Yes, it was mentioned that the detector would need one antenna for every person, otherwise the algorithm doesn't work well.
I suppose it is more plausible to use cameras and mics, but you'd need to set them up, and they would be more visible. A wifi signal is available in the home, and from my understanding, a regular router can be converted (possible firmware-wise) to be able to detect people. I mean, it may be plausible that a hacker could hack your router (many have back doors and people don't even change the password for the login), see when you are home, and then steal your stuff when you are not there.
