Door and Window Security sensors

Advanced Door & Window Contact Sensor Installation in South Florida

The absolute foundation of an unbreachable home security network starts at your physical entry points. If your primary doors and window tracks are left unmonitored, your entire interior is left completely exposed to rapid forced entry. Standard stick-on consumer retail contacts fall short, relying on weak, unencrypted wireless signals that are easily jammed, dropping off their networks, and using bulky plastic frames that ruin your home’s aesthetics. At Protect Pros LLC, we secure South Florida home perimeters by installing professional Door and Window Contact Sensors featuring Encrypted Two-Way Wireless Technology.
As an Authorized ADT Dealer and licensed Florida low-voltage electrical contractor (#EF20002132), we do not deploy loose, unmonitored retail gadgets. Our field technicians professionally mount and align ultra-low-profile magnetic contact arrays that integrate natively with your central ADT Command platform. Operating with continuous bidirectional health supervision and backed by 24/7 professional ADT monitoring, our contact lines lock down your structural perimeter the exact millisecond a frame is compromised.

Door & Window Contacts At a Glance

Ultra-Low-Profile Magnetic Gap Matrix: Sleek, high-flux reed switches engineered to fit seamlessly within standard door frames, impact window tracks, and sliding glass rails.
Encrypted SiX™ Two-Way Communication: Continuous bidirectional cryptographic validation utilizing military-grade 128-bit AES encryption to completely block signal jamming.
Continuous Battery and Supervision Logs: Around-the-clock panel health checks that monitor sensor connectivity, battery levels, and physical cover status every single hour.
Immediate Local Siren Activation: Sub-second signal transit times that trigger high-decibel property sirens the exact instant a secured perimeter line is broken.

Hardening Structural Entry Points with Advanced Magnetic Reed Switches

Traditional mechanical switches rely on moving parts that easily rust, stick, and fail over time—especially under the stress of South Florida’s high coastal humidity and salt-air exposure. Our premium contact sensors completely eliminate these mechanical failure points by utilizing advanced Solid-State Magnetic Reed Switches.
The sensor assembly consists of two micro-components: an internal magnetic reed switch mounted to the stationary door or window frame, and a companion high-flux magnet attached directly to the moving sash or door panel. When the door or window is sealed tight, the magnetic field holds the internal switch contacts in a secure, closed state. The exact millisecond that frame moves even half an inch apart, the magnetic field breaks, instantly severing the circuit and signaling a perimeter exception to the central processor.
Our hardware is uniquely engineered inside ultra-thin, sleek structural housings. This allows our technicians to mount the sensors flush along your expensive impact windows, French doors, and heavy horizontal sliding tracks without interfering with your home’s architectural aesthetics or blocking your window blinds.

Perimeter Tracking in Action: Real-World Entry Point Protection

Door and window contact sensors serve as your property’s immediate line of physical defense. By combining solid-state magnetic reed switches with secure remote app logging, your contact network actively tracks entryway integrity. Here is exactly how your contact sensors perform in real-world situations:

The Situation: A burglar attempts to pry open a locked side window or patio door at 2:00 AM while your system is armed in “Stay” mode, forcing the window sash upward.
The Sensor Response: The exact millisecond the frame shifts even half an inch, the internal magnetic field breaks. The contact sensor bypasses all entry countdown delays to instantly transmit an encrypted packet to the ADT Command panel. The central panel instantly activates your high-decibel interior and exterior sirens, waking your family and routing a priority dispatch signal to ADT monitoring centers within a sub-second window.

The Situation: A violent South Florida summer storm drops intense wind gusts directly against your heavy front entry door, causing the wooden door frame to shake and rattle violently inside its tracks.
The Sensor Response: While cheap consumer sensors with sloppy tolerances would trigger a frustrating false alarm from the physical shaking, our advanced hardware handles it smoothly. The high-flux magnetic field features a highly precise operational gap tolerance, allowing for natural structural movement and heavy wind vibration while remaining fully secure unless the door frame is completely separated.

