Northwestern Ohio Security Systems, Inc. (aka NWOSS) was established in Lima, Ohio in 1981 by brothers-in-law Trell Yocum and Jim Kostelac, a U.S. Army Veteran. NWOSS is a regionally renowned and award-winning security integrator. Seeing a need to provide its customers with professional, local monitoring services, NWOSS also established its own Monitoring Station in Lima, Ohio.

NWOSS has mainly catered to commercial clients–businesses, government agencies, factories, schools, hospitals, and more. To protect their own homes and families, Jim and Trell wanted these same commercial-grade systems for themselves. 

Safety, security, protection. Those three words mean a lot to us. At NWOSS, we believe everyone deserves to feel safe in their environment. Our team is here for you. We’re local and we’re passionate about what we do. With us, you aren’t getting a device that watches you. You’re getting a safety net. You’re getting a team that cares about your security.
