What Actually Drives the Cost
Three factors determine your total cost: (1) how many entry points you need to cover — more doors and windows mean more sensors; (2) whether you want professional monitoring — this is the single largest ongoing cost driver; and (3) whether you choose DIY or professional installation — professional installation adds $100–$300 one-time but can save money long-term by ensuring optimal sensor placement that reduces false alarms and monitoring call-outs.
Our Recommendation by Budget
- Under $200 total: Ring Alarm 5-piece ($99.99) + self-monitoring
- Under $500/year: Ring Alarm + Ring Protect Plus ($10/month)
- Under $1,000/year: SimpliSafe + Core monitoring ($19.99/month)
