Each IP network camera has its own IPwang address, data processing function, and built-in application software. It can be used as a web server, FTP server, FTP client, and mail client. Many advanced IP network cameras also include special functions. , Such as motion detection, alarm signal output / input device and mail support function. Image compression mostly uses the Motion JPEG method. Based on the requirements of IP technology, monitoring requires more secure application software. Transmission of high-quality images in local area networks or other media is subject to bandwidth restrictions. Motion JPEG compression mode is more than H.26l, H Compression formats such as .263, MPEG, and Wavelet are more popular with most manufacturers. The quality of the generated images is continuous and the formats are more suitable. Motion JPEG format fully supports the standard of the web browser, so no matter from any network platform, you can transfer and display data images in real time without additional user-designed software.
The compression methods used by IP network cameras can be roughly divided into H.264, M-JPEG, MPEG1, MPEG2, MPEG4 and Wavelet. Among them, H.264 and MPEG4 are the current mainstream compression methods. From the functional point of view, IP network cameras are divided into no audio and audio. Based on the consideration of the price of the IP network camera and the transformation of the traditional analog surveillance system, another similar solution for remote monitoring is to replace the function of an IP network camera with an ordinary camera and a network camera server. The network camera server, Also known as a video gateway or video server, it has a built-in Web server, which is a dedicated network video and audio access device that uses an embedded operating system to provide a solution for real-time monitoring of images through a standard browser.
MPEG4 compression method and its module IP network camera M-CAM, its main principle is built-in an embedded Web server. Users on the network can use a browser (such as Microsoft IE or Netscape) to view the camera image on the Web server. Authorized users can also control the action of the camera's PTZ lens or operate the system configuration. It also has alarm input and output functions.
