I juste received my dash cam, amazing !
Just one problem, why download dash video via wifi is so slow ?
My phone is RedmiNote5 , i tried donwload video with the VifoHotspot-5G of my dashcam
3minutes for 60Mb.
Something strange, when I see live of my dashcam, the speed is around 1.2Mb/s (good!)
But when I donwload data from sd card via wifi, is around 350Kb/s. If I read the sdcard directly on my laptop i get more than 5Mb/s for sure!
Anyone has this problem ?

Maybe try not using the 5G...

I have had up to 12MB per second from the A129 Pro to my computer, average over a file. Phone wifi might be limited by the wifi channel width the phone can use, 5G isn't always the fastest.

Need to remember, these are big files, if you want to access a lot of them then transfer the memory card!
Downloading one or two files to the phone as a backup of something important, or to share it, should be feasible though.

I really want to avoid to set/unset the sd card and I just expect to be able to tacle easily one or two files after a "bad event" (by wifi!).

Dismount the whole camera and connect it to the PC...

After some tests, i can conclude about WIFI for my phone (RedmiNote5) :
*Wifi-5G is very slow : ~300kO/s => bug with my phone (i can reach 4Mo/s with my own internet) ?
*Wifi-2.4G quite good : ~2.2Mo/s => enough for what i'm expecting to do with this dashcam :)


PS : like Smiley1081 suggest i'm expecting "Dismount the whole camera and connect it to the PC... " to read the 3.5 harddrive hided inside o_O

That is a bit disappointing, but at least it is usable in emergencies.

I normally do as Smiley suggested and plug the camera into the computer, but it is still not fast because the camera is a very slow card reader, you will get 20MB per second maximum. If you have a USB 3 UHS card reader then that can be 4x the speed of the camera. For me the camera is fast enough.

Yes I understand, but I spend a lot of time to select the best compromise for me :
=>A119 V3 best quality video for cheap price but no wifi, so you have to unset the SDCARD when you want to get one or two video (i don't want!)
=> A129 Plus Duo lower video quality (I confirm !) but wifi and a second camera. I bought this one especially for the wifi (the rear camera helped me to take the final décision), that's why i'm quite disapointed by the wifi speed.

Another fact, i can report : The wifi speed can reach 5 or 6Mo/s when you do live video, so clearly like Nigel suggest A129 Plus Duo read sd card very slowly.

As I said before, I almost never remove the SD, I remove the whole 119V3, the contacts a more robust.

10 years, many dashcams
I have always taken the memory card out, though at times i have also take the camera out as i had so many cameras, and the little cards are a pain to handle in the car.
But ! always taken the memory card out to read it in my card reader, that way i can also play footage from the memory card directly, that is not for sure you can do if you play from a devise in mass storage mode.

Even 100 mbit 4K /60 footage from my action camera i can play from the memory card in the reader with no lag, and copying footage off i get upwards of the memory cards mas speed of 80 Mb/s
Which are a big deal for me if i have to copy several GB of footage.
But just browsing a memory card and grabbing a single file or two noow and then, that you can do via the slow wifi on most cameras or a camera in mass storage mode, which is also slow compared to a good USB 3.0 reader like mine.
