With over 50 years of staff experience we confidently proclaim to be "New England's Premier Alarm Company". While many companies use "slick" company mission statements and mottos, Sentry lives out its mission every day by action not simply words. What consumers find most interesting about Sentry is our cutting edge technology. As I am sure you noticed on our web site, we really emphasized Sentry Total Connect. This is really awesome as our clients have security and convenience right at their fingertips (smart phone, computer, etc). Consumers want the best (and also deserve the best) and Sentry has again lived up to being New England's Premier Alarm Company. Our Mission: Sentry promises to provide the best possible residential and commercial alarm security products and services available for our clients at affordable and fair rates, be available 24/7 to our clients and we promise to follow the sunset rule which means all calls are returned before the sun sets.
