ActiveTrack uses deep learning, computer vision and advanced autonomous flight strategies to make complex, creative shots as simple as possible with just a tap. No GPS bracelets, no transmitters. The DJI Phantom 4 Professional has been trained to detect and recognize a number of common subjects including people, bike riders, vehicles and even animals.Once you have marked your subject, you can fly around them to create a huge variety of shots depending on the mode you are in. Choose from Trace, Profile or Spotlight, to give every scene you shoot that professional touch. As the Mavic is tracking, you can even select exactly where you want them in the frame, for more control over your final shot.
Here are the major features of the DJI Phantom 4 Professional Drone:
Small, foldable design. Obstacle avoidance system. Sharp, distortion-free stabilized 4K video camera. 12MP Raw and JPG stills. Records in portrait or landscape mode. Compact remote control. 23-minute flight time. Strong operating range. Orbit, follow, and other intelligent flight modes.
Every photo you take with the Mavic can be as big as 12 megapixels. Combined with an image sensor that has been expertly tuned for aerial images, all you need to do is find the perfect subject. You can even flip the camera 90° for portrait oriented shots, just like you do with your phone. If you are as concerned about editing as you are about composition, you can capture every photo in Adobe DNG RAW to give you all the editing power you need to turn any photo into a work of art.
With a sharp, stabilized, distortion-free 4K video camera, the $999 DJI Phantom 4 Professional is much more capable than you’d expect given its size. It’s an excellent choice for pilots looking for a more portable drone.
Rather than use Wi-Fi transmission, the Mavic uses DJI’s newly developed OcuSync transmission system. Part of the Lightbridge family, OcuSync performs far better than Wi-Fi transmission at all transmission speeds. OcuSync also uses more effective digital compression and channel transmission technologies, allowing it to transmit HD video reliably even in environments with strong radio interference. Compared to traditional analog transmission, OcuSync can transmit video at 720p and 1080p – equivalent to a 4-10 times better quality, without a color cast, static interference, flickering or other problems associated with analog transmission. Even when using the same amount of radio transmission power, OcuSync transmits further than analog at 4.1mi (7km)*.OcuSync goes even further than optimizing the communication mechanism and parameters of aerial imaging. There are several video transmission systems on the market claiming to offer video transmission with zero latency. However, it should be noted that the physical layer of those transmission systems is too simple to adapt to changes in the environment. When affected by signal interference, the image quality of the video being transmitted will fall sharply. This means these systems are not suitable for far field transmissions and transmissions in interference-heavy environments. Also, because these video transmission systems are not integrated into the whole system, latency will immediately start to rise up from 0 when working with devices including cameras and displays. OcuSync is able to strike a perfect balance between latency and receptivity, reducing latency to 5ms for remote controller transmission commands, 10ms for video data and 130ms for videos. More than low enough to ensure that Mavic is able to fly reliably despite interference. OcuSync’s integration with video processing, coding, and signal transmission systems also make it more cost effective. Before taking off, OcuSync will automatically scan the environment and choose the frequency band with the lowest interference, ensuring more stable video transmission. During a flight, it sends key flight parameters back for viewing in the DJI GO app and supports a maximum download speed of 40Mb/s for photos and videos.Before taking off, OcuSync will automatically scan the environment and choose the frequency band with the lowest interference, ensuring more stable video transmission. During a flight, it sends key flight parameters back for viewing in the DJI GO app and supports a maximum download speed of 40Mb/s for photos and videos.There are many Wi-Fi based transmission systems available on market. However, the experience of using OcuSync is completely different. As Wi-Fi was primarily designed to connect electronic devices locally, it works best when connecting to nearby devices. As it was designed for short range, Wi-Fi systems use low cost transmitters that suffer from weak data links. This means that a Wi-Fi cannot detect weak signals or signals with interference. OcuSync however, uses many cutting-edge communication industry technologies to outperform Wi-Fi in terms of sensitivity, anti-interference, and anti-fading, as well as when flying at high speed. It also supports simultaneous connection to multiple devices.In use, this is the difference between smooth or interrupted transmission, short or long flight range, and short or long recovery times after interference or GPS signal loss. Additionally, since Wi-Fi uses a traditional protocol stack, it takes longer – from several seconds to tens of seconds – to get connected and to re-connect after signal loss But OcuSync uses Cross-Layer Protocol Design, it can establish or re-establish links within one second.As well as point-to-point video transmission, OcuSync also supports wireless connections to multiple devices. For example, you can connect the DJI Goggles, remote controller, and Mavic wirelessly to OcuSync all at the same time. You can also add an additional remote so that you can control the Mavic with two remotes or share First Person View (FPV) videos.
