Abstract

A network camera includes a capturing unit, a video converter, an audio converter, a microprocessor, and a signal sending unit. The capturing unit captures an analog video signal and an analog audio signal. The video converter converts the analog video signal to a digital video signal; the audio converter converts the analog audio signal to a digital audio signal. The microprocessor superposes and compresses the digital video signal and the digital audio signal and outputs a first universal serial bus (USB) signal. The signal sending unit converts the first USB signal to a wireless USB signal.

Description

technical field [0001] The invention relates to a network camera, a network camera system and a network camera method. Background technique [0002] With the development of technology, the use of network cameras is becoming more and more extensive. However, the existing network cameras do not have the function of video and audio compression, and an external processing device is needed to compress the image and sound signals acquired by the network camera, and then send the compressed signals to the network. Contents of the invention [0003] In view of the above content, it is necessary to provide a network camera, a network camera system and a network camera method with a built-in video and audio compression function. [0004] A network camera comprising: [0005] A camera module for obtaining analog signals of images and sounds; [0006] A video conversion module connected to the camera module, used to convert the analog signal of the image into a digital image signal...
