The Good

Customization
Easy To Upgrade
Excellent Customer Service
Takeover Existing Equipment
Flexible Payment Options

Unlike traditional security companies who offer standard equipment packages, Sentry Protective Services prides itself on designing custom systems to meet customer needs. Sentry designs burglar alarm systems with additional services such as fire alarm, video surveillance, and its home automation service, Sentry Total Connect. One added benefit of going with Sentry Protective Services is that it recognizes that your needs change over the years. If you purchase a basic security system, you can upgrade and enhance your system at any time. Sentry says that over 90% of its customer base comes from referrals alone. Rather than spending money on advertising, the company prefers to focus on improving its customers' experience. From online reviews, this sentiment is backed by many positive customer reviews regarding Sentry's professionalism and excellent customer service. This is also evident in that its customer service phone line is available 24 hours a day, 7 days a week. If you currently have a security system with a different company, Sentry has the ability to take over your current system and provide 24/7 monitoring. Sentry also provides flexible payment options such as discounts for yearly services.

The Bad

Poor Online Transparency
Small Service Area
Non-Proprietary Equipment

Sentry's website does not include any pricing details for upfront costs, equipment fees, or monthly monitoring plans. While this is not included, because each system is catered to individual customer needs, this adds an extra step in your security system search. A free consultation is necessary to evaluate your home or business and then design a system from there. Sentry Protective Services also services a limited area, specifically Boston, Massachusetts, Southern New Hampshire, and surrounding areas. While it is likely that you'll hear about Sentry Protective Services from a friend or neighbor, if you are investigating New England security companies, call to ensure that your home or business is in the service area. This is also a potential issue if you decide to move outside the area prior to finishing your contract with Sentry. Another downside to going with Sentry is that it doesn't own or make its equipment offerings. It sells Honeywell equipment to its customers, which, while used by many security providers, it sometimes can cause problems if your system experiences an equipment issue beyond the company's control.

The Bottom Line

If you are in the Boston, Massachusetts or Southern New Hampshire area and are seeking a custom security company, then Sentry Protective Services should meet your needs. However, if you're looking for standard equipment packages and pricing and may move out of the New England area in the future, we recommend looking at other options.
