To all backers,

Thank you for your support.

As we received plenty of repeated questions from you, we decide to create this thread to post answers here. This thread will keep updating to help you solve your problems.

Here are the questions and answers:

Logistics Questions:

We are glad to tell you that all of the confirmed orders have been shipped out. Please check your mailbox or contact us via help@70mai.com if you don't receive the tracking number yet, cause your address or email info needs to be confirmed. We are waiting for your reply.

As the tracking info takes time to be updated, please don't worry about your package. Your package is already on the way to you. And the tracking info will be updated once it arrives in your country.

Common Questions:

Question 1: 70mai Hardware Kit: Where can I find English User manual and how to install the hardware kit?

Question 3: What is the parking surveillance mode?

After the parking monitoring function is enabled, when the device is power off, it will enter the parking monitoring mode. When the car encounters a collision while parking, the device will automatically record a parking monitoring video.

Tapping the windshield or slam the door will not activate the parking surveillance recording.

Question 4: Will 70mai cover the customs fee?

The tax is not included in the shipping cost. We used the selected carrier to avoid the risk of paying customs tax, but there is still a small risk of paying local tax.

However, we can provide the invoice for you to finish the clearance. Please contact help@70mai.com if you need help.

Question 5: Is the 3040*2160+1080P the max resolution for the A800?

Yes, you can use special tool to show GPS info in google maps. Here is the guide:

    Just placed order on Oct 2020 and installed 70mai A800 dash cam including rear cam with the latest version (1.0.6ww firmware). Checked hardware kit installed properly and it is able to set Parking surveillance mode with HIGH sensitivity.

    Ignition On 
    Video recording is working, and all good. 

    Ignition OFF
    It goes to Parking surveillance mode in 5 minutes as expected. Try to simulate the impact for several times and there is NO parking record at all.

    Please fix the issue as soon as possible. Parking surveillance is one of the main features !!

    I recently bought this dashcam (Front and rear) and it's good. I previously had the 70Mai Smart Dashcam pro, so this was an upgrade, BUT there are two things that disappoint me a lot :( and I hope you consider this advice for a future firmware update:

    1- Where is the voice command? With the previous model I was able to say "TAKE PICTURE" and, of course, a photo was taken... I think this option should be available in all supported languages. The camera already has a microphone so it only needs a firmware update! How am I supposed to take a picture while driving? 

    2- Parking Surveillance, maybe one of the main reasons I bought this dashcam, it would be great to park my car and keep both sides under surveillance... But much to my surprise, this is not possible without the hardware kit... Seriously? With the previous model all I had to do was to disconnect the USB and the camera immediately entered into the parking mode... Now if I do so, the camera shuts down... Reading the online manual I found this: "Some vehicles still power the cigarette lighter while in parking. In these cases, the car camera will only enter parking surveillance mode when the auto power off time has been set in the car camera settings". This is great, but after the firmware update I can't even activate the parking mode! 

    Please, 70Mai, this camera is supposed to be an upgrade from the previous model, give us a Firmware update with these two options! Your customers deserve it!

    Dear 70 Mai,

    Sent you email since 2-3 months ago about issue with GPS/ADAS not working, until now there is no reply that has solution and no support to return the unit for a replacement

    Subject:  A800 Speed/GPS and ADAS questions

    Had the A800 dash cam for a few days using 256GB sdcard and updated firmware. Having trouble with GPS/Speed and ADAS.. initially it said calibration completed but it’s not working. Just reset the camera and try to setup again but doesn’t seemed to work even after calibration complete

    Updated firmware and reset the dashcam 3 times already, disabled/enabled GPS and recalibrate ADAS more than 3 times successfully

    But still no ADAS warnings and no GPS speed and location on dashcam

    Want to know if I am doing anything wrong or my unit has defective GPS and ADAS unit?
    How can i get a replacement unit?

    1. How to update firmware? Instructions here say to connect the app to the dashcam. I connect and can configure the dash cam. But there is absolutely no option to upgrade firmware. My firmware is now V1.0.6ww.20200910. Is this the latest?

    2. The rear camera video can play on the 70mai app but when exported to iPhone or Macbook, it cannot play at all in any other player. No such problem with the front camera video.

    3. Can you change the ADAS voice warnings to beep beep beep? It can be very irritating.

    The manual that comes with the camera says MicroSD card to be minimum capacity of 32 GB
    and rating of U1(UHS-1) or above. But this website says "Please make sure that your Micro SD card has U3 and Class 10 logo".

    So it it U1 or U3?

    can video footage be shared directly from the SD Card of the Dash Cam? or does the videos need to be transferred first to the photo album of the mobile phone?

    Since i have updated the firmware to 1.0.9ww that camera came useless. Emergency videos started from every single bump even if it is on LOW sensitivity. But that's not all. The camera starts recording whenever it wants. And as you can probably guess... most important moments are missing. So please give us some hints, when these things will be fixed back to normal ? 

    I am waiting for your respond.
