I'm not interested in providing Amazon (or any other company) with a video camera attached to my home. Outside of early-generation battery-powered models, the ones that clients have asked for have seemed to work well if you set up the wi-fi well for them (dedicated 2.4 SSID seems to be the most reliable configuration).

If it were my own home, I would use a wired camera. Many are available with local storage right in the camera, so no need for an NVR if you don't require lots of storage or have tons of cameras.
