IP cameras are cameras that are designed to hook up to a network, and after they are hooked up to a network they can be monitored from any computer with internet access. You can get a variety of IP cameras with different features and capabilities, and that includes wireless IP cameras and Ethernet IP cameras. The difference between these two cameras is how they hook up to a network. Wireless models can hook up to a network through a wireless connection, while Ethernet cameras need to hook up to a network through an Ethernet cable.
