EMC Security is very slow at responding when the alarm goes off. I have accidentally set off my alarm a few times and each time it has taken them almost two minutes to call me. If it were a real accident, anything could have happened by the time they finally decided to call. I have been a customer for over a year now, but I will be switching to a different monitoring service next month. It makes no sense having a security monitoring service that isn't prompt on emergency alarms.
