Don’t be fooled by “free alarm system” scams

Because we value honesty and transparency, we will never rope you into a “free” alarm system scam. In truth, “free” alarm systems are really nothing more than a way to get you to pay for the equipment cost in your 3-5 year contract. What this means is that even after you pay off the “free” alarm within the first year, you will be stuck paying an astronomical monthly rate for the next 2-4 years. And what happens if you are unhappy with the level of service this company is providing you? Unfortunately, you will have to stick it out with the company until the end of your contract.
