Upfront costs
| Item | Angi | HomeGuide |
|---|---|---|
| Basic equipment package | $200 – $400 (plus $20 – $300 per added sensor) | $199 – $599 |
| Installation (when charged) | $120 – $600 | $0 – $299 (with activation) |
| Activation fee | $0 – $230+ | included above |
SafeWise notes that most national providers, including Ring and SimpliSafe, charge nothing for DIY installation and activation, and that when professional installation is offered it typically runs $99 to $199.2 Angi adds that national companies often waive install fees entirely because monitoring contracts recoup the cost.1
Monitoring costs per month
| Source | Monthly monitoring |
|---|---|
| Angi | $10 – $65 |
| SafeWise | $8 – $60 (average $32.23) |
| HomeGuide | $25 – $50 |
SafeWise’s research separates DIY and professional systems: monitoring on DIY systems averages $24.26 a month versus $42.91 on professionally installed systems.2 At those averages, monitoring is the largest long-term cost of a system — $10 to $60 a month adds up to $600 to $3,600 over five years.2
Cost by system type (Angi)
| System type | Typical cost |
|---|---|
| Wireless | $200 – $2,000 (by camera count) |
| Wired | $800 – $1,600 installed |
| Standalone cameras or sensors | under $100 – $200 (self-monitored) |
Wired systems always require professional installation; wireless systems are simpler to install but often carry monthly fees.1
