A small exercise in learning, record = =
The idea comes from station B to learn to share videos, po to link https://www.bilibili.com/video/BV1sY411h72u?spm_id_from=333.999.0.0

First, clarify the requirements:
1. Universal driving recorder (not for a certain model and brand)
2. Without screen (real-time display as unnecessary requirements)

Consider the problem:
1. Installation location
① Front windshield
② Center console
Most of the products are installed on the windshield. I also think ① is the best choice. (2) The scheme will make the whole product after installation lack of aesthetics (the product itself is very abrupt, and the power cord will be exposed to the outside), as well as safety and other issues.

2. Installation method
(1) suction disc
(2) Electrostatic paste 3M glue
I feel that the suction cup method is not very strong, and it will make the product appear insufficient.

The UP owner also mentioned the design inclination angle of the front windshield, which affects the size of the recorder, but it is not a strict regulation, and it is within the usable range. Research on the driver's use of the driving recorder shows that the recording angle should be variable, so the design should be able to rotate the camera, but only the vertical direction is OK, and the horizontal direction is given to the wide-angle lens.

Details:
(1) The product should be as round as possible to prevent dangerous secondary injury.
(2) APP and voice control, do not need physical keys
(3) product feedback mode (visual or auditory) up main selection with prompt light, emmmm .......... I use voice prompt!
④ Consider the location of the storage card slot/power cord jack


Then let's start

Look for some products first ~

Let's have a few drafts.The hand-painted board is very difficult to use.

Then this is the product... Modeling draws lessons from many other products, but it should not matter to practice.

Welcome criticism ~
