Must I buy whole New Security System
Greetings and thanks in advance for all advice. Had a home security system installed years ago from a local contractor, through whom I also contracted monitoring and service contract. He went out of business, and at the same time, I've made some changes (changed windows, etc) that requires some update to the programming. calling around to local companies, the general thread is that they want to install a whole new system. Before I call everyone in the yellow pages, is it unreasonable to be thinking that I can find another local company to put a service/monitoring contract on this existing system?
