Alarm Systems That Respond Before the Problem Escalates
A good alarm system is a deterrent, a detection tool, and a notification engine all in one. When properly designed and installed, it makes your property a hard target and gives you — or a monitoring center — immediate notice when someone attempts unauthorized entry. Cadena Security installs intrusion detection and alarm systems for businesses and homes across the DFW Metroplex.
Every installation starts with a site walk-through. We identify perimeter entry points, high-risk interior zones, and existing vulnerabilities before recommending a sensor layout. The goal is comprehensive coverage without nuisance alerts — a system that alerts when it should and stays quiet when it shouldn't.
What a Professional Alarm System Includes
Door & Window Sensors
Magnetic contact sensors on every key entry point. Immediate detection when a door or window is opened while the system is armed.
Motion Detectors
Passive infrared (PIR) sensors for interior spaces and outdoor zones. Configured to minimize false alarms from pets, HVAC airflow, or vehicle headlights.
Glass Break Sensors
Acoustic sensors that detect the frequency of shattering glass — catching break-in attempts through windows that would bypass a door contact sensor.
Control Panel & Keypad
The brain of the system. Arming and disarming via keypad, key fob, or smartphone app. Communicates with all sensors and triggers alerts when any zone is tripped.
How Alarm Monitoring Works
When an alarm triggers, the system sends an alert — to you via app notification, to a professional 24/7 monitoring center, or both. Monitoring centers can dispatch appropriate emergency services when you cannot respond. Cadena Security can discuss monitoring options that fit your needs and budget, and integrate with third-party monitoring providers you may already use.
Commercial vs. Residential Alarm Systems
Commercial alarm systems typically cover larger footprints with more zones, integrate with access control and video surveillance, and may need to satisfy insurance carrier requirements or local ordinance standards. Residential systems are simpler but still benefit from professional-grade hardware and proper sensor placement. Both get a site assessment at Cadena Security before any quote.
Alarm + Video Integration
When an alarm triggers, pairing it with video surveillance lets you see exactly what caused it — instantly. This is increasingly important for verifying whether an event requires dispatch or was a false alarm. See our full security service offerings or contact us for a free quote.
