Abstract: A camera module comprises an image sensor having a size greater than or equal to 1/3.06 inch and less than or equal to 1/2.78 inch and a lens module comprising at least five lenses disposed in sequence between an object side and an image side of the camera module. A ratio between a half-image height of the lens module and a total track length of the camera module is greater than or equal to 0.5 and less than or equal to 0.6. A field of view of the lens module is greater than or equal to 100 degrees. An aperture of the lens module is greater than or equal to F1.8 and less than or equal to F2.4. An equivalent focal length of the lens module is greater than or equal to 10 mm and less than or equal to 20 mm.

Abstract: Embodiments of this application disclose a device identification method and a related apparatus, to reduce costs of identifying whether a device that accesses a network is an AP device. The method in the embodiments of this application includes: when a type of the device that accesses the network needs to be identified, obtaining a MAC address of the access device, and obtaining a MAC address of a Wi-Fi hotspot around a network access device; and then comparing the MAC address of the access device with the MAC address of the Wi-Fi hotspot, and determining, if the MAC address of the access device and the MAC address of the Wi-Fi hotspot belong to a same address segment, that the access device is an AP device.
