Generally speaking, a 256GB SD card can record about 22 hours of 4K video. Of course, our dashcam has the function of loop recording. When your SD card is full, the dashcam will automatically start the loop recording function, and the new video will cover the oldest video. So in order to avoid the loss of important videos, please remember to backup or save the videos you need in time! If you have any other questions, please feel free to contact us, we will provide you with one-to-one service.

 If you need to play the video on the computer, you need to use a data cable to connect the dash cam to the computer or use a card reader to read the SD card and insert it into the computer. There is no data cable in our package. If you have any other questions, please feel free to contact us.

You don't have to worry, whether your car is equipped with WiFi will not affect the normal work of the dashcam. You can tap the M key to get to the menu to find the GPS and speed watermark and turn it on, so you can see the speed and GPS information in the playback video. Of course, you can also use our dedicated computer player to view the video, as well as GPS and speed information. If you have any questions, please feel free to contact us, we will provide you with one-to-one service.
