Menu screens

Initial firmware out of the box, the menu was all in Chinese only.

Luckily firmware v0.6.4.2444 and above, the menu has English and Chinese.

You can also manually update the firmware by downloading the firmware from Fimi forum here and copy into your microSD card’s root directory.

Please use a UHS3 microSD card as using a lower speed card might fail during the firmware update.

Stable firmware version released on 09/20/2017
1. Add Traditional Chinese and English
2. Add Waterproof case mode: Long press the button to enter after system menu opened
3. Fix the problem of deleting the first file in media library and showing the final file
4. Fix the problem of deleting file causing thumbnails display error
5. Optimize system stability
6. Optimize user-directed interaction
7. Optimize Wi-Fi start when power on
8. Optimize the image white balance

I have updated the firmware. Below are all resolutions, fps and overall bit rate.
3840×2160 30fps overall bit rate of 58.7 Mb/s
2560×1440 30fps overall bit rate of 65.3 Mb/s
1920×1080 100fps overall bit rate of 63.9 Mb/s
1920×1080 60fps overall bit rate of 66.6 Mb/s

    Jeremy Wong · September 22, 2017 at 10:10 pm

    I used the Mi Home app to download and update the Mijia dashcam’s firmware…

Bernard Rosenfeld · September 23, 2017 at 4:32 pm

Can you show us how to connect the csmera to mi home and change Language and update the firmware? Thank you.

    Jeremy Wong · September 23, 2017 at 6:46 pm

    I have updated my review with the manual update links. Maybe tonight will do a short video on how to change the language after update.

Hi bro, can your Samsung Evo+ 64GB UHS3 card write at 100Mbps mode?

    Jeremy Wong · November 30, 2017 at 9:27 am

    I think I can get about 80MB/s+- for the Samsung Evo+ UHS-1 but the newer Samsung Evo Plus or Samsung Evo Select UHS-3 can.

      Jayce Ooi · November 30, 2017 at 10:58 am

      Have you tested it? My Kingston UHS-3 card that can write 80MB/s failed on 100Mbps mode. LOL

        Jeremy Wong · November 30, 2017 at 11:05 am

        Not yet. LOL

          Jayce Ooi · November 30, 2017 at 12:13 pm

          Do test it. And let me know. Want to invest on cards that able to write at 100Mbps mode.Thanks. =)

          Jeremy Wong · November 30, 2017 at 12:15 pm

          Sure thing. Will let you know when I do 🙂

Jayce Ooi · December 1, 2017 at 10:34 pm
