A home security cost calculator estimates the upfront equipment and installation cost plus monthly monitoring fees based on your coverage needs and system type.
What Does a Home Security System Cost?
Home security costs vary widely based on system type, coverage area, and monitoring plan. A DIY system with basic monitoring starts around $200-300 total for year one, while a professional monitored system runs $1,000-2,000 in the first year.
Key Cost Factors
Equipment: control panel ($50-200), sensors ($15-40 each), cameras ($80-250 each). Installation labor adds $100-500 for professional systems. Monthly monitoring ranges from free (self) to $60+ for full-featured plans with video storage and cellular backup.

FAQ
How much does a home security system cost?
A basic DIY system costs $100-400 upfront with $10-25/month monitoring. Professional installation runs $300-1,500+ with $30-60/month monitoring. Smart home integrations add $200-500 to setup costs.
Is professional monitoring worth it?
Professional monitoring averages $25-50/month but provides 24/7 response even when you're asleep or can't answer your phone. Self-monitoring is free but relies entirely on you noticing alerts.
What is the difference between DIY and professional installation?
DIY systems (Ring, SimpliSafe, Wyze) are cheaper and portable. Professional systems (ADT, Vivint) include installation labor, long-term contracts, and equipment guarantees. DIY is often 50-70% cheaper upfront.
How many sensors do I need?
Count exterior doors and first-floor windows as a minimum. A typical 3-bedroom home needs 4-6 door/window sensors, 1-2 motion detectors, and 1 control panel. Add cameras for visual verification.
