I have had it for 1 year in an electric car and I have connected it to the OBD port with a low profile OBD to MicroUSB adapter which has a toggle switch on top so that I can easily open/close it. I have done this so that when I park outside, it continues to record even when the car is turned off, while when I park in the garage, I close it so that the 12-volt battery doesn't get drained.

Personally, I would like it to support more memory because with 128GB, which is the maximum, it can hold about 9 hours of video (1080p, while with 1440p it's around 6 hours), so if I park for more than 9 hours at night and something happens, I might lose it (although it might be saved in the emergency folder which doesn't get deleted, but fortunately, I haven't had to use it to find out). In any case, I don't consider this a normal scenario (since most people don't operate it this way, but I'm mentioning it for the 1 person who might want to do the same), so it doesn't lose points there.

The cable for the rear camera fit comfortably and the installation was straightforward and easy.

The video quality is good during the day and average at night, but all dashcams struggle in this area.

One slightly annoying thing is that when it updates, sometimes it loses the settings and generally loses the time... every 2 days, for example, it might lose 1 minute.

The application is user-friendly and you can view the videos on the spot as well as download them for better quality.

The emergency recording seems to also have drift detection because whenever I drift a little when I start quickly and the car spins slightly to the right or left, it captures it and saves it in the emergency video folder, so if you experience hydroplaning, for example, it will record it.

In the end, I am satisfied with the purchase and Xiaomi once again offers value for money.

Very good image both front and back, the only downside and for that reason I give it 3 stars is that when I needed it, it had shut down due to overheating and wasn't working... Plus, you have to buy the extra cable to have the parking mode

Good image front and back. It is almost certain that in the initial placement it will not suit you where you will put it and you will have to move it, which is a little difficult because it does not stick with a suction cup but with adhesive. The front camera does not have much room to change its angle. You cannot rotate the back camera, you have to orient it correctly from the beginning. It does not have a quick access button for the on-off of the microphone, only if you go into the settings.
The WiFi is very convenient, you can directly download any video you want to your mobile without having to remove the SD card. It is not my first one. It is not perfect but 5* due to its price and proportionality with what it offers

The person who will purchase this should know that in order to use the parking surveillance function, they will need to purchase an extra adapter and proceed with a hard-wire connection to the car's fuse box.
