From what I gather, if you need fine-grained location information in a building, you can do this without cameras and just a handful of strategically placed wireless access points.
Less likely to be seen as creepy and such systems already exist.
If you just need 'is a person in this room' or 'how many people are in this room' levels of data, solutions to this problem have existed for decades. No need to over complicate a solved problem.

- bluGill 8y agoIf you are cleaver you can use the wifi signals as a radar and find people/objects even when they don't have a wifi device on them. I'm pretty sure all current technology only works with the have a wifi decide on your person. It is significantly easier to do this and for the most part good enough.
- ConceptJunkie 8y agoSounds far-fetched to me. If you are cleaver, you are also likely to get stuck in a coffee cup billboard or Eddie Haskell will trick you into insulting your Spanish-speaking friend.

Not only can you detect motion and objects through physical mass using WiFi spectrum with a properly equipped device, you can detect if someone is breathing. “What's more, this "Time Reversal Machine" technology is essentially just some clever algorithmic work with little burden on the processor, so it can potentially be added to any existing WiFi mesh routers via a firmware update. In other words, security system vendors should take note.”
- econochoice 8y agoIt doesn't. There are methods that do not require a person to be carrying a WiFi-enabled device for location tracking.
- daveFNbuck 8y agoDon't those require more equipment than just access points?
