Scammers are going door to door and selling you something you think keeps your family safe.
But they are really just taking your money and keeping you vulnerable to thieves.
There's been a steady increase in scams wandering through you're neighborhood lately.
"We've seen an increase in door to door sales from companies... door to door sales across the board. Particularly this summer and fall with security companies," said Janna Kiehl with the Better Business Bureau.
Experts say the companies come in and set up equipment but from the start it's illegal.
"His company wasn't licensed, he wasn't licensed, his technician wasn't licensed. So they shouldn't be able to operate in the state of Texas but they are... Illegally," said Eric Norman, the owner and president of Central On-Line Security.
The state of Texas regulates the private security industry. Everyone involved with a security company is required to be licensed and have a background check performed by the FBI.
But many of these door to door sales companies aren't regulated at all.
Norman and Kiehl say there are a few things you can do to protect yourself.
First off, check any door to door salesman for their license from the city of Amarillo, then....
"Get references, get five or 10 of them and call. Check them out," said Norman.
"A buyer wants to check out with the Better Business Bureau before they sign anything and before they pay anything. This way they know who they're dealing with and the company is going to give them what's promised,"Kiehl said.
