WiFi cameras connected via a standard WiFi network function in the same way any normal WiFi-connected device does. The camera contains a WiFi receiver (much like your tablet or smartphone), and gains access to the web through your router's unique SSID (service set identifier). Once your camera makes this connection to the wireless local area network (WLAN), your video data is streamed through a cloud-based server which can then be accessed directly from your mobile device or computer.
This type of connection is the most popular because it enables you to access your video from anywhere with an internet connection. Because of the versatility and range of this connection, it is the go-to connection type for parents looking to check in on their nanny live, or a business owner monitoring their property remotely.
