What is the difference between DIY and professionally installed security systems?

DIY systems (SimpliSafe, Ring Alarm, Wyze) install in 1-4 hours without tools — sensors use adhesive mounts or simple screws, and the app guides setup. Professional installation typically costs $100-300 and is usually required for traditional providers like ADT. DIY systems have caught up in reliability and features, and most security experts now recommend them for most homeowners. Professional installation only makes sense for complex setups with many cameras or when running wired sensors through walls.

Do I need professional monitoring or is self-monitoring enough?

For most households, professional monitoring is worth the $10-25/month cost. When an alarm triggers at 2am while you are asleep or away, professional monitoring contacts emergency services without any action required from you. Self-monitoring requires you to see the app alert, decide it is real, and call 911 yourself — adding critical minutes to response time. If you are a light sleeper who always has their phone, self-monitoring works. For families, elderly household members, or extended travel, professional monitoring is recommended.

Which home security system has no monthly fee?

Abode offers basic self-monitoring with no monthly fee — you pay for the hardware, and the app alerts you for free. Wyze has a 30-day trial then requires a $1.99/month plan for most features. Ring Alarm's self-monitoring is free (app alerts only) but professional monitoring starts at $10/month. The catch with truly free systems: no cellular backup, no professional monitoring response, and often limited cloud storage for cameras. For true emergency response, some monthly fee is unavoidable.

Can a home security system prevent break-ins or just detect them?

Security systems primarily detect and deter rather than physically prevent intrusion. Studies show that homes with visible security cameras and alarm signs are significantly less likely to be targeted by burglars. The deterrence effect — burglar sees sign and moves on — is the primary crime-prevention benefit. Detection and alarm response minimize losses if a break-in occurs by shortening the time before police arrive. Combining visible cameras, alarm signage, and motion-activated lights creates the strongest deterrent combination.

What happens to my security system if the internet goes down?

Systems without cellular backup become vulnerable during internet outages from power cuts or cable cuts by intruders. Cellular backup maintains the alarm connection to monitoring centers even with no Wi-Fi. SimpliSafe, Ring Alarm Pro, and ADT all include cellular backup with monitoring plans. Some systems require upgrading to a higher-tier plan to enable cellular backup. Check whether cellular backup is included or an add-on before purchasing — it is one of the most important security features.
