We had Scott security monitoring our Condo for 3 years from 2007-2010, so when we moved to a house in 2010 we decided to keep Scott Security. They were really good at ensuring everything was done in a timely manner. Our windows and doors were already pre-wired for an Alarm system, so it made their job a little easier but still everything was done rather quickly.
The only thing i have an issue with is their lack of technological advances such as the video monitoring over internet/cellphones since other companies are now offering those systems at comparable or lower monthly costs than what I'm paying now ($30/month). I feel for $360 annually I should be getting more than just a monitoring from a central dispatch. Other companies are offering simple alarm monitoring for far less money.
Nevertheless Scott Security was always good at being able to upgrade my panels and to accommodate my needs.
