SIM Card Insertion Direction (Micro Card)

Device Basic Settings

Since the smart safety helmet essentially functions as a special Android phone without a screen, for operations such as setting its WiFi internet connection, SIM card APN, and internal APP software online upgrades, a screen mirroring software is required, which connects the helmet to a WINDOWS computer via USB, running the mirroring software to make a WINDOWS PC act as its external display, allowing access to the internal Android system. There are many options for mirroring software, for BW620H, it is recommended to use anlink, official download address: https://cn.anlinksoft.com/Note: There is a driver issue when connecting USB to the computer, some computers can automatically install the driver, while others may require manual installation. The standard for judgment is that after inserting USB, the device internal model W20 can be recognized in the lower right corner, as shown in the image below:See: Configure Smart Safety Helmet – Helmet Camera with Mirroring Software, https://www.besovideo.com/detail?t=1&i=127Note: In the mirroring software, the right mouse button is generally used for returning.
