitution" box. Once the box is changed, the objects of price comparison change entirely.
03 The Second Piece Is the Fiscal Money for Low-Altitude Infrastructure
For the low-altitude economy to truly take off, infrastructure must be built first. The logic is the same as for NEVs (New Energy Vehicles): no matter how well the vehicles are built, they are useless without charging piles.
Third-party agencies estimate that the domestic intelligent drone nest market will reach a volume of CNY 6 to 7 billion in 2026, with the national year-on-year growth of newly added drone nests exceeding 50% in 2025. Shenzhen plans to have over 1,200 take-off and landing points by 2026, Hunan 6,600, and Zhejiang over 5,000. Hundreds of prefecture-level cities across the country are deploying points at the county level, with a single city often requiring hundreds of sets.
Who is buying? Urban investment companies, low-altitude industry groups, emergency response departments, power grids, and public security. Where does the money come from? Special low-altitude bonds, fiscal subsidies, and annual operation and maintenance service fees.
Dock 4's position in this market is very clear: it is the only node capable of 7x24-hour normalized watch duty. When a city wants to build a network, it is the first thing that comes to the minds of those designing the plan. And once the bidding technical specifications are written based on a specific product, the replicated orders for the following years are basically secured.
04 The Third and Most Hidden Piece: The Work of System Integrators
Hardly anyone talks about this point, but I think it is actually the most critical.
DJI simultaneously launched Cloud API 2, an enterprise-level development kit, for free. It also includes a simulator, allowing debugging before the hardware arrives. Privatization of 4G enhanced image transmission and 3D modeling are also opened for free. According to official DJI figures: the development cycle for typical projects is compressed from 180 days to 30 days.
Free, open, and low threshold. It sounds like charity.
But have you ever thought about who was making money during those 180 days before?
It was the system integrators and software developers who helped power grids connect docks to the grid systems, and helped urban management connect nests to smart platforms. They made a living by gnawing on communication protocols, hand-coding call logic, and doing custom integrations. Now, these tasks are packaged into ready-to-use components and given away for free.
DJI calls it "DJI builds the foundation, developers build the houses." Translated differently, it means: I've covered the foundation for free; you either build on my site or dig your own.
The vast majority of integrators can only come. Once they come, they are in—M5TD, O4 ground station, FlightHub 2, the whole set. To date, DJI Dock has connected with over a thousand third-party ecosystem software platforms.
Over a thousand; this number is much more important than 25 seconds.
05 So What Exactly Is It Trying to Do?
I think there are four things. Although each is further-reaching than the last, each is also more important than the last.
First, shifting from selling equipment to collecting rent. From the first generation in 2022 to the fourth generation now, the Dock series has been deployed in over 80 countries, accumulating 8 million flight sorties and over 2 million hours of unattended operation. What does 8 million sorties mean? This is long past just shipment volume; this is operational volume. On this foundation, maximizing the duty cycle of a single node means you don't need to deploy many nodes to double the service capacity. Base stations never make money by selling cabinets.
Second, turning one-off deals into annual recurring revenue. Charging for hardware and giving away software for free seems contradictory, but it is actually the oldest trick in the book. The commercial version of FlightHub 2 public cloud is CNY 8,799 per year, with privatization negotiated separately. Dock inspection, maintenance, spare parts, backup drones, and major event support are now all listed separately for on-demand purchase. The industry is already shifting from selling hardware to "hardware plus annual O&M plus data services," with the proportion of services increasing year by year. Bring people in first, then collect slowly.
Third, solidifying standards through scale. Dock 4 does not have FCC certification and cannot enter the US; this is an open card. But thinking differently, if you can't get in, just thicken the home market. Over a thousand ecosystem partners, data from 8 million sorties, interface continuity across four generations of products—when the vast majority of systems in a market run on the same set of protocols, the matter of standards no longer requires anyone to issue a certificate.
Fourth, switching to a "rice bowl" unaffected by market fluctuations. On May 1 this year, two mandatory national standards took effect, coupled with the newly revised Public Security Administration Punishments Law. The consumer market froze overnight, with dealer sales dropping by nearly half around the Spring Festival. To B and To G are different; behind them is the rigid budget for national low-altitude infrastructure, driven by fiscal policy, indifferent to consumer sentiment. Dock 4 is the heaviest brick on this path.
Final Thoughts
Battery swapping merely shifts the wait from drone charging to battery charging. The battery compartment holds a maximum of three batteries, and a single battery still takes 27 minutes to fully charge, with 260 watt-hours and 400 cycles. If working continuously at high intensity for several hours, battery turnover may still fall behind. Under high-frequency rotation, batteries are consumables, and this cost must be factored in.
One dock, one drone, with no parallel operations. No matter how robust a single node is, it does not mean the entire network has no blind spots. For truly uninterrupted operation, either deploy more points or rotate two drones.
The "General Technical Requirements for Unmanned Aerial Vehicle Automatic Nests" has been released, featuring 37 tests and a single ruler for the entire industry. This is a double-edged sword for DJI, and the blade might point inward: raising the threshold to clear out small workshops is a good thing, but a unified ruler also means issuing tickets to all compliant manufacturers. The slight advantage DJI accumulated through de facto standards will be diluted into "everyone can pass the line." Once it becomes a consensus that every drone nest is tested against the same set of standards, the battle returns to cost, service, and understanding of the industry. These three things cannot be won simply by having fast battery swaps.
There is also a dead knot that no one has untangled: N take-offs and N landings. Currently, docks basically operate on a round-trip basis; taking off from Point A means returning to Point A. The operational radius is halved by the return-to-home battery requirement—the further you can fly, the more battery you must reserve to fly back. The day we can truly achieve taking off anywhere, landing anywhere, and receiving off-site resupply midway, drone nests will truly form a network; otherwise, they are just a bunch of dots.
Dock 4 is a milestone on this path, not the destination.
Back to the 25 seconds at the beginning. It is not snatching those few orders from competitors. It is snatching the rice bowls of inspection teams and pilots, the budget for emergency response, the fiscal opening for low-altitude infrastructure, and the 180-day work of integrators.
What it wants to do is turn drones from tools into infrastructure, and transform itself from a machine seller into a rent collector.
