FAQs
Find the answers of most asked questions here.
Why is my memory card not working?
Due to the product characteristics, the memory card of dash cam needs to be formatted frequently, resulting in specific demands on the transfer speed of the memory card. Please use a U1/Class 10 or above memory card (there are more inferior products for this class of card on the market, with poorer durability and performance. It is recommended to use the official 70mai card or TF card from brands such as Longsys, Samsung, SanDisk, Kingston).
Ensure that the stated capacity of the memory card is not any less than 16GB.
Besides downloading the video by connecting your mobile phone directly to the dash cam, what other methods are there to export the image data in the dash cam's memory card?
There are two methods:
1. Turn off the dash cam and connect it to the computer using the data cable supporting USB 3.0 or faster (support mainstream versions of Windows/Mac/Linux computer systems). Once the dash cam is turned on, the removable memory disk will appear on the computer, after which you can copy the needed video or photos to the computer.
2. Remove the memory card from the dash cam and view its contents on a computer using a card reader.
Why does the memory card become hot after the device has been running for a long time?
Possible reasons include:
1. Hot weather: dashcam exposed to direct sunlight. The heat generated by working dash cam is slow to dissipate and the accumulation of heat leads to increased body temperature, hence affecting the memory card slot.
2. The memory card is in the state of continuous reading and writing when working in the dash cam, which will also generate heat.
Things to note regarding memory card heating:
1. If the quality of the memory card is poor and the reading/writing speed is slow, the heating of the memory card will be more severe. Therefore, when purchasing a dash cam, please make sure to also purchase a high-quality memory card with a speed rating that meets the requirements.
2. It is normal for the memory card to heat up, but if the memory card is overheated for a long time, its reading/writing speed and service life may be affected. Therefore, please try to avoid using the dash cam in a high temperature environment and replace the memory card regularly to ensure its reliability.
Why is there a memory card abnormality alert? How can it be solved?
According to different memory card abnormalities, the issues can be addressed with the following methods:
•Low memory card capacity: The memory card capacity supported by this device is 16G-128 GB, please check the memory card capacity.
•Low memory card quality: Video recording generates a large amount of video data, which requires high reading/writing speed of the memory card. Please use memory cards of U1/class10 and above. If the memory card has been used for a long time, the reading/writing efficiency will deteriorate as well, so please replace the memory card in time to ensure the normal operation of the device.
•The memory card needs to be formatted. When a memory card is detected to contain files that were not generated by the dash cam, or is used on the dash cam for the first time, it needs to be formatted.
•The memory card is corrupted. This situation indicates that the memory card’s life span is up, so please replace the card with a new one as soon as possible. Otherwise the dash cam will not work properly.
