Top 7 Security Mistakes Homeowners Make (And How to Fix Them)

When it comes to protecting your home and family, even small oversights can create big vulnerabilities. At Advanced Alarm, we’ve seen it all—and we’re here to help you avoid the most common home security mistakes homeowners make.

If you're ready to tighten up your defenses and enjoy greater peace of mind, start with these seven mistakes—and how to fix them fast.

1. Forgetting to Arm the System

It sounds obvious, but one of the most common security slip-ups is simply forgetting to arm your system when you leave the house.

The Fix:

Choose a system with reminders, automation, or remote access so you can arm your alarm from your phone—no matter where you are. Many modern systems, including ours, can even send a push notification when the system is left unarmed.

2. Leaving Valuables in Plain Sight

Burglars often “shop” from the street. If high-ticket items like TVs, laptops, jewelry, or tools are visible through windows, your home may become a target.

The Fix:

Close blinds or curtains when you're away. Consider frosted window film in areas where privacy is important but natural light is still needed.

3. Neglecting to Lock Windows and Secondary Doors

First-floor windows, garage doors, and even basement entrances are frequent entry points for intruders. These are often left unlocked—especially in nice weather.

The Fix:

Add door and window sensors to every potential entry point, not just the front door. It’s also smart to integrate them with your alarm system so you’re notified of unusual activity right away.

4. Skipping Security System Upgrades

Technology evolves quickly. Older systems may lack features like mobile access, real-time alerts, or HD video surveillance.

The Fix:

Schedule a free security assessment to evaluate your current setup. Even a basic upgrade to a smart alarm panel or camera system can make a big difference.

5. Poor Exterior Lighting

Dark entryways, backyards, and driveways give intruders cover. A lack of lighting makes it easier for someone to approach undetected.

The Fix:

Install motion-activated lights around doors and pathways. Bonus: this also helps deter wildlife and keeps guests safer at night.

6. Posting Travel Plans on Social Media

Broadcasting your vacation can inadvertently invite break-ins, especially if your address is easy to find online.

The Fix:

Wait until you’re home to share photos or stories. Ask a trusted neighbor to grab mail and keep an eye on things while you're away.

7. Relying Only on DIY Solutions

DIY systems may offer convenience, but they often lack professional monitoring, robust support, and local expertise in evaluating real threats.

The Fix:

Work with a trusted local provider (like Advanced Alarm!) to get a system that’s professionally installed, monitored 24/7, and customized for your home.

Bonus Tip: Schedule a Local Security Review

Every home is different—and so are the risks. Whether you’re a new homeowner or have lived in your house for decades, a fresh set of eyes can help spot vulnerabilities you didn’t know existed.
