An alarm system's cost depends on far more than just the keypad and a few sensors — the number of protected zones, whether it's professionally monitored, and how it integrates with cameras or access control all move the price. Understanding these pieces helps you get an accurate quote instead of comparing unlike packages.

What Goes Into an Alarm System
Quick answer: A complete alarm system includes a control panel, a keypad, door and window sensors, motion sensors, and typically a monitoring connection — either cellular or internet-based.
The control panel is the system's brain, processing input from every sensor and triggering an alarm or monitoring notification. See our door, window and motion sensor placement guide for how sensors are chosen and placed.
Alarm System Installation Cost by Type
Quick answer: A basic residential alarm system typically runs $300–$800 installed. A fuller residential system with more sensors typically runs $800–$2,000. Commercial systems typically run $1,500–$6,000+ depending on square footage and zone count.
| System Type | Estimated Cost Range |
|---|---|
| Basic residential (few doors/windows) | $300–$800 |
| Full residential (motion, more zones) | $800–$2,000 |
| Commercial system | $1,500–$6,000+ |
Figures are general starting ranges for planning purposes only, not a quote.
Monitoring Cost
Professional 24/7 monitoring typically runs $20–$60 per month, depending on the monitoring provider and whether the system includes cellular backup, video verification, or smart-home integration. Self-monitored systems (app notifications only, no monitoring center) avoid this monthly cost but rely on the property owner to respond directly.
What Drives the Price Up or Down
- Number of doors, windows and zones — more protected points mean more sensors and labor.
- Wired vs. wireless sensors — see our wired vs. wireless alarm guide for how these compare.
- Professional monitoring — adds an ongoing monthly cost but ensures a response even when you can't respond directly.
- Integration with cameras or access control — adds design and programming time to a combined system.
Code and Compliance
Commercial alarm systems in many jurisdictions require a false-alarm permit from local police or fire departments, and some commercial buildings need alarm interconnection with fire/life-safety systems. Installers in Texas are licensed through the TDLR — ours is License #B31188501.
Alarm Installation Across Dallas, Fort Worth and Allen
We install residential and commercial alarm systems across Dallas, Allen, Plano and Frisco, and can confirm any local permit requirements as part of the project.
Residential vs. Commercial Alarm Systems
Residential systems typically cover entry doors, ground-floor windows, and interior motion sensors, often paired with security cameras.
Commercial systems typically cover more zones and integrate with access control and cameras — see our commercial security system installation guide.
Common Mistakes
- Under-protecting a property by skipping motion sensors in favor of door/window contacts alone.
- Choosing self-monitoring for a property that's frequently unoccupied.
- Not confirming local false-alarm permit requirements before a commercial install.
Installation Process
- Site assessment — walking the property to plan sensor placement and zone count.
- Written estimate — itemized by hardware, labor and monitoring plan.
- Installation and programming — mounting sensors, wiring, and configuring the panel.
- Monitoring activation — connecting to a monitoring center if selected.
- Walkthrough — showing you how to arm, disarm, and respond to alerts.
Questions to Ask Before Hiring
- Are you licensed and insured in Texas? (We are — TDLR License #B31188501.)
- What monitoring options do you offer?
- Can this integrate with our cameras or access control?
- Will you give a written, itemized estimate?
Glossary: Terms Worth Knowing
| Zone | A single sensor or group of sensors monitored as one unit on the panel. |
| Professional Monitoring | A monitoring center that responds to alarm triggers and contacts you or emergency services. |
| Cellular Backup | A connection method that keeps the system reporting even if internet or phone lines are down. |
