The dash cam, known as the "black box" of cars, has become one of the most popular automotive electronic products in the car owner's mind. But throughout the market, there are many brands and complex parameters, so that the owners of the first choice cannot start. More than 80% of the owners of the first purchase channel are through watching advertisements or friends, but usually because of the lack of related knowledge of vehicle products, buy undesirable products. Next, let's see what we need to pay attention to when we choose a good dash cam.
1. To confirm the appearance of the car according to the model
Due to the different types of rearview mirrors in each vehicle, the individual dash cam looks good, but it can not be placed in the right position in the car by appearance, such as too large the volume to be placed in the rearview mirror and glass, so that the video angle is poor, or the appearance of irregular appearance affects the line of sight and so on. This is not unusual. It looks good. But Ann is not too loud in the windshield, so it's important for the appearance of his car. The correct installation position of the dash cam is in the middle of the inner rear view mirror and the windshield, of course, the small amplitude movement in the left and right upper and lower areas is also possible, but the angle is not too biased, otherwise the video will not have reference, so if a dash cam cannot be installed in the correct position, it will not be worth the loss.
2. Definition
A dash cam is a small video dash cam. The most important index is that the shots are not missed, and the day/night shots are clear enough. In general, a dash cam with 2 million pixel cameras is enough, that is, the Full HD 1080P we often see, but it should be noted that its resolution is 1920 * 1080. The 720P (1280 * 720) dash cam will be more general on the computer, so it can choose more than 2 million pixels and resolution 1080P.
3. Wide angle
Then it is the wide angle of the dash cam, in general, the wide angle of 120 degrees can cover most of the front of the car, even the person who is deliberately facing the front wheel can not hide the scope of the shooting, so the general car angle is 120 to 130 degrees. The position of the two sides of the motive cover, and the wide-angle higher than this degree will make the edge of the picture appear aberration. If the lens quality passes, it will have little effect. If you have a bus, you can only choose more than 150 degrees.
4. Additional function
In addition to the most basic video recording functions, the dash cam has a variety of additional functions, which is more practical is the wireless connection function, and can use the mobile APP to check the video immediately. And other such as blackout continue to shoot, act as parking monitoring, or a key after the accident emergency save function, these functions have a few chicken ribs, after all, parking monitoring cannot monitor the whole car after all, and when a real accident, who will calm down to press the key, and the dash cam will automatically save the meaning, so the meaning is also saved. Not big。 Let's think about the core function.
