DIY Dashcam Lens Upgrade

If you happen to have a Xiaomi dashcam, this one records in 1080P, has a relatively high resolution, and comes with a small screen. You may suddenly get the idea of replacing it with a larger lens.

This is the screen after being removed. It is just a piece of plastic, and only the buttons underneath are touch-sensitive.

This is the screen without the external display, which is the same as the first-generation version.

This is the mainboard. The lens is mounted directly on the mainboard, unlike the first-generation version, where the lens was mounted on a small board that connected to the mainboard through a socket.

This is the camera.

This is the front cover.

The battery has swollen. Since the dashcam needs to have its time reset every time you turn it on after the battery runs out, you can simply remove the battery this time.

The lens housing has been removed.

You can install a base directly onto the mainboard, allowing you to use a C-mount lens.

After adding a larger lens, you can change the electric aperture to manual control at 18–48 mm, and the modification is complete.
