Дронът DJI Phantom 4 – изненадващо интелигентен, бърз и безопасен Дронът DJI Phantom 4 е по-добър, по-интелигентен, по-бърз и по-безопасен от всички свои предшественици от серията Phantom, както и от всички други дронове на пазара. Това се дължи на множеството иновации и модификации по квадрокоптера, част от които са Obstacle Avoidance системата, функцията ActiveTrack, режимите Tapfly и Sport, Quick Release пропелерите и т.н. DJI Phantom 4 е първият дрон, който разполага с интегрирана система за избягване на удари, сблъсъци и стълкновения с други обекти. Системата носи логичното име Obstacle Avoidance system и включва 4 камери и два ултразвукови сензора, които позволяват на квадрокоптера да идентифицира потенциални заплахи като стени, огради, дървета, комини, електрически стълбове и т.н. Ако бъде открито препятствие или заплаха, дронът САМОСТОЯТЕЛНО ще предприеме едно от следните действия: 1. автоматично ще промени височината, на която лети, за да предотврати сблъсъка, или 2. ще прекрати полета си и ще започне да кръжи на място, ако не може да избегне заплахата. Другото голямо нововъведение при Phantom 4 е функцията ActiveTrack. Тя позволява на дрона да следи движещи се хора и обекти, използвайки напреднала технология за разпознаване на образи. Това означава, че Phantom 4 няма нужда от GPS тракер или гривна, за да може да следи и записва всяко Ваше движение, докато Вие спортувате или се забавлявате! За да използвате режима ActiveTrack, първо трябва да го активирате през приложението DJI GO на Вашия таблет или смартфон. След това трябва да маркирате човека или движещия се обект (автомобил, влак, велосипед, лодка и т.н.), който искате да следите, и гонитбата може да започне. А най-якото е, че докато използвате ActiveTrack режима, е активна и Obstacle Avoidance системата, която ще предпазва дрона от разбиване. Tapfly е напълно нов, уникален режим, който позволява на DJI Phantom 4 да лети там, където го насочвате с пръста Ви. Използвайки този режим, можете да зададете посоката на движение на дрона само с едно докосване на дисплея на Вашия таблет или смартфон, без да е необходимо да използвате дистанционното управление на дрона. Obstacle Avoidance системата продължава да бъде активна и при този режим, което означава, че Phantom 4 автоматично ще избягва препятствията или ще кръжи на място, когато не може да открие сигурен път. Спортният режим е нещо, което определено ще се хареса на любителите на високи скорости. Той позволява на Phantom 4 да лети с невероятните 72 км/ч (20 метра в секунда). Имайте предвид, че когато квадрокоптерът е в режим Sport, Obstacle Avoidance системата не е активна и спирачният път на дрона е значително по-голям. Phantom 4 идва и с изцяло нови Quick Release пропелери (перки). Те са много по-лесни за монтаж от самозатягащите се пропелери на неговия предшественик Phantom 3 Professional v3.0. Освен това имат много по-здрав и сигурен захват, който позволява на дрона да се ускорява, да лети и да спира по-бързо, както и да бъде много по-отзивчив по време на полет.

