These guys are great. You can't go wrong with the services they provide. We were broken into in October 2013 and finally decided to get home security. We looked at other companies and honestly came pretty close to signing up with national companies like ADT. I looked one more time and found these guys. I think their youtube video convinced me more than anything.
I called them up and they came by the next day to get things going. If anything it gives you a peace of mind. The sensors accidentally detect when, say, a glass pan breaks so that should tell you how sensitive they are. Customer service is great. Compared to other companies they really are a huge deal for what you get.
