Vehicle traveling data recorder from the Angle of 100 ° to 170 ° Angle of view, how wide wide Angle is enough? Through a small experiment today, you will find their own answers.

Low how to do the test?
First, we will choose three test vehicle traveling data recorder, (1) 120 degrees 120 degrees, 138 degrees (2), (3); Secondly, in order to make the test results have reference, we chose a about 1 km of the fixed link to effect in the case of actual driving test.
Low three recorder real driving quality / resolution
Respectively in the same section, we use 120 degrees, 138 degrees, 170 degrees Angle of view of vehicle traveling data recorder, the effect is as follows.
 
The greater the Angle from the effect of vehicle traveling data recorder, the shooting range is wider, but the picture may be some fuzzy. (Also differ according to different models of vehicle traveling data recorder)
Low three different perspectives of recorder
 
The recognition of vehicle license plate is the sharpness, the higher the better the results, the recognition of the license plate number test 120 degrees to the normal range.138 - degree of sharpness of vehicle traveling data recorder because itself is better than the other two , 170 degrees of recorder, right in the middle of the car can clearly identify license plate, but due to large distortion can not be located in the edge of the clear identification.
When the actual road test conclusion
1, high sharpness recorder has a great advantage for identifying licence
2, large wide-angle can show more see on either side of the blind Angle
Low in choosing how wide the recorder
1, private cars, 120 ° to 130 ° recorder will do the trick
2, slightly larger models is about 150 ° can choose recorder
3, like buses, choose 170 ° recorder, after all, the visual Angle is wide on the body
When should pay attention to choose
Recorder is definitely not the more the better, the broader perspective of recorder is greater than 160 degrees, there may be false targets, and the distortion is larger, not only the picture looked at halo, and difficult to clear the target to obtain evidence. Recommended when choosing recorder do not geared to pursue big wide Angle, must be balanced consideration to its real effect.
