Good evening, if someone can help me, I plug the camera into the USB in the vehicle and nothing happens, how exactly do I use it?

I already had the same camera and it stopped working, it froze and the SD card became irreparable, so I had to throw it away. It doesn't have a battery, so it can withstand heat without the risk of exploding. At most, it might break like my old one, but it's very difficult to remove the old one afterwards because the glue solidifies and it requires a metal(!) scraper to remove it. With such a price, you can give it every 4-5 years 20 euros to replace it.

I also have this product. I have bought it twice and I will buy it for the third time. My previous two cameras have broken because I leave them on the windshield in front of the mirror permanently, and as soon as it gets hot in the summer, it gets blocked and one plays the video, the other stops. It keeps doing this continuously, even if the weather gets cold. So, I go through the process of buying a new one. This summer, I will put an old one on before the new one breaks, which I am thinking of buying. I have it connected to a screen in the car and I watch it there, constantly going in and out. It also has settings where you can make the videos record for five minutes, and when the card is full, it deletes the old ones and starts with the new ones, meaning it cycles. You don't need to delete them yourself

It is a good camera, you just need to update the time and date it records if it is not directly connected to an application. It is very important that you can save the specific video you want

It is a recorder that works when the Android sound system is functioning (having power in the USB).
ADAS on the Android sound system through an apk located in its built-in memory.

For the money, it's just fine; I simply have it plugged in and it records. If needed, you can remove the memory and see what it has recorded on a mobile or PC. Note that it saves one-minute videos that take up 160MB each, so it requires fast memory and a fast card reader.

Edit. After 2 years, I needed to view a video, and the memory had become corrupt. It could be the memory or the camera's fault. The issue is that I had no way to realize this beforehand. Also, when I turned off the car, the camera stopped abruptly (it has no battery) and does not save the last few seconds, so in the event of an accident where the car shuts off, it is useless. The corresponding 70 mai - xiaomi, which has a battery, first saves the video and then shuts down. And once when my card became corrupt again, it notified me with an audio message. Of course, we're talking about a camera that is around 100 euros, but you get what you pay for.
