Hello, the NC450 is the cloud camera, we can access it both locally and remotely; while it does not support cloud storage; and it have been released for years, not a smart home device. 

While for the kasa smart home devices, like smart plug, smart bulb, they can be managed by the kasa app only, no web UI available; except that, they supports the third party, including Alexa and Google. They can work together to make your life smarter. 

Even though they have the same manucfaturer, but there is a lot difference between the product form and the application situation. 

May it help.
