One downside to Scout Alarm is that you must pay a monthly fee $9. 99 to use the system, but this fee pays for built
in cellular backup, which is often more expensive with other DIY home security systems. There's no contract so you can cancel service if you don't need it. You can also upgrade a Scout Alarm system to include professional monitoring $19. 99/month, so you can get extra protection when you're unable to monitor your home yourself. This system is the easiest to install as it walks you through every step of the setup process in the mobile app, taking about 10 minutes to install. Scout Alarm works with the smart home platforms from Amazon, Nest and IFTTT. When we tested Scout's siren, it wasn't as loud as other security alarms we tested, but it is loud enough that other sounds in your home shouldn’t drown it out. Scout's one year
