FAQ's

How long does installation take?

How long does installation take?

Installation typically takes about 4-6 hrs, depending on the size and complexity of the system. Our technicians will ensure everything is set up properly, tested, and ready to go before they leave.

Is it easy to expand the system later?

Is it easy to expand the system later?

Yes, our systems are designed to grow with your needs. You can add extra devices, such as cameras, motion sensors, or smart home features, at any time. Everything integrates seamlessly with the existing setup.

Can I transfer the system if I move?

Can I transfer the system if I move?

Yes, the system can be transferred to your new home. We’ll work with you to uninstall and reinstall the system so it’s ready to protect your new property.

Why does buying local make such a difference?

Local Focus vs. National Brands 

Because when you call, you reach a real person — right here in Sioux Falls. No call centers, no transfers, no “press 4 for support.” We design, install, and service every system ourselves, so we actually know your setup and your neighborhood. We’ve built our reputation on doing right by our neighbors for over 20 years — not chasing national quotas.

Aren’t DIY systems cheaper?

Aren’t DIY systems cheaper?

Up front, maybe. But here’s the catch — DIY systems rely on you for setup, troubleshooting, and maintenance. One loose wire or missed update, and you’re on your own. FOSS systems are professionally installed, optimized for your exact home or business, and supported for the long haul. You’re not just paying for equipment — you’re paying for reliability, real expertise, and peace of mind that lasts.

What’s the biggest reason people switch to FOSS?

Why your neighbors choose Foss

It’s simple — service. When something happens, you want to call someone who answers, shows up, and fixes it. That’s been our promise for two decades, and it’s why hundreds of Sioux Falls families and businesses have trusted FOSS over big-box or DIY setups.
