Call us at 617-532-1013. You'll be pleasantly surprised. With over 50 years of staff experience we confidently proclaim to be "New England's Premier Alarm Company".

Not all home security systems are created equally! You've probably seen the slick ads offering a free residential security system or some sleek package deal. Like you, we know you get nothing for free. There is always a catch. At Sentry we take your family's security and safety seriously and we provide a professional and courteous approach in designing a home security alarm system that fits you and your family's needs.
At Sentry we work with each of our small and medium sized business clients to customize a security alarm systems that best fits the situation. For example, with our state of the art alarm technology, we can integrate burglary protection with video cameras and surveillance. In the event of a burglary the client would get an email video clip in addition to the central station dispatching the authorities.
With Sentry Total Connect Remote Video Surveillance Monitoring Services, you can stay connected and in control of your home or business whenever you want, wherever you are through a mobile solutions. Control your security alarm system, receive important alerts and true system status in real-time through our remote surveillance equipment.
Are all security video camera and CCTV camera systems the same? Of course not. If you want to really see the difference then have Sentry come out and visit with you so we can show you with our live interactive presentation. We will show you actual operating camera and CCTV video systems with permission from some of our clients.
A professionally installed burglar intruder alarm system by Sentry includes many benefits to homeowners and businesses. Each Sentry burglar alarm system is custom design to tailor your needs not a "one size fits all" like 2 doors and a motion sensor advertised by many national alarm security companies.
