🚨 SIMPLISAFE VS. PROFESSIONAL SECURITY — THERE’S A BIG DIFFERENCE! 🚨

Just because you can buy an alarm system in a box doesn’t mean you’re getting professional protection!

Let’s get something straight. There’s a HUGE difference between sticking a few wireless sensors around your house and having a security system professionally designed, installed, and serviced by people who actually know the industry.

Companies like SimpliSafe have convinced consumers that security is as simple as opening a box, downloading an app, and sticking sensors on doors.

Here’s the problem: SECURITY ISN’T ONE-SIZE-FITS-ALL!

❌ DIY INSTALLATION: Who’s determining the proper placement of your devices? Who’s identifying vulnerable areas you might overlook? You are. And unless you’re trained in security, you may not even know what you’re missing.

❌ FALSE SENSE OF SECURITY: Just because your phone says your system is armed doesn’t automatically mean your entire property is adequately protected.

❌ LIMITED PERSONALIZATION: A prepackaged DIY system can’t replace an experienced professional walking your property, identifying weaknesses, and designing protection around your actual needs.

❌ WHO’S COMING TO FIX IT? When something isn’t working correctly, do you want to troubleshoot it yourself, deal with remote customer support, or call a local company that knows your installation?

❌ CHEAP UPFRONT DOESN’T ALWAYS MEAN BETTER VALUE: Before choosing a DIY system based on price, compare the equipment, monitoring features, ongoing costs, service, and long-term support.

🔥 HERE’S WHAT OVER 50 YEARS IN THE SECURITY BUSINESS HAS TAUGHT US:

ANYONE CAN SELL YOU AN ALARM. NOT EVERYONE KNOWS HOW TO PROPERLY PROTECT YOUR PROPERTY.

At Nationwide Alarm Company Inc., we’ve been family owned and operated since 1970.

We’ve spent decades installing, servicing, troubleshooting, and designing security systems for homes and businesses.

We don’t just hand you a box and wish you luck.

✔️ We evaluate your property.

✔️ We identify potential security vulnerabilities.

✔️ We professionally design and install your system.

✔️ We stand behind our installations.

✔️ We provide real experience, professional service, and local accountability.

We’re not competing to be the cheapest alarm in a cardboard box. We’re competing to provide professional security backed by decades of experience.

💥 YOUR FAMILY ISN’T DIY. YOUR BUSINESS ISN’T DIY. WHY SHOULD YOUR SECURITY BE?

If all you’re looking for is the cheapest alarm you can stick on a wall, there are plenty of options.

If you’re looking for experience, professionalism, and a company that stands behind its work, give us a call.
