Although the dash cam is quite practical, many car owners are unwilling to spend thousands of yuan to install it at 4S stores. However, buying it online and installing it on their own doesn't seem like the right place. Moreover, it can easily distract the driver's attention and pose certain driving safety hazards. Today, the Xi'an tachograph manufacturer will introduce to you how to install the tachograph. Come and observe.

　　One issue is the location of the installation of the dash cam. Usually installed in the position of the interior rearview mirror, connected to the rearview mirror, and there is another type installed on the back of the interior rearview mirror. These two positions are the places that most car owners choose today, because they can avoid affecting the driver's line of sight. Even on rainy days, the wiper's back and forth movement will not affect its normal shooting. When installing, you also need to adjust the angle by looking at the image on the dash cam screen, otherwise if it cannot be captured, it will be installed in vain.

　　The second issue is the wiring problem of the dash cam. Nowadays, there are two wiring methods for driving recorders. One is to connect one end to the cigarette lighter plug, and the other end to the driving recorder. Although this wiring method is very simple, it looks quite disorganized. And the other type is connected to reading lights, which is a relatively concealed wiring method, with almost no visible lines in the car. However, to install this method, professional personnel are required to install it, otherwise it is easy to make small mistakes.

　　Thirdly, there is a memory issue with the dash cam. As is well known, when the memory is full, you can no longer store videos. At this point, you need to format the memory card before continuing to use it. Nowadays, many driving recorders have an "overwrite" function. Once the memory is full, it will automatically overwrite the previous driving records, so that there will be no problem of the memory being full and unable to continue using it. But using this method, the original video data will be lost, and if there is important data, it still needs to be saved in advance. And when choosing a memory card, it is important to pay attention to storage capacity and read/write speed, not too large or too small. Generally, the storage capacity of 32GB and 64GB is sufficient.