The Situation: An intruder walks up to your rear French doors while the home is completely empty and armed in “Away” mode during the workday, using a tool to smash the lock and swing the door open.
The Sensor Response: The moment the door leaves the frame, the solid-state magnetic switch opens. The sensor launches an immediate alarm loop, firing the property sirens to scare off the intruder. Simultaneously, the system pushes a high-priority “Zone Intrusion Alert” straight to your smartphone app dashboard, giving you instant situational awareness.

The Situation: Your children arrive home from school in the afternoon and open the main garage entry door to step inside while you are away at work.
The Sensor Response: The moment the contact switch separates, it logs the entry event. Because the contact is tied to a standard entry delay zone, it gives them 30 seconds to type their custom code into the touchscreen panel. The event is instantly mirrored to your smartphone app timeline, showing you the exact second the garage door opened so you can easily verify they made it home safely.

The Situation: You are leaving the house in a rush for an afternoon errand and attempt to arm your system to “Away” mode via the central panel, completely unaware that a guest left a rear bedroom window open.
The Sensor Response: Rather than arming blindly and leaving your home vulnerable, the ADT Command panel scans the perimeter and notes that the specific bedroom window contact is in an open state. The panel immediately chirps to deny the arming sequence, displaying the exact room coordinates on the touchscreen. This forces you to close the open window and seal the perimeter before leaving the property coordinates.

The Situation: A severe tropical weather system drops a lightning bolt onto your neighborhood utility lines, completely knocking out your home’s main electrical grid, internet router, and Wi-Fi network.

The Sensor Response: Your physical boundary lines remain 100% alert and fully monitored. Every door and window contact is powered by completely independent, internal long-life lithium battery cells located securely inside the frame housing. Because the sensors do not pull power from your home’s electrical grid or rely on your Wi-Fi network to pass signals, they continue to monitor your perimeter flawlessly, routing emergency data over your panel’s cellular backup radio during a complete blackout.

Home security perimeter protection sensors

Uninterrupted Perimeter Supervision and Complete Signal Protection

To ensure an unbreachable perimeter, your entry sensors must maintain a continuous, un-jammable data line back to the brain of your home. Standard consumer security kits communicate using open, one-way frequencies that can easily be blocked or spoofed by bad actors using basic radio-frequency transmitters.

Our advanced entry protection networks completely eliminate this risk through proprietary SiX™ Two-Way Encrypted Technology. Every door and window sensor we deploy executes continuous, bidirectional cryptographic handshakes with your ADT Command panel using military-grade 128-bit AES encryption.

The central hub actively supervises every single sensor zone on the perimeter, verifying signal strength and operational health around the clock. If an intruder attempts to use an electronic transmitter to jam the frequency, or tries to physically pry the plastic sensor casing off your frame, the panel instantly logs the tamper anomaly and triggers an immediate high-priority alarm state before the entry point can even be fully breached.

Our certified low-voltage technicians paint-match and align the sensors flush along your window tracks and door frame sashes, ensuring they remain completely inconspicuous and blend seamlessly into your home’s interior design.

No. Standard retail contact switches can sometimes be fooled by holding a strong magnet against the outside of the frame, but our advanced sensors feature integrated anti-tamper magnetic balancing. If an intruder attempts to introduce an external magnetic field to trick the sensor, the hardware immediately detects the magnetic anomaly, flags it as a tamper event, and transmits an immediate priority alarm packet straight to your central panel.

Our sensors utilize proprietary SiX™ Two-Way Supervision to completely eliminate late-night low-battery guessing games. The contact sensor continuously transmits its exact power levels to your central ADT Command hub. When a battery drops below 20%, the system identifies the exact door or window location and pushes a clean maintenance alert to your smartphone dashboard weeks in advance, giving you plenty of time to swap the long-life lithium cell during normal business hours.
