Foss Security

Foss Security At FOSS, our commitment to excellence shapes every aspect of our interaction with you.

We pride ourselves on delivering not just high-quality products and services, but also ensuring they align perfectly with your needs and expectations. Foss got its start in 1998 providing primarily voice/data cabling services for the commercial market. In 2000-2002 it expanded its offerings to add security services, small telephone systems, and central vacuum systems. Foss now provides a full line

of services for both the commercial, residential, and agricultural markets. We are unique in that Foss & AVI both specialize in their respective fields, but work together with a combined office and Custom Design Center to provide you a central point of contact with a full menu of services. We are able to provide our clients the specialized expertise they expect from multiple companies while eliminating the hassle and confusion of using multiple contractors.

"We found cameras cheaper online. Can you install them?"
We hear this question a lot.

We supply, install, train, and support every system we sell. That's how we can stand behind it for years to come.

Before comparing prices, compare what's included.

Who Answers When Something Stops Working?
Security systems aren't just products. They're ongoing services.

Ask:

• Are technicians employees or subcontractors?
• Is retraining available years later?
• Is someone available after installation?

Not All Security Systems Are Created Equal.
Two quotes can look similar on paper and perform very differently in your home.

One camera may capture 4 megapixels while another captures 8 megapixels. Both are called "security cameras," but they don't provide the same level of detail.

Before comparing prices, ask:
• Camera resolution
• Night vision performance
• Recording retention
• Smart analytics included
