That ability is also somewhat overstated, they need a lot more information about your house than most people have and they need to be in range of your WiFi. Though the first part has become less of an issue with ML/AI.
More importantly though there is no reason to do that when there is already specialized equipment specifically for tracking objects through obstacles that can’t be thwarted by you turning off your router. Starting with things like IR cameras and moving up to the latest cutting edge imaging systems.
I can’t find it now but I saw a video of a system like this being used in the field in Iraq ~20 years ago.
