Buying a home? Sellers may use cameras, microphones to spy on house hunters
The trend has been fueled by the spread over the past five years of inexpensive Wi-Fi enabled cameras and mics that homeowners can buy and set up themselves for home security. Motion sensors notify them by text or email that a visitor is in their house, and they can then observe a prospective buyer on a computer, laptop or smartphone through the Internet. Alternatively, they can view a recording later.
