So Google invested 450 million in ADT?<p>Pocket change for Google, but still a significant amount of money. Perhaps that is a bit too far fetched, but imagine if Google could use location tracking to know who came to your house when you weren't there. Say you got robbed on a Friday night a 10pm.<p>They got footage of the guy, but it's dark outside and he's waring a hoodie, but their software knows WHO was there at that time. Some device (from ADT or Google Nest) could also have BLE trackers as well.<p>Mixed with camera footage and something like Nest Aware applying machine learning to the footage, this deal starts to make sense.
