Tachograph selling nearly two years and more, it is the consensus of vendors. We all think, "maybe someday, it became standard on the new car." Tachograph and navigation like navigation beginning to do is single, and later became the standard car. Even in the original car is equipped with front and rear camera tachograph, the cost is relatively low. "
    Determine a tachograph really high quality, reliable, not only to verify the product packaging carefully whether the name, manufacturer, address, telephone service and other parameters indicators, but also from the lens material, wide-view design two aspects make a comprehensive consideration.
    Translucent lens and the ability to determine its sensitivity in low light conditions to capture images. Currently tachograph market mostly uses three types of lenses: all-glass lens, lens and glass resin mixed resin lens. Compared to other lens materials, translucent glass of the best and most sensitive. Therefore, the use of all-glass lens can get better results in the night. And glass lens at high and low temperatures are not easily deformed, with more flexibility and greater security. Generally more than 5 million pixels at resolutions up to 1020P recorder can meet the owners of the usual monitoring needs.
To ensure driving safety, reduce visual blind, tachograph wide-angle to be large enough. But note that, although the wide angle can reduce blind spots, but it is not always better! The larger wide-screen distortion more serious picture of the distance and angle will be distorted and biased. Therefore, when consumers buy tachograph, should confirm whether the real reached a wide-angle data advertisement claimed. The specific method is to observe whether the vehicle can cover both the front left, center and right three lanes. Under normal circumstances, a wide-angle 120 degrees around it can completely cover the three lanes.
