What initially happen was described in the original post, I have multiple Nest cameras and an outdoor IQ camera just stopped working after ~3 years. Even though there are no external factors that would put it under any stress. I checked the wiring, took the camera down and there was e.g. no damage to it and also no water in the base, it just stopped working.
I searched online and found many others having the same issue(and you can see how true that is as even this post already has 4 kudos) so I contacted support to see if they can help with a repair or replacement and their only comment was a link to the store page to buy a new one. This was a $400 camera I just don't expect them to die after just 3 years of service without even an option of repairing it, especially if it does not have any parts that "use up" e.g. like a battery. And I found it very rude how the customer support just told us to buy a new one.
I have two case numbers (3-9045000033813, 0-5571000033803) we started a second one as they told us to get back to use in the first case but never did.
At this point I honestly want to just warn other customers to not buy into this ecosystem with subpar products that Nest/Google is not standing behind.
My moms home has Ring products which not only already last for over 5 years, the one camera that did fail was replaced under the Ring protect plan without any issue.
