Don’t be fooled by Katy home security companies that offer “free” alarm systems

Unfortunately, home security companies that offer you an alarm system for “free” are really just playing a trick on you. In fact, the higher monthly monitoring rate you will be paying will also be paying for that “free” alarm system and more. On top of that, the company will require you to sign a contract with them, keeping you paying those massive fees for 3-5 years, even after the cost of the “free” alarm system is completely paid off. And what if you are unhappy with the company’s quality of service? Too bad. You’ll be stuck with them until your contract is over.
