A:AnswerYes, it records to cloud. If you have unlimited internet at home, the you should not feel the effects of a monetary charge. I have 5 cameras and my internet bill has never gone up.
A:AnswerYou would need a subscription for each device. With your purchase plan of 3 devices, you would need 3 subscriptions. You can find more details about the features and services you will get with Nest Aware subscription here : https://support.google.com/googlenest/answer/9233159?hl=en

A:AnswerThey come with 25’ or 7.6m which is a decent length and I have three and never needed any longer and my home is two stories. If you are requiring longer, I believe you can order longer lengths on BestBuy.com and I know for a fact on Amazon. They are not the Nest brand but you may can call them or email directly and inquire if they offer and sell the longer extensions you perhaps need.
A:AnswerWe don't suggest connecting a Nest Cam to a hotspot as this could cause you to go over your data limit. Details on the expected data usage for the Nest Cam can be found here: https://nest.com/support/article/How-much-bandwidth-will-Nest-Cam-use
A:AnswerToo many unknowns to even answer your question. The detail of a fast moving car from any distance, and especially at night, would be difficult for most cams. Don't get me wrong, this is a great cam with great detail, but you'd likely need to look at a top of the line professional system.
A:AnswerThese cameras do not run on batteries, and I am afraid to say that unless you have a back-up generator or power source you will not be able to use them. However, the units work great.
A:AnswerYou need to plug a Nest Camra into an outlet. There are other brands that run on batteries which might be easier for you. The outdoor camera comes with a very long cord & instructions suggested that you could drill a hole into your house wall & plug it in on the inside. I wouldn't want to create a hole in the wall but some people opt to do this.
A:AnswerYes the audio is stored. While the audio quality is much better than I expected, there is a delay in the transmission that can get cumbersome in a two way conversation. But for monitoring purposes, it works well. The distance the microphone monitors accurately will depend on other ambient noise. Our camera monitors the back yard of a mountain cabin. It's located on a second level deck rail. The audio picks up the sounds of crickets and other insects at night, wild turkey flock noises as they work their way through the yard, and the sounds of target practice from neighbors a few ridges away. It alerted the other day when the pest control technician was quietly working around the perimeter of the house. I was pleasantly surprised with the range and quality of both the audio and the video.
