Caller left a almost impossible message to understand......very broken English....about purchasing an affordable security system for my home in "America"..........does anyone else think that is odd?

I received a call from this number 5 minutes ago, it was from New Jersey, i didn't answer. I rarely get calls from scammers, or solicitors but i have gotten 4 from different numbers in the last 2 days. I'm wondering if they are connected.
