Working principle of 4G wireless camera: 4G wireless camera is a new type of surveillance camera with wireless receiver embedded in the network camera. It uses a 4G network and complies with the IEEE802.11B / G standard protocol. 4G is a wireless network composed of APs and wireless network cards. An AP is generally called a network bridge or access point. It acts as a bridge between a traditional wired LAN and a wireless LAN. Therefore, any PC with a wireless network card can share the wired LAN through the AP. Even the resources of a wide area network, its working principle is equivalent to a HUB or a router with a built-in wireless transmitter, and the wireless network card is a CLIENT end device responsible for receiving signals transmitted by the AP. With APs, wireless switches can quickly and easily connect to the network, just like switches or routers in a wired network. In short, when a wireless AP or wireless router is connected to one end of the switch, one or more wireless cameras are installed within the signal coverage of the wireless AP / wireless router to form a simple wireless video surveillance system. The display and management are realized by the computer in the local area network, and the PTZ control signals are also transmitted wirelessly. If the wireless AP or router is connected to the Internet, after performing dynamic domain name resolution and port mapping on the wireless camera, remote audio and video monitoring can be achieved. ? 4G wireless camera use description: The scope of application is for criminal investigation, technical investigation, economic investigation, anti-drug, anti-smuggling, political security, national security, security and other departments, as well as on-site negotiations, television broadcasts, film and television command and other places. ? 4G wireless camera operation process: 1.
