What is the meaning of the network transmission protocol supported by the network camera?

TCP/IP Protocol TCP/IP (Transmission Control Protocol/Internet Protocol) is the Transmission Control Protocol/Internet Protocol, which uses the IP protocol to provide connection-oriented network services and is designed to provide a reliable end-to-end transmission over unreliable Internet. TCP/IP defines the criteria for how electronic devices connect to the Internet and how data is transferred between them. It is also the protocol we use when surfing the internet. For network cameras, this is the most basic protocol. It often uses its reliability to transmit network camera control commands, such as PTZ control, 1/O device control commands. However, TCP has a large overhead in transmitting audio and video streams with strong real-time performance. If the network is unstable, the phenomenon of audio and video jitter is significant.

HTTP protocol HyperText Transfer Protocol (HTTP) is a hypertext transfer protocol that sets rules for files (text, graphics, sound, video, and other multimedia files) running on websites, and specifies the communication rules between the browser and the World Wide Web. The protocol runs on the top of the TCP/IP protocol suite. The network camera can use the HTTP protocol to control the network camera on the external network. It is very convenient to transmit audio and video data over a complex network.

TCP Protocol Transmission Control Protocol (TCP) Transmission Control Protocol. In the Internet protocol suite four-layer protocol, the TCP layer is a transport layer above the IP layer and below the application layer. The role of TCP is to split the data stream from the application layer into segments of appropriate length.

The ICMP protocol ICMP (Internet Control Message Protocol) is an Internet control message protocol. Used to pass control messages between IP hosts and routers. The control message refers to the network's own message, such as whether the network is unreachable, the host is reachable, and the router is available. For user data transmission plays a role.

UDP Protocol User Datagram Protocol (UDP) is the basic network transmission protocol. It uses the IP protocol to provide network connectionless services. It is often used to encapsulate real-time network audio and video data, even if packet loss occurs during network transmission. On the client will not greatly affect the audio and video browsing.
