This article is about the Original SimpliSafe system. If you purchased a new system in 2018 or later, you likely have the All-New SimpliSafe. If you're not certain which system you have, you can tell the difference here.
No. Everything you need to set up the SimpliSafe Home Security System is included. If you do have access to a computer, you will have access to additional features and settings, but it is not required. Just plug your Keychain Remote (which has a built in USB device) into a USB port of your computer and the SimpliSafe Easy Setup Wizard will launch and guide you through setting up and using your home security system.
However, the SimpliCam and Video Doorbell Pro do require WIFI and access to the SimpliSafe app through either Google Play Store or the iOS App Store.
