Indoor camera in active or inactive mode?

I'm considering the installation of an indoor camera, and I'm curious about its operational flexibility. Specifically, would it be possible to have it only active/recording when no one is home? Is there an option to toggle its activation or deactivation as required? Alternatively, is it possible to simply control the camera's functionality by plugging and unplugging it? If so, would it automatically reconnect to the Wi-Fi network upon regaining power? I don't have the ring alarm system.
