To connect your camera to your home WiFi and control it from downstairs, here are a few options you could consider:
If your camera is within range of the strong WiFi signal on the top floor, you can use a WiFi extender or repeater to strengthen the signal on the lower floors. Place the extender somewhere in between the camera and the downstairs area to ensure a strong and stable connection.
In general, as long as the camera can connect to your home WiFi, and your phone is also connected to the same network, you should be able to control it from anywhere within the WiFi range, including from the couch downstairs.
