Do you plus this in to an outlet outside?

Yes. But you need to ensure you have sufficient wifi in the location you want to mount the camera.

Yes. Nest cameras plug into a standard household outlet with an adapter input of 100-240V AC, 50/60Hz and an output ranging from 5-15V DC. We recommend using only an electrical outlet equipped with a ground fault circuit interrupter (look for “Test” and “Reset” buttons on your outlet).
