Our technician group averages 10 years security system experience.  Our sales core offers expert advice to help you design, install and monitor security systems in your home and business, securely protecting Life, Safety & Property. We operate our own Central Station Monitoring Center in White Bear Lake which helped us earn an "A" Rating by the Better Business Bureau. (April 22, 2010 www.bbb.org) This local operation of our Central Station gives us great local ties with Law Enforcement. Isn't an "A" rating from the BBB what you would expect from your security company? After more than 45 years of service it is what we expect from ourselves. How does your security company rate?
