Horizontal comment on four mainstream tachographs

speaking of tachographs, they can be regarded as the most popular product in the current automotive market. More and more car owners add tachographs to their cars. The main purpose is to truly restore the scene of the accident, and it is the best tool to judge the accident and trace the escaping vehicles. However, at present, there are many kinds of products in the dash cam market, and the quality and actual effect of the products are also uneven. Many consumers buy some low-quality and unqualified dash cams, which not only do not play their due role, but also increase many safety hazards. Today we will have a horizontal evaluation and test of dash cams

first of all, it should be noted that the products we choose are several products with manufacturer's warranty approval currently sold in autohome mall, and considering the factors of price and sales volume, we choose basically medium and low-end products with a price of less than 1000 yuan. After investigation, this price range is the largest sales volume in the current market. To sum up, the tachographs participating in this horizontal evaluation are Papago P0, Kuaiyitong V10, DOD tech v660 (hereinafter referred to as DoD) and skylook dt-660s (hereinafter referred to as skylook)

at present, the dash CAM products on the market are mixed. This paper selects four products with good sales in autohome Mall for PK. Therefore, all conclusions and opinions this time are based on the four products in the article, and are not aimed at other products other than these four products

next, let's introduce our horizontal evaluation rules. Of course, the most important thing for the dash cam is the definition of the image, but at present, many products are basically the same in terms of camera selection, so we focus on the comprehensive strength. For this purpose, several test items are specially set, including the appearance size, workmanship, support fixing method, storage method, daytime shooting effect, night shooting effect, tunnel display effect (i.e. light and dark change display effect), and night encounter strong light display effect

dash cam horizontal evaluation comparison item item name Description Product appearance specification is not counted as the final result fixed method is not counted as the final result product workmanship is counted as the final result storage method is counted as the final result daytime shooting effect is counted as the final result nighttime shooting effect is counted as the final result through tunnel shooting effect is counted as the final result nighttime strong light shooting effect is counted as the final result hand on the interface is counted as the final result screen definition calculation Make the final result. The length of the power cord is calculated as the final result. Whether the built-in battery is calculated as the final result. The wide angle of the lens is calculated as the final result. Scoring rules: 5 points, 4 points, 3 points, 2 points, 1 point

item introduction and Description:

for these test items, we are set for daily practical use. Many friends think that the appearance of the product should not be considered for the dash cam, However, the size of the dash cam will affect the driver's line of sight more or less. The length of the power line is one of the key items for comparison. Strictly speaking, the power line of the dash cam should be hidden along the interior trim panel, so the length of the power line is particularly important

appearance and size specification: if the volume is too large, it will relatively affect the driver's line of sight, so the smaller the volume, the higher the final score

product workmanship: in order to distinguish the current rough and shoddy products in the market, the four brands we choose are relatively well-known in the industry. The same price and the same level of workmanship, the higher the rough score is, the lower the score is up to 100000 times. On the contrary, good workmanship can improve the comprehensive score

storage mode: in most cases, there are two storage modes, mirco SD and SD, which realize the versatility of the universal experimental machine. In terms of convenience and versatility, SD card can directly plug and unplug laptop. Why is the sales volume of the machine so large, while mirco SD needs an auxiliary card to connect to the computer, that is to say, the relative score of using SD card is high

fixing method: most products use the suction cup method, and some products use the adhesive method. Relatively speaking, the suction cup is more convenient, but the firmness is slightly poor, while the adhesive method is just the opposite

daytime shooting effect: select the same vehicle and fixed test route, place the four tachographs in a fixed position in the vehicle to shoot the normal driving conditions in the daytime, and judge the definition and identify the license plate number through the final video

night shooting effect: select the same vehicle and fixed test route, place the four tachographs in a fixed position in the vehicle to shoot the normal driving conditions at night (with slightly poor visibility). The universal tensile testing machine is needed to pass the final auto parts, mainly including: the video judgment clarity obtained from the rubber products on the car, identifying the license plate number, etc

shooting effect through the tunnel: also known as the alternating effect of light and dark, select the same vehicle and fixed test route, place the four tachographs in a fixed position in the vehicle, shoot the video when entering and leaving the tunnel, and judge the clarity and identify the license plate number through the final video

shooting effect in case of strong light at night: select the same vehicle and fixed test route, place the four tachographs in a fixed position in the vehicle to shoot the situation of strong light exposure at night (most of the time to the vehicle's high beam), judge the clarity and identify the license plate number through the final video

how easy it is to use the menu interface: whether it is easy to operate the dash cam or not determines the final score

screen definition: observe the display effect of the dash cam screen, and finally get the score

power line length: in order to avoid the power line interfering with the driver's driving, most of the power lines of the dash cam will be safely hidden above the center console and in the right interior trim panel, and then connected to the cigarette lighter from below. If the power line is not long enough, this operation cannot be completed

whether there is a built-in battery: in many cases, the vehicle will automatically power off in the event of a collision, so the dash cam will turn off accordingly. If there is a built-in battery, it will continue to work, not affected by the power supply. Most of the built-in batteries of the dash CAM use lithium batteries, and the high temperature resistance is above 100 degrees Celsius. Therefore, long-term exposure to the sun will not cause an explosion

wide angle: in order to record the process of accidents and scratches more comprehensively, the use of wide-angle lens will greatly increase the shooting range

for each product, we will make a separate evaluation, score according to each item, and finally get the total score as the result. We try to be considerate, in order to give each product a more comprehensive evaluation, so that for many consumers, they can choose according to their own needs
