A:AnswerOn the spec page it says Max temp 110. If the temp is 110+ plus the sun directly on it is expect your device to run hotter than the supported temp rating. I believe you would have issues with the unit getting to hot or the feed not working.
A:AnswerI wouldn't count on it. Google and Amazon are competitors in the small electronics marketplace now. Amazon announced not too long ago they're removing Google products (that includes Nest) from their offerings. This is in an effort to push their own products (Amazon owns Ring now). Before that, Amazon removed the Google Play Store and other apps from their Amazon Fire products.
A:AnswerThe hub is made to sit on a shelf. I suppose that you could mount a shelf on the door and hope someone doesn't slam the door and knock it off, but I wouldn't recommend it. In my house, we have them sitting on a nightstand by my bed and on my desk, near the computer in my office. I'm almost always near a hub. The times that I'm not near the hub, I use the Nest app to monitor it on my phone.
A:AnswerI don't know a degree number but I'm including a screenshot from the nest. When I installed the nest I used the included 15 degree spacer to take it off the left wall some

A:Answerthe purchase cost includes 30 days of free service. After that, the company offers a range of service plans ranging from monthly ($5-30/mo) or annual ($50-300/yr). If you don't carry one of the service plans, then several features of the doorbell get automatically disabled (video recording is the primary feature which gets disabled)
A:AnswerNo, because the footage being recorded is stored 24x7 in the Cloud though nest aware which is a subscription based service. Nest aware provides facial recognition so it can distinguish between a familiar face or not, the ability to create specific activity zones by highlighting the area you want to cover, review past activities and receive alerts to your phone.
