wireless IP camera working principle

The wireless camera is a new type of surveillance camera with a wireless receiver embedded in the Network Camera. It uses WIFI channels and complies with the IEEE 802.11B / G standard protocol. WIFI is a wireless network composed of AP (Access Point) and wireless network card. 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 equipped with a wireless network card can share the wired LAN through the AP. Even the resources of the 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 that is responsible for receiving signals transmitted by the AP. With APs, wireless workstations can quickly and easily connect to the network, just like switches or routers in a typical wired network.
