Caller ID is NATIONWIDESECUR. I knew it was a scam but I answered it anyway because I wanted to know which scam it was. There was about 5 seconds of silence, several clicks, then Andrea Pierce (probably a robo-call) came on. Andrea explained they were looking for a few homes in my area to give a free Wi-Fi security system to. All I was required to do was put up a small sign in my yard. She asked if I would be interested, I said no, then hung up the phone.
