Why professional monitoring beats DIY
Self-monitored systems rely on you to respond to every alert — while you're sleeping, on a flight, or in a meeting. Professional monitoring means trained operators watch your home 24/7 and dispatch police, fire, or medical services automatically.
Both Vivint and ADT offer professional installation, proven hardware, and monitoring contracts that insurance companies love. Most homeowners see a 5–20% reduction in home insurance premiums — which offsets a meaningful portion of the monthly cost.
- ✓ 24/7 monitoring — even when your phone dies
- ✓ Cellular backup — works if your internet goes down
- ✓ Automatic emergency dispatch — no action required
- ✓ Insurance premium discounts — pays for part of the cost
★ Our Top Security System Picks
Both systems are excellent. Your best choice depends on whether you prioritize smart home automation (Vivint) or brand trust and flexibility (ADT).
