The system is good, but do not expect them to work with you on service calls. They do not do anything after 5 pm and no weekends, so you have to take time off of work to meet a technician at your house. Also the technician showed up and told me the glass break detector that was installed was not covering the area they said it did. When asked if he would install another one to cover the area, I was told it would be $120 to get another one. So the person that installed the system did not tell me the truth on the coverage.
