Common Home Security Mistakes and How to Avoid Them

-Matson Alarm of Tennessee-

Keeping your home safe should never be an afterthought, but you’d be surprised how many people leave themselves vulnerable without even realizing it. At Matson Alarm of Tennessee, we’ve seen the same security slip-ups over and over again, and unfortunately, they can lead to costly or even dangerous consequences.

If you’re looking to protect your loved ones and your property, this blog is your blueprint for better home security. We’ll walk through the most common mistakes homeowners make and give you actionable ways to avoid them.

1. Forgetting to Lock Doors and Windows

It might sound too obvious, but an unlocked door or window is still one of the top ways burglars gain entry. Many break-ins are crimes of opportunity, so if your back patio door is unlocked, you’re essentially inviting trouble.

How to Avoid It:

  • Double-check all entry points before leaving or going to bed
  • Install smart locks that you can control and monitor remotely
  • Consider door and window sensors for real-time alerts

2. Relying on Just One Layer of Security

A basic alarm system is a great start, but relying solely on it is like locking your front door but leaving your windows wide open. Security should be layered.

How to Avoid It:

  • Combine alarm systems with cameras, lighting, and sensors
  • Reinforce doors and install deadbolts
  • Use smart home integration to create a responsive ecosystem

3. Poor Placement of Security Cameras

Installing cameras but pointing them at the wrong angle, or too high up to capture faces, is a common mistake. Visibility is everything when it comes to catching details.

How to Avoid It:

  • Position cameras at eye level for facial recognition
  • Focus on high-traffic areas: front door, back door, driveway
  • Test angles and lighting before finalizing placement

4. Ignoring Your Garage

Your garage may seem less important than your front door, but it’s often a prime target, especially if it’s connected to your home or contains expensive tools and vehicles.

How to Avoid It:

  • Install sensors and cameras in and around the garage
  • Never leave garage doors open or unlocked
  • Use smart garage door openers for added control

5. Not Updating Emergency Contact Information

You’d be amazed how often outdated contact information delays emergency responses. If an alarm goes off and the monitoring center can’t reach you or your contacts, precious time is lost.

How to Avoid It:

  • Regularly review and update your contact list with your alarm provider
  • Include multiple reliable contacts
  • Make sure all parties know how to respond in case of alerts

6. Overlooking Outdoor Lighting

Dark corners are a burglar’s best friend. Poor lighting can turn your yard into a hiding spot and make your home look unoccupied.

How to Avoid It:

  • Install motion-activated lights around entryways and driveways
  • Use timers or smart lighting to mimic activity
  • Illuminate all points of entry, including side gates and backyards

7. DIY Installation Without Professional Help

DIY security systems are appealing, but improper installation can leave gaps. Worse, many homeowners think they’re protected, until something goes wrong.

How to Avoid It:

  • Trust professional installation from a licensed provider like Matson Alarm of Tennessee
  • Get a custom assessment of your home’s vulnerabilities
  • Ensure your system is tested and maintained

8. Not Using Alarm System Features

It’s one thing to install a system, it’s another to use it effectively. Many homeowners disable features or forget to arm the system altogether.

How to Avoid It:

  • Set reminders to arm your system
  • Take advantage of mobile apps for remote control
  • Automate routines like arming at bedtime or when leaving home

9. Leaving Spare Keys in Obvious Places

Under the doormat, inside the flowerpot, behind the mailbox, you name it, burglars know where to look. A spare key outside might as well be a welcome sign.

How to Avoid It:

  • Use a secure smart lock with access codes
  • Give a spare key to a trusted neighbor instead
  • If you must use a lockbox, choose a well-hidden and tamper-proof one

10. Ignoring Software Updates on Smart Devices

Smart home devices like cameras, locks, and thermostats can have vulnerabilities, especially if not updated. An old firmware version could be a hacker’s open door.

How to Avoid It:

  • Regularly check for and install updates
  • Change default passwords and use strong credentials
  • Use encrypted connections and multi-factor authentication when available
