Nest cameras and doorbells are well made and the detection is genuinely good. The platform history is the problem: the developer API was shut down and replaced, features have moved behind subscriptions, and there is no local video path.
Not specified for new work. Where a client already has Nest cameras we will set up the integration, including the developer registration, and explain that this is a platform that has broken its own users before.
We do not sell hardware or carry brands. Bring your list to a design session and we will tell you what is worth buying, what you already own that can stay, and what to skip.
