The view angle of car dvr camera varies from 100 degree to 170 degree. So what angle is enough for you?
  ● Image performance and definition contrast between three recorders
  In the same section, we use DVR with 120 degrees, 138 degrees, 170 degrees shooting angle to test. As a result, the larger the view angle is, the wider the wider the scope of the shooting is. But the picture may be somewhat vague.
        ● Different perspectives between three recorders
Recognition of the vehicle license plate is the better sharpness higher effect. 120 degrees is the normal range to recognize license number. 170 degrees recorder can clearly identify the license number in the central, but is located at the edge of the large distortion can't identify clearly.
  ● Road test conclusion
    1、high sharpness recorder has a great advantage for the recognition of license number.
    2、Wide angle can show more to see both sides.
        ● Suggestions for the selection of recorder lens angle
    1、Private cars, 120 degrees to 130 degrees will be enough
    2、Slightly larger models can choose angle 150 degrees around
    3、For bus, 170 degrees around, considering the wide body