The Phantom 4 Professional is surprisingly tiny. With the legs and propellers folded in, it collapses down to “the size of a bottle”, which is very, very small by drone standards. It makes transportation infinitely easier relative to some of the larger, more cumbersome drones out there. It weighs less than 800g, which will be important for regulatory reasons.
Folded up, it looks rather bug-like to my eyes. A bit like a grasshopper. The propellers are user-replaceable and there’s a “Fly More Combo” pack that includes some extra blades, batteries and a charging hub. The drone will fit inside a dedicated – albeit optional – backpack, meaning less worries taking the drone “on location”. This also comes with the combo pack.
Even the remote control collapses down to a more transportable size. There are grips at the base that are designed to hold your smartphone, and these fold flat against the main body when not in use. The antennae at the top, too, collapse and lock in place to avoid them becoming damaged in transport. A lot of care has been taken to ensure that taking the DJI Phantom 4 Professional on the move isn’t a problem.
LET’S GET THINGS STRAIT
With the recent release of the DJI Mavic, there has been a lot of confusion about weather it’s as good as the Phantom 4. If the Mavic really is the better drone, why would anyone want to buy the Phantom 4 when it costs $200 more? Let’s see If we can find some reasons to go with the Phantom 4 over the Mavic Watch the video above to see the wind test and get an idea of the video quality differences. For more Mavic Info check out the Mavic section
HOW THEY HANDLE WIND
Lets face it, the mavic is much smaller than the Phantom 4, so does that mean it won’t hold up in wind? Not at all. We put both of the drones through extreme winds using a powerful leaf blower and both did better than you would expect. One thing we noticed with the Phantom is that in high winds it tends to drift up much more than the Phantom 4 Professional. we had to reshoot the video a few times because the Phantom would just keep drifting up out of the camera view.
The Mavic seemed to hold its position better, but the video didn’t look as stable as the Phantom 4. This is mostly because the Mavic has a narrower field-of-view, so any movements of the drone are more noticeable.
In most situations, both drones will handle wind better than in this test, because real wind usually doesn’t have as much turbulence. This is more like what the drones would experience if strong wind gusts came along.
If you didn’t know, the Mavic has a completely new camera that’s much smaller than the Phantom 4. The size of the lens on the Phantom 4 is similar to what you would find on a GoPro where as the Mavic is more like a high end Android phone. It’s extremely small, but surprisingly it works. The videos from the mavic don’t come out with as much digital sharpening as the Phantom 4, but if you add some sharpening in post (or maybe turn the sharpening up in the DJI Go app) the video looks (to my eyes) just as sharp. I personally don’t like how much sharpening the Phantom 4 has because it produces more strange artifacts in the images, but I found that those same artifacts don’t exist on the Phantom 4 Professional!
Low light performance on the Mavic is ok, but I think the Phantom 4 beats it by a hair. Both drones go up to ISO 3200, but I would try not to go past 800 or things will go down hill. This is the case for all small cameras, including the GoPro hero 4 and hero 5.
As I mentioned before, the Mavic has a narrower field-of-view (or FOV) compared to the Phantom 4, so shots that you take will look like they were taken with a 28mm lens on a full frame camera. The Phantom 4 isn’t as wide as the GoPro, but it’s still equivalent to a 20mm lens which is approaching the ultra wide lens category. I personally like the Mavic’s FOV because it allows me to get shots that are closer to the action without being “dangerously” close.
I don’t have an example to show right now, but one thing I noticed about flying the mavic is that you can point the camera up when hovering and you hardly see the propellers at all! The Propellers also seem to show up less in forward flight.
The last thing you should know about the Mavic’s camera is that it doesn’t have a fixed focus like the Phantom 4. This means you need to tap what part of the image you want to be in focus while in the DJI Go App. Having a fixed focus is good and bad. It’s good because you can focus on closer subjects and the background will look slightly more out of focus like a DSLR. It can also make the subject that you’re filming appear sharper. The only bad part is, you have to remember to do it, or your images will come out blurry.
