We installed our alarm system with TMC (The Monitoring Center) after we heard their radio ad on 1130 AM. The price was affordable (9.99/mo plus 6 months for free), plus the one-time installation ($99) and equipment fees ($299 for two doors & one sensor). We ended up installing more door alarms and sensors. The tehnician (Adam) was very professional & knowledgeable. So far the service is going great and we love the peace of mind it gives us.
