Frequently Asked Questions
Do no-contract security systems still call the police?
Only if you add optional professional monitoring, which most no-contract systems offer for $10-25/month. Without monitoring, you receive smartphone alerts and can call 911 yourself. Self-monitoring is free and works well for most homeowners.
Are DIY security systems as reliable as professional ones?
Yes. Systems from SimpliSafe, Ring, and Abode use the same sensor technology as professionally installed systems. The main difference is you install them yourself, which saves $100-200 in installation fees and lets you take the system when you move.
What happens if my internet goes down?
The best no-contract systems include cellular backup that keeps monitoring active during internet outages. Some also have battery backup for power failures. Look for systems with built-in cellular radios rather than WiFi-only connectivity for maximum reliability.
