There are a lot of “free” home security systems being advertised in Prosper, don’t fall into the trap!

A lot of other security companies and many newer startups try to bait new customers in with an attractive “free” alarm system that turns out to be anything but. What they don’t realize is that once you’ve signed the contract the exorbitant cost of the alarm equipment is often folded into the monthly payments. This not only means that they are actually paying for the alarm system, but it also leads to higher monthly payments. The worst part is that since they signed a contract to take part in the initial “free” alarm system promotion, they are stuck with that company and cannot simply take their business somewhere else.
