Recent Review: We found Millennium Alarm on Angie's, but looked at several others before deciding. Pricing was reasonable, and the contractor and support staff were knowledgeable and answered questions and made suggestions that made sense for our system. The contractor was punctual, cleaned up after himself, and spent an appropriate amount of time explaining the Do's and Don'ts of our system. When we accidentally turned off the power at the breaker the next day, we got a phone call, as expected... Overall, a great experience!
