We have a system that we had installed by another company a few years ago. After 3 years of paying $40 a month (after about $600) upfront), I stopped the service for more than a year. I was looking for a company that could work with the system that we had, fix anything that wasn't working and monitor for a more reasonable monthly price. Protection Concepts told me that really all I needed was new batteries and a couple new door sensors and that was it. It all ended up costing less than I thought it would and works great. So far so good.
