Granite Security Gaithersburg, MD

Our company was established in 1995 by former United States Government security specialists providing advanced and unique security systems designs for the protection of classified assets, facilities and personnel entities within the Intelligence Community, Department of Defense, and Diplomatic Missions world-wide. Today, in addition to United States Government clients, we deliver this same level of elite electronic physical and technical security know-how to commercial, industrial and high-profile VIP residential clients.

Specific areas of expertise include facility & perimeter intrusion detection, facility & perimeter access controls, as well as digital video surveillance recording and storage solutions. Also, when a client possesses an in-house installation resource, we can augment this capability with skilled consulting assistance by way of security technology research and source selection support. At Granite Security Inc., just meeting the customer's stated requirements has been never enough. Our bench mark is ensuring that a project is approached and executed from a complete life-cycle perspective to ensure maximum return on investment over an extended period.

Products and Services
We are committed to delivering advanced solutions using cutting edge technologies. From digital networked video to recorders to the rapidly advancing IP-Cameras, we will tailor the appropriate system or technology for you. For clients that have needs for the enhancements provided by newer digital technologies, but have sizable investments in their legacy analog CCTV systems, and therefore not yet ready to upgrade, we offer hybrid products that allow them to leverage their existing analog cabling infrastructures while establishing a cost effective migration path to the digital age.

From Government and industrial facilities to educational, medical and multi-tenant complex environments, GSI offers scalable, enterprise-class Access Control & Management solutions that seamlessly integrate with security and building management infrastructure.
