SimpliSafe setup
Every sensor is numbered. The companion app walks you through placing each one. The base station auto-discovers sensors. Most buyers complete setup in 20–30 minutes. No technical knowledge required. Same-day activation is standard.
ADT Self Setup
ADT Self Setup requires creating an ADT account, configuring the system through the ADT app, and registering sensors. The process is manageable but involves more steps than SimpliSafe. Google Nest integration requires additional configuration but works well once set up.
Bottom line on setup: SimpliSafe is faster and simpler. If technical setup is a concern, SimpliSafe is the safer choice. ADT Self Setup is fine for buyers comfortable with app-based device configuration.
