When it comes to securing your home, some of the smartest solutions are also the simplest. Entry sensors—small, discreet devices placed on doors and windows—are one of the most effective ways to protect the people and places you love. Whether you live in an apartment, townhome, or large family residence, these sensors instantly alert you to unwanted activity, giving you confidence that your home is always protected.
At Crime Prevention Security Systems, we’ve been helping Florida homeowners feel safer for over 50 years. Entry sensors are one of the foundations of our smart home security systems—and one of the most trusted tools our customers rely on every day.
Read on to learn how CPSS Entry Sensors work, why they’re essential, and how to choose the right ones for your home.
What Are Entry Sensors—and How Do They Work?
Entry sensors are designed to detect unauthorized opening or tampering of doors and windows. When a protected entry point is disturbed, the sensor communicates with your CPSS smart home system, triggering an alarm and sending real-time alerts to your phone and to our 24/7 monitoring center.
Every entry sensor has two main components:
1. Sensor (Mounted on the Frame)
This piece contains a magnet and a reed switch. When the door or window is closed, the magnet holds the reed switch in place, completing an electrical circuit. This means the entry point is secure.
2. Magnet (Mounted on the Door or Window)
As soon as the door or window opens, the magnet separates from the sensor. This breaks the circuit, triggering an alert and activating your alarm system.
From there, the CPSS Smart Home App sends an instant notification to your phone letting you know exactly which entry point was opened. If you have professional monitoring, our trained operators take immediate action—verifying the alarm and dispatching authorities if needed.
Fast. Connected. Secure.
That’s the CPSS difference.
Why Entry Sensors Are a Must-Have
With so many security devices available today, it’s easy to wonder where to start. Entry sensors offer several major benefits that make them one of the smartest—and most cost-effective—investments you can make:
✔ Strong Visual Deterrence
A would-be intruder who sees security sensors—or even knows a home has a monitored system—is more likely to move on.
✔ Real-Time Alerts Anywhere You Go
With the CPSS Smart Home App, you stay informed from anywhere in the country. If a door or window is accessed, you’ll know immediately.
✔ Seamless Integration
Entry sensors work perfectly with your CPSS smart security system, connecting to cameras, smart locks, alarms, and our 24/7 monitoring team.
✔ Budget-Friendly Protection
Entry sensors add powerful security without a large cost, making them perfect for families building their first system or upgrading an existing one.
✔ Customizable Setup
Protect exterior doors, sliding glass doors, windows, storage rooms, garages, home offices, or any interior doors you want monitored.
How to Choose the Right Entry Sensors
When you’re comparing options, consider the following:
Assess Your Home’s Needs
Count the doors and windows you want to protect. Think about sliding doors, basement entrances, or any overlooked access points.
Check Smart Compatibility
Your sensors should work seamlessly with your full smart home system—especially if you’re using the CPSS app, smart locks, or connected cameras.
Compare Features & Value
Not all sensors are built the same. Make sure you understand the range, battery life, app features, and warranty.
Read Reviews & Ask Neighbors
Local opinions matter. Your neighbors may already be CPSS customers—ask what’s working for them in their homes.
Consider Installation Preferences
CPSS offers professional installation, so your sensors are placed correctly, calibrated properly, and integrated with your system from day one.
Maintenance Tips
- Check regularly: Ensure sensors remain tightly mounted and free of dust.
- Replace batteries as needed: Most sensors will alert you when battery levels are low.
- Perform routine tests: Open each protected door or window to verify the system is responding.
The Bottom Line
Entry sensors may be small, but they play a huge role in protecting your home. They’re affordable, reliable, and essential for anyone who wants round-the-clock security and peace of mind.
Whether you start with a few sensors or add them to a full CPSS smart home package, they provide the confidence of knowing your home is protected—when you’re away, when you’re asleep, and when your kids are home alone.
For professional installation, smart home integration, and 24/7 monitoring you can trust for life, Crime Prevention Security Systems has you covered.
