In the world of security systems, there is no room for compromise—especially when the safety of people, data, and infrastructure is at stake. The GRADE classification system allows for precise determination of the level of protection required for a given facility. The highest level—**GRADE 4**—is intended for the most demanding and strategically important environments, such as military facilities, government administration, research laboratories, or critical infrastructure.

At **Roger**, we not only understand these needs—we deliver solutions that meet them effectively.
