Security systems typically cost between $100 and $1,500 for equipment, with monthly monitoring fees from $15 to $60 or more. The total depends on whether you choose a DIY setup or a professionally installed system, the number of sensors and cameras, and whether you add 24/7 monitoring or smart-home integration.

Types of Security Systems and Typical Costs
DIY Wireless Systems
DIY systems like SimpliSafe, Ring Alarm, or Wyze range from $100 to $400 for basic kits. These include a hub, door/window sensors, and a motion detector. You pay no installation fee, and many work without a contract.
Professionally Installed Systems
Professional systems from ADT, Vivint, or Protect America run $300 to $1,500 for equipment, often with free installation if you sign a monitoring contract. These systems include hardwired sensors, high-resolution cameras, and dedicated control panels.
Camera-Only Systems
Standalone security cameras from brands like Arlo, Reolink, or Eufy cost $50 to $300 per camera. Multi-camera kits fall between $150 and $600. Local storage or cloud subscriptions add $3 to $10 monthly.
What Drives the Price
- Monitoring type: Self-monitoring is free; professional monitoring adds $15 to $60 monthly.
- Equipment count: More sensors and cameras increase upfront cost.
- Smart-home integration: Compatibility with Alexa, Google Home, or Apple HomeKit can add $50 to $200.
- Contract length: Longer contracts often waive equipment fees but lock you in.
- Installation: Professional installation adds $100 to $300 unless bundled.
Hidden and Ongoing Costs
Beyond equipment, watch for activation fees ($0 to $100), early termination penalties ($200 to $500), and cloud storage subscriptions ($3 to $15 monthly). Some providers also charge for cellular backup ($10 to $20 monthly) or advanced features like video analytics.
| System Type | Equipment Cost | Monthly Fee | Best For |
|---|---|---|---|
| DIY Wireless | $100–$400 | $0–$25 | Renters and budget-conscious users |
| Professional Installed | $300–$1,500 | $20–$60+ | Homeowners wanting hands-off monitoring |
| Camera-Only | $50–$600 | $0–$15 | Targeted video surveillance |
How to Choose
Start by assessing what you need: entry-level protection, full-home coverage, or video evidence. Compare total ownership cost over 24 or 36 months, not just the upfront price. A cheaper system with expensive monitoring can cost more long term than a pricier kit with self-monitoring.
