DIY Self-Monitored
Homeowner installs cameras and sensors and monitors alerts via a smartphone app, without a professional monitoring contract.
- Lower ongoing cost — no required monthly monitoring fee in many cases
- No long-term contract required
- Flexible to expand or modify the system yourself
- Relies on you seeing and responding to alerts personally
- No automatic emergency dispatch if you miss an alert
Professionally Monitored
A security company monitors the system 24/7 and dispatches emergency services when needed, often with professional installation.
- 24/7 monitoring with automatic emergency dispatch
- Professional installation in many plans
- Can provide peace of mind if you're often unavailable to respond to alerts
- Ongoing monthly cost
- Often requires a contract term, sometimes with cancellation fees
Which one makes sense for you?
DIY self-monitored systems cost less over time and offer more flexibility, appealing to tech-comfortable homeowners who will reliably respond to app alerts. Professionally monitored systems cost more monthly but provide guaranteed emergency dispatch, which may be worth it for households wanting that added layer of response.
Key cost factors.
- Whether guaranteed emergency dispatch matters to you
- Contract length and cancellation terms
- Number of entry points, sensors, and cameras needed
- Whether professional installation is included or required
Before you decide.
- What's the total contract length and cancellation policy?
- Do I own the equipment outright, or is it tied to the monitoring contract?
- What's the actual monthly cost including any required add-ons?
Frequently asked questions.
Can I switch from DIY to professional monitoring later?
Many systems allow adding professional monitoring later, though this varies by brand — check compatibility before purchasing equipment if you might want to upgrade.
