Abstract:Wired camera has many defects such as poor mobility and less flexible, so the paper presents a combination of the camera module, WIFI module and stm32 chips to form a WIFI wireless lens Camera. Through researching on theory and entity of camera module as well as WIFI module, this method implements wireless image data transmission to the display device processor by WIFI wireless data transmission technology, LWIP protocol and Socket network programming. When the display device with WIFI wireless network card could connect to the camera's internal WIFI hotspot, it could conveniently complete wireless image transmission, display and storage through a series of operations like connecting to the server, turning on the camera, preserving the image and so on.
