5 Ways To Check for Gaps in a Residential Security System
Leave No Loopholes In Your System

A strong security system protects your home, belongings, and loved ones, but only if it works as intended. Over time, small weaknesses can appear, leaving vulnerabilities that intruders could exploit. Knowing how to evaluate your home’s protection is essential for peace of mind. Here are five ways to check for gaps in a residential security system and keep it working at its best.
1. Review Camera Coverage and Blind Spots
Inspect every camera’s field of view for blind spots. In addition, walk around your property and observe the areas each camera records. Pay special attention to entry points, such as doors, windows, and garage access.
If your system lacks coverage in any of these areas, reposition existing cameras or add new ones. Hiring an expert for professional security camera installation can guarantee optimal placement for full perimeter monitoring.
2. Test Door and Window Sensors Regularly
Door and window sensors provide the first alert if someone tries to enter your home. Over time, these sensors can shift out of alignment or lose battery power. Open and close the door or window that each sensor monitors while the system stays armed. If the alarm does not trigger, replace the batteries, recalibrate the sensor, or upgrade to a more reliable model.
3. Evaluate Motion Detector Range and Sensitivity
Motion detectors play a critical role in catching movement inside and outside your home. Test each detector by walking through its coverage area to see if it triggers the alarm. If the detector fails to detect movement or reacts too slowly, adjust its angle, height, or sensitivity settings. In some cases, replacing outdated detectors can improve response time and accuracy.
4. Check Alarm Connectivity and Alerts
Even the most advanced system loses value if it fails to send alerts when triggered. Test your system’s connection to monitoring services, mobile apps, and backup communication methods. Confirm that text, call, or email alerts arrive quickly and consistently. If delays occur, consult your provider or upgrade your network to support faster transmission.
5. Inspect Physical Barriers Around the Property
Your security system works best when paired with strong physical barriers.
- Inspect locks, deadbolts, and reinforced strike plates on all doors.
- Evaluate window locks and security film for added protection.
- Trim landscaping that could conceal someone approaching your home.
- Check that fences or gates close securely without gaps.
By following these five ways to check for gaps in a residential security system, homeowners can ensure their safety measures remain effective. Regular maintenance and occasional upgrades from Action Security Group will protect your investment and keep your home secure.