Despite its small size, the Mavic controller actually fits in my hands quite nicely. I do prefer the feel of the Phantom 4 remote just because it’s more like a traditional RC controller, but I’m liking the controller for the Mavic more and more every day. Both controllers have the same basic buttons, but the mavic has a dedicated stop button for the smart mode which is really nice if it’s getting ready to run into something that it can’t see.
Here’s where the Mavic controller exceeds the Phantom 4. It has and LCD screen for basic flight info, it charges though micro USB, it has a more reliable connection to the mavic and it’s super small. The only bad things about it are… There’s no way of mounting a tablet to it, and there’s currently no sun hood available.
THE LITTLE THINGS
Right now, the Mavic is new, so things like ND filters and prop guards will take some time to come out. Obviously since the Phantom 4 isn’t new, there’s tons of third party accessories available. One thing you won’t have to worry about with the mavic is buying a case. It’s so small that you could really throw it into any case or bag and not worry about it.
Here’s something you probably never thought about. Most people won’t care about this, but the Phantom 4 does have larger motors and propellers, so you can lift signs, deliver packages, or who knows what else. It’s also big and white, so seeing it when flying line of sight in dark conditions is easier.
WHICH ONE YOU SHOULD BUY
Do you own a decent smartphone? Do you need a sun hood no matter what? Are you trying to lift anything? Do you like shooting video while flying forward? Is portability important to you? Is Price important to you? These are the main questions you should be asking yourself.
For 90% of the population, I think the Mavic is going to be your best bet, but for the other 10% you might want to consider the Phantom 4 (or even the Inspire 1 Pro if video quality is your top priority).
With most devices, going smaller usually means cutting features, but that couldn’t be more wrong with the DJI Phantom 4 Professional. It still comes equipped with all the features of DJI’s larger drones, including front- and bottom-mounted sensors, built-in obstacle avoidance, subject tracking, self-piloted return landings and geofencing to help keep it out of restricted air zones.
If anything, users lose a tiny bit of speed by going with this smaller drone. The DJI Phantom 4 Professional can achieve a maximum speed of 40mph (65kph) in sport mode – a special setting for drone racing, if you want to cut your teeth at the burgeoning sport – while the Phantom 4 can hit a 45mph (72kph) top speed.
The DJI Phantom 4 Professional is a small yet powerful drone that turns the sky into your creative canvas easily and without worry, helping you make every moment an aerial moment. Its compact size hides a high degree of complexity that makes it one of DJI’s most sophisticated flying cameras ever. 24 high-performance computing cores, an all-new transmission system with a 4.3mi range, 5 vision sensors, and a 4K camera stabilized by a 3-axis mechanical gimbal, are at your command with just a push of your thumb or a tap of your finger.
The DJI Phantom 4 Professional may be the first prosumer camera drone with true mass appeal.
While there have been several kinder, gentler quadcopters this year — from the large PowerVision PowerEgg to the compact Yuneec Breeze — the Phantom 4 Professional is really the only one to combine high performance in an ultracompact body. Add in DJI’s full assortment of safety and ease-of-use features and you’ve got a drone that anyone can take anywhere.
Despite the small size, you’ll get nearly the same or better performance as from the company’s top-of-the-line Phantom 4. The new OcuSync encrypted transmission system, for example, gives you control up to 4.3 miles (7 km) away with 1080p live streaming to Facebook Live, Periscope and YouTube through the DJI Go app. The Phantom 4 has a max range of 3.1 miles (5 km) and streams at 720p.
Like the drone itself, the controller is very small, but still has a monochrome screen to give you important flight data. Want to see what you’re shooting? You can connect a phone and mount it just below the control sticks. Also, DJI added a switch to change from RC to a Wi-Fi mode, so you can quickly launch and control the Mavic with only your phone at distances up to 80 meters (262 feet) with a top speed of 4 meters per second (13 feet per second).
For the camera, DJI stripped away what it could of the body and the lens is smaller — a field of view of 78.8 degrees compared with the Phantom 4’s 94 degrees — but it has the same 1/2.3-inch size sensor. It can record 4K-resolution video at 30 frames per second or 1080p at up to 96fps and 12-megapixel photos in JPEG or Adobe raw. And it’s stabilized with the smallest three-axis gimbal DJI’s ever made.
