So let's review. Your basic home security systems typically include your keypad, 2 door sensors (front & rear) and 1 motion detector. As I said this is usually consistent with the top companies as ADT and Protect America. Your pricing for a basic system should start around $35/month for monthly monitoring. Which isn't bad considering your family and valuable are priceless. I'd suggest you call ADT (877) 631-9346 & Protect America (877) 634-5597. To discuss your home security needs.
