home security components would use the same wireless standard to communicate with the main hub, but factors such as power requirements, signal range, price, and size make it virtually impossible to settle on just one. For example, smaller components such as door/window sensors typically use Z Wave or Zigbee technology because they don't require a lot of power and can be powered by smaller batteries. They also operate in a mesh topology and can help extend the range of networked devices. However, neither protocol provides the bandwidth that you get with Wi Fi, which is why it is usually used in security cameras to provide smooth video streaming, and in other devices that require a fat pipe.