You’ll be able to control the camera with buttons on the controller or with the mobile app. DJI plans to have full HD first-person-view goggles, too, that will give you a 85-degree view from the camera. You’ll be able to control camera tilt by looking up and down and turn your head to rotate the drone.

Let’s get the Phantom 4 Professional up in the air. The 3830 mAh LiPo battery charged in about an hour, using a compact charger that includes two USB ports. This is handy for charging the remote controller at the same time (plus there’s a spare for your phone, which slots into the bottom of the controller).
Speaking of the controller, it too is small. Two handles/phone grips swing outward from the bottom and will snugly hold most standard or even large-sized phones. But don’t try jamming a full-size tablet in there – it won’t fit. Your phone connects to the controller, as with previous DJI remotes, via USB cable.
The remote features a small but clear monochrome screen that displays modes, telemetry and other key features. But it does not provide the first-person view. For that, you’ll need your phone. (Or the optional HD goggles – which in most jurisdictions you will be able to wear only if someone else is the pilot.)
Oh – before we forget – the Phantom 4 Professional streams at 1080p to your phone or goggles, rather than the 720p of the Phantom 4. What’s more, if you’re using the goggles, DJI has managed to make the lag time so short as to be virtually imperceptible (meaning people shouldn’t get queasy).
Forget your phone? You have the option of using the remote alone to fly the craft. Forget your remote? You can use your phone, with swipe gestures, though the range will be reduced. The foldable props slot in with a locking mechanism in mere seconds (and can be left on when the drone is all folded up).
All set? Satellites locked? Let’s fly. Takeoff was smooth, and we lifted off to less than three meters and took our hands off the sticks. (It comes programmed for Mode 2, but you can change it easily). The Phantom 4 Professional hung there like it was glued in space. It was also noticeably quieter than the Phantom 4, therefore much less obtrusive for people who don’t like the buzzing of drones. This is a major difference.
We lifted higher and carried out a figure-eight. Flawless, smooth, and highly responsive. The lower weight of this machine (1.64 lbs, including battery and propeller), make it feel more agile and nimble. In attitude mode, it immediately inspired confidence.
This is a drone a first-time pilot could easily fly.
Because of the reduced weight, the occasional patch of unstable wind threw it for a small bump (something less noticeable with, say, the Phantom 4), but the three-axis gimbal took it in stride. The lighter weight also means great flight times despite the smaller battery size. DJI says you can get up to 27 minutes of flying time with zero wind, and 24 minutes of hovering.
Despite the fact this was a test unit, we just had to try the obstacle avoidance. And so we did – heading at speed toward a tree. Right on cue, the Phantom 4 Professional slammed on the air brakes by popping nose-up, allowing its prop blast to stop the forward motion. We soon had enough confidence in the feature that we flew it directly toward ourselves (please don’t try this – no matter how excited you are by the feature. And yes, it worked flawlessly). The controller also features tactile feedback, so you also get a little vibration to give you another cue.
We also popped briefly into Sport mode – which allows the Phantom 4 Professional to achieve a maximum speed of 40 mph (64.8 kph). Plenty fast enough for most flyers – and still a joy to fly. Even at these speeds, the craft is incredibly responsive and nimble. No, it’s not on the same level as a tweaked-out racing drone, but it is *very* impressive for a consumer/prosumer personal quadcopter.
Don’t like the speed? We tried “Tripod Mode” – which actually limits the speed to a maximum of 2.2 mph (3.6 kph). Yes, that is s-l-o-w. But that makes it killer smooth, perfect for cinematography (or total beginners).
In terms of intelligence, the Phantom 4 Professional picks up where the Phantom 4 left off – adding even more smart features. For example, it can distinguish between people, cars, bicycles, and even animals. And it can track each of them, in a variety of modes: It can follow from behind, lead from the front, track alongside – even orbit the moving subject while keeping the camera locked on. In addition, it can follow someone up a slope while maintaining a pre-programmed altitude above ground level (think following a mountain biker or hiker as they ascend).
Speaking of the camera – the images we took with the test unit were awesome. Using a 1/2.3” CMOS sensor with 12.3 million effective pixels, clarity and dynamic range were excellent. There was real detail in the shadows, and our daylight photos (bright conditions, no filter) didn’t suffer from that washed-out, high-contrast look that occasionally plagues drone shots taken during peak sunlight. You can also roll the gimbal 90 degrees to take a vertical shot – a highly welcome feature.
