  • Please release a 2K DVR app for universal Android head units.

Adas is fully useless so don't worry about it. It's just a video recorder. It didn't react on pedestrians. It useless in traffic. It's low quality camera.

I would not say it is useless, but I consider it as a gadget. The name ADAS is commonly known, but in this case it should not be called ADAS which means "Advanced Driver Assistance System".
In this case it is a "Driver Warning System". And it is not 100% reliable. Much less than 100%.
But as such it can still help by giving you warnings, but do not rely on it and don't get distracted by it.

I also have other Chinese USB DVRs, and I know that the simple ADAS for general Chinese DVRs with the same lineage, including the DUDUAUTO USB DVR app, only respond to the distance from the car and lane. I think it would be more useful if these ADAS responded to pedestrians, motorcycles, or traffic signals, but it would require additional processing power from the head unit. I know that some DVRs and mirrors with built-in ADAS have systems that address these, but I have heard that their accuracy is not impressive.
A poor ADAS would not be extremely beneficial, but I don’t think it would be a disadvantage either.

While I can't say for certain that the camera on the DUDUAUTO 2K DVR is high-performance, I believe the HDR works well, making it more resistant to backlighting compared to cheaper Chinese USB DVRs.

My camera's firmware version is CarDvr_335_0.0.17_FDUDUAUTO20240325_01, so the file you shared seems to be newer than that. Thank you.
What are the updates?
It seems that I do not have permission to download files from this forum.
A pop up saying 'You are not allowed to download files' appears.

    Gatolab you can search for that file in dudu telegram. Should be easy to find it there by name.
    As I can see the size of firmware for this dvr(4Mb), everything is calculated by dvr app on the headunit.
    Maybe my settings(everything turned on and starts at 30km/h) are wrong or I need to update firmware on dvr, but only sound notifications I get from it when a car Infront starts moving. I find that useless.

    I already searched Telegram. When I looked for "cardvr," it seems that version 335_0.0.17_F is the latest one available, and I couldn't find 335.0.0.18_F shared by Chubaka885. Thank you.

    The HD DVR app worked stably with the DUDU 2K DVR camera, but the ADAS warning sound was only a BEEP. Since the DVR 2K app offers both a BEEP and voice alerts for ADAS warnings, I had been hoping to use the DVR 2K app instead.

    Up until now, I had been enabling the ADAS functionality in the HD DVR app to display ADAS on the DVR 2K app. However, enabling the ADAS function directly in the DVR 2K app caused frequent crashes, making it impractical to use.


    I suspected that the DVR 2K app was missing some backend functionality necessary for it to operate on a generic Android head unit, and it seems that the missing piece was the "DUDU DVR Service."

    When I installed the DUDU DVR Service, the HD DVR app was automatically uninstalled, which suggests that the service includes alternative functionality to replace the HD DVR app. If this assumption is correct, I would like the DUDU DVR Service app to be bundled with the camera for users of generic head units that are not DUDU head units.

    Since I have not driven with the DUDU DVR Service installed yet, I have not confirmed whether the ADAS function in the DVR 2K app now operates stably and correctly. However, during ADAS calibration, the crosshair now displays correctly at the center of the screen, so I am optimistic.

      Gatolab Permissions have been updated,Try again please

      Gatolab For using the DUDU 2K DVR on a generic Android host, you need the universal version of the APK.
      DUDUDVR_2K_universal.apk

      Gatolab разрешения исправлены, попробуйте загрузить снова.

      Thank you, YAOXILONG and Chubaka885.
      I will start using the files you have provided from tomorrow onwards.

      I am reporting the result of installing the DUDU DVR Service to enable full functionality of the DUDUAUTO 2K DVR on a general Android head unit, which is not running DUDU OS, and the DVR 2K app.

      All functions, including ADAS, worked stably and properly. When I selected the voice alert option in the DVR 2K app’s ADAS, it started to give voice warnings in my country’s language correctly. My head unit uses Google’s TTS for this. Since I have never used Toppal, I am not sure whether voice alerts will work with Toppal.

      Additionally, the coordinates and speed, which had never displayed anything other than 0 before, are now being displayed correctly. These coordinates and speed are also correctly included in the recordings on the TF card of the camera itself.

      I just tried DUDUDVR_2K_universal.apk.
      It prompted me to install the DUDU DVR Service.
      However, after installation, the displayed UI was the same as the HD DVR.
      It seems that the speed display is incorrect.

        I just tried the firmware FW_CarDvr_335_0.0.18_F_DUDUAUTO.
        The update instructions mentioned checking the LED blinking pattern, but I couldn't find where the LED is located on the DUDUAUTO 2K DVR device.
        For now, I wrote the firmware file to a microSD card, inserted it into the DUDUAUTO 2K DVR, powered it on, and waited for one minute before checking.
        I confirmed that the version number was updated.
        However, I am not sure what changes were made. I would like to have a changelog.
        Thank you.

          Gatolab You must understand the firmware of the 2k recorder is not developed by Dudu team. Dudu team if we can say so, only sells it. The firmware updates are provided by the manufacturer of the recorder. And if they don't give a change log, Dudu team cannot provide one to you.

            MihaiFlorin if dudu selling it under their name then they are responsible for it and can't refer to third party company to avoid any questions.

            For example I have few questions about it:
            Also why this dvr cannot be updated through app?
            Does it have any other notifications except that the car in front start moving? Because I turned on everything but have only this.
            Why we can't see SD card from headunit file browser?

            I tried uploading a video to this forum, but even smaller files than the displayed upload limit are actually rejected.

            The voice is in Japanese.

            In the DVR 2K app, the Lane Departure, Forward Collision, and Front Car Start alerts all worked with proper voice notifications.
            When the sensitivity is set to High, there are so many warnings that it becomes almost annoyingly noisy.

              Gatolab is there any chances after firmware update on dvr? Will try to test my after update

              Gatolab so I updated my adas from 15 to that 18, but it looks like to get any other notifications you need to use voice instead of sounds. Start to use voice notifications, will see how it goes
