Do you know what is the highest custom set bit rate it can record 4K + rear cam without errors? I'm using Sandisk Extreme U3/V30 if that matters.
And do you happen to have or know how to get the original ...public/shutdown.m4a sound file which was overwrited by the Olga's voice in custom firmware? I'd like to have the original *bling-blang* sound instead of human voice I think. Thanks.
I'm on Windows device so I don't think I can extract the sound file myself from official firmware package that easily?
50 mbit/s is the most optimal bitrate value. I don't think there is a need to set a higher value.

One very minor improvement I did myself is to color emergency button yellow. It's now just piece of yellow cardboard but I'll order yellow luminous/fluorescent sticker/tape to replace it. I'm doing lot of night time driving(in winter it's completely dark in day time too) so it helps fast to find correct button to press when needed.

If the dashcam is in parking mode(with 70mai smart cable) and I manually power it up with push of a power button and also has this 20min constant power shutdown enabled does it turn off automatically after 20mins? Or stay on forever? Enter back to parking mode after some time? Something else?

Can I use 70mai hardwire kit in place of regular cigarette lighter connection if I connect both ACC wire and +12V wire together to one of the cars ACC fuse with piggy bag adapter? Parking mode seems to rather gimmicky/useless to be honest, and I'd like to keep my cigarette lighter free for other devices. So it should only work as 12V to 5v converter basicly and provide power to dashcam when car is ignited.

Answering to my own questions:

Automatic shutdown setting(5,10,20 min) doesnt work with 70mai hardwire kit even if you manually power up camera after car is shutdown. So if you forget power off the camera it will stay on forever. And when you power it off manually it goes back to parking mode.

I installed the HW kit as it is adviced so I don't know answer to second question about wiring.

Banggood.com still has this camera in stock with reasonable price (about 100 units left in time of writing this message). Aliexpress also have it but price is at least 200% compared to original price, not worth it imo. Hardwire kit and rear camera is cheaper in Aliexpress.

The biggest problem with the A800 is not the low bit rate but the noise suppression. Nighttime video's are of much, much lower quality than daytime vids. The main reason is the over-aggressive noise suppression.
It would be really nice to be able to turn it down or completely off.
The second quality spoiler is the over sharpening, clearly visible as white edges around dark high contrast edges. Both effects are very hard /impossible to correct in post. Really sad because these are just settings which could be modified without any costs.

Download International firmware 1.0.6ww:

How to:
  1. Format the memory card in the DVR.
  2. Remove the memory card. The DVR will turn off. Do not disconnect the charger.
  3. insert the memory card into the PC and delete all contents from the memory card. Not format.
  4. Copy the contents of the firmware archive to the root of the memory card. All eight files from the archive must be located in the root of the memory card.
  5. insert the memory card with the firmware into the DVR, press the far-right button and the power button. Hold 2 buttons until the arrow appears in English.Now you can let go.
  6. Went the flashing process.
  7. after flashing, a green check mark should appear and the DVR will turn off. Firmware is complete. Turn on the DVR with the power button.

Good luck!
does this firmware has new updated version that can use parking mode?

Bright sunny day license plates readability distance is ~15-20 meters with this custom lens and ~50 Mbps bitrate at 4k30 (H.265/HEVC). I guess I've found the proper lens for this device.
Hi Nutsey. Bit of a late reply, but ive ordered this lens for my A800S (im hoping its as simple as removing the old lens and fitting the new one?) Also do you know if the A800S can have modded firmware to increase bitrate?

Thanks
