Didn't answer. No message. Caller ID shows NATIONWIDESECUR

A call from this number and then 2 minutes later a call from SECURECARETEC. Coincidence?

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.
