An in-vehicle electronic device includes a host, a first camera, and a first driving device. The first camera is moveably connected to the host, and is configured to capture at least one image of an interior of a vehicle. The first driving device is connected to the first camera, and is configured to drive the first camera to slide between an extended position and a retracted position, so that when the first camera is at the extended position, the first camera is located outside the host, and when the first camera is at the retracted position, the first camera is located inside the host.
