We have been with Sentry Security for over 5 years. Their management, office staff, and technicians have always been professional and helpful. One of the things I like is that when I call them a person always answers the phone, I never receive a recording and this is extremely important to me at the times that I need to speak with someone. Their employees are always willing to take the extra step to make sure that our security needs are addressed. Whenever we have a technician working at any of our branches they perform their duties as if this system was their own. I am very pleased with the service and support that we receive from Sentry Security and would never think of placing our security needs in any other company’s hands.Chicago-Focused Federal Credit Union

We have been using the services of Sentry Security for over 12 years for all of our projects and security hardware/software needs. We are in a continuous state of construction and the coordination with Sentry and our Architects are seamless. Once we make the decision on security devices (card readers, cameras, intercoms, panics) to be installed in a construction project, Sentry is able to see it thru to completion without issue. They have a very knowledgeable staff and have been a great partner.Chicago-Wide Hospital Network, Security Director

Sentry Security recently planned and installed a comprehensive security system throughout our new construction office building. The sales team proposed simple, cost-effective solutions that went above our expectations for security. Our installation coordination thoroughly communicated to use throughout the installation and even provided hands-on trainings for all systems and web interfaces. Sentry responds quickly to every customer service call and the office team makes sure there is an answer the very same day. We are very pleased with Sentry and will always work with them in the future.Chicago-based Natural Gas Producer