The DJI Phantom 4 is the latest premium product from popular Chinese drone manufacturers DJI. The Phantom 4 builds on the Phantom 3 series (Phantom 3 Professional, Phantom 3 Advanced, Phantom 3 Standard and Phantom 3 4K), adding much sought after features such as obstacle avoidance, visual subject tracking and improved camera & gimbal. Users looking for professional quality video from an easy to use quadcopter need look no further. In this review of the new DJI Phantom 4 we’ll cover everything you need to know to make your next drone purchase an informed one. Table of Contents DJI Phantom 4 Review Jumping right into the tech specs, and what’s good/bad about this drone should give you a good idea of what you’re getting into. DJI Phantom 4 Tech Specs: - Camera – 1/2.3” 12 M Pixel - Video – 4K at 30 fps / 1080p at up to 120 fps - Photo – Single shot, burst (3, 5, 7 frames), bracketing, timelapse, HDR - Flight time (hover) – 28 minutes - Flight time (normal use) – 25 minutes - Battery capacity – 5,350 mAh - Weight (with props and battery) – 1,380 g - Maximum horizontal flight speed – 44.7 mph (72 kph) in Sport Mode - Maximum vertical ascent speed – 13.5 mph (21.6 kph) in Sport Mode - Maximum operating height – 6,000 m - Obstacle sensing range – 0.7 to 15 m - See the price on Amazon here The Good: - High-quality photo and video that professionals would be happy with. - Longer flight time. - Advanced features like object avoidance and tracking are a big leap forward The Bad: - Price. All these features come at a cost. - Battery incompatibility with previous versions - Sport mode drains the battery quickly and cannot be used with automated flight features Unlike the Phantom 3 series, there is currently only one version of the DJI Phantom 4, which makes selection a lot easier. The list of upgrades over the Phantom 3 Professional (which itself is still a fantastic quadcopter) really is phenomenal. The Phantom 4 has a whole host of upgrades all working together to provide better quality video and a simplified user experience. Video Features: - The gimbal has been reinforced and integrated into the bottom of the shell. There is also a new upgraded camera, which works with the gimbal to make videos smoother and sharper than before. 4K ultra HD at up to 30 fps and 1080p at up to 120 fps slow motion means you can produce high-quality footage of what matters to you. - The props have been raised to stay out of the way when filming, which is great if you are going for a cinematic shot. This goes a long way to making videos that previously would have required a custom-built and extremely expensive drone. - Vibrations that would normally make shots blurry have been minimised by the re-designed composite unibody, which is strong and lightweight. - “Tap fly” allows the drone to fly in the direction you want, with just a tap on the screen, all whilst avoiding obstacles and with no need to use the remote control. - “Active Track” will track a subject based on what it looks like, whereas before it simply tracked the remote. This is a huge leap and really highlights how advanced the Phantom 4 AI is. Flight Features: - 5 minutes longer flight time over the Phantom 3 Professional, you can now stay in the air for 28 minutes thanks to the more efficient motors and larger battery. The Phantom 4 (1380 g) is 100g heavier than the Phantom 3 Professional (1280 g), but almost all of this weight has gone into a larger battery. - A top speed of up to 44.7 mph (72 kph) compared to the already rapid Phantom 3 Professional, which is capable of up to 36 mph (57.6 kph). To achieve this, DJI has introduced a new “Sport mode” for high-speed flying. The Phantom is now safer and more reliable, but we’re not convinced that this will be the end of accidentally flying into trees and buildings. The obstacle avoidance only works when you are flying straight forward, as there are no cameras to the rear and sides. It’s worth keeping this in mind and understanding that the obstacle avoidance won’t detect power lines, tree branches or other objects that are small or low density. That said, the obstacle avoidance system will stop the quadcopter before it hits most solid objects and is certainly a leap forward when it comes to making aerial videos more accessible. The feature we were most excited about was “Active Track”. As mentioned before, this will track a subject based on what it looks like and so is ideal to capture video of yourself and your friends while doing an activity. This is set to be the next level of action camera, automatically videoing you whilst you mountain bike, ski or even kayak. In practice this does work, but you need the right conditions and need to avoid other people. The drone will lose you if you go behind an object/around a corner and can get confused if there are multiple potential targets, don’t try this in a crowd or your drone might follow someone else home! The battery may be bigger and give you a longer flight time, but this also means that the Phantom 4 is not compatible with batteries from previous versions. Granted, this is only an issue for people who own another Phantom, but we are disappointed that DJI didn’t make the Phantom 4 compatible with the Phantom 3 batteries. The verdict – is the DJI Phantom 4 for you? DJI have clearly put a lot of time into making the Phantom 4 easy to fly, whether you have previous experience or not. The Phantom 4 is sure to shake up the drone market and we hope that the object avoidance and tracking are further improved in the next model. A whole host of upgrades over the previous Phantom 3 Professional makes this a very worthwhile upgrade. If this review of the DJI Phantom drone was useful to you, we’d love to hear it!
