Clear Costs. Protection That Fits.

Your security system should fit your property and priorities. We explain equipment, installation and ongoing service costs separately, so you understand your options before making a decision.

Equipment & Installation

Essential Protection

Approximate installed investment

$750–$1,200

An example range for essential protection, not a fixed-price package.

A professionally installed foundation for the primary entry points and core areas of a smaller property.

  • Core intrusion protection
  • Professional programming and testing
  • System setup and customer guidance

Final pricing depends on your property, coverage, equipment and installation requirements. Larger systems and additional features cost more. Monitoring and cloud-video services are quoted separately.

Ongoing Service

Professional Monitoring

Starting at

$31/month

Monitoring service is separate from equipment and installation.

When your system sends an alarm, trained monitoring professionals follow the appropriate verification and notification procedures.

  • 24/7 professional alarm monitoring
  • Alarm handling based on account instructions
  • Stone’s remains your local service contact

Your rate depends on compatible equipment, communication options and selected services. We explain the monthly cost, included features and any applicable agreement terms before you approve service.

Already have security equipment?

You may be able to reuse compatible equipment. We’ll evaluate its condition and capabilities, explain what can stay, and recommend upgrades where needed.

Free, no-obligation recommendations and pricing for your home or small business.
