Did you manage to fix the issues with the cameras?
I have a cellular based system from Frontpoint security that we've had for 7 years but I was thinking of switching, maybe to something like SS, and also include cameras.
BTW, I recently took the "Unthinkable" class from William Aprill, and the story he told about the small alarm company owner psychopath that would rob his customers eventually, and ended up skinning one of his victims that he found sleeping on his couch when he went to rob his home has definitely validated the concept of installing your own system through a vetted company! I know I know, not likely to happen, but still!
