How good is the obstacle avoidance?

In this DJI Mini 4 Pro Active Track demo I'm pushing the limits and show you the new ActiveTrack360 wheel and try ultra-low tracking below 2m to see how it works out.

Super test of the OA and active tracking Henrik.   Keep up the great work.

I've seen a few crashes in similar environments. It's not 100% accurate.

Especially when trying to descend over an obstacle. in case of active tracking, it won't descend, but if you insist in manual flying to descend, it will try to land  - e.g. on the trees.
You need to be idiot to insist, but you know - murphy's law.

I had one commit suicide in this exact same type environment.

You can see in this video that the drone climbs almost immediately from where you start it.  I believe they need to work on the programming to keep it closer to the altitude you start it. Even with the numbers set very low, mine climbed into a tree, when the actual path was clear.  At 4:44 in his video, you can also see that it will not fly down to keep track of him.

I noticed this when trying to follow my truck too, only it was MUCH worse.  I started it at roof level and as soon as I started moving it climbed so high that it lost me behind trees.

After the good video made by Henrik, I stumbled upon this one: and together they raise the question whether the OA of the Mini 4 Pro really is better or worse than that of the Mini 3 Pro. Any thoughts? Experiences? Updates?

To me it seems there are WAY more videos (than the mini 3) on youtube with the mini 4 flying aggressively into trees and crashing. I don't trust the obstacle avoidance at all.

Hi,
I have some major problems with obstacle avoidance!
Made a video to this problem: https://www.youtube.com/watch?v=s96u6649qR8
Not with small obstacles. There is a problem flying towards a solid carport roof!
The M4P doesn't stop or fly over the obstacle even it will be recognized!
And it can be recreated every time!
Mini 3 pro and Maciv 2 Zoom (APAS on) don't have any problem with this.
I don't trust any more the Mini 4 Pro obstacle avoidance!
regards Heinz

Mini 4 can't recognize branches if they don't have leaves. It is better to stay away from obstacles and not rely on the collision avoidance system. Today, using active track, I managed to bring down the drone due to a collision with branches. It was not possible to avoid a collision because the activetrack could not be stopped from the remote control.

If so, then this is a very serious problem and I would like to hear what DJI has to say about this

Crazy stuff, you can see how the drone flies very slowly against to branches in N mode, but you can't stop it from the buttons on the rc-n2 remote control.

Be sure to buy Care Refresh insurance for your new drone, it will help you save a lot of money in the event of an accident.
