Overview
SimpliSafe SimpliSafe Motion Sensor setup takes under 15 minutes for most users — if you're stuck, the steps below target the specific points where installs stall.
This guide covers the installation of the SimpliSafe Motion Sensor, including placement selection for best room coverage, adhesive or screw mounting, and base station pairing. SimpliSafe motion sensors use passive infrared technology and communicate wirelessly to the SimpliSafe base station without requiring WiFi or additional hubs.
Why This Happens in Real Homes
SimpliSafe motion sensors are PIR and cover a room best from a corner at 7-8 feet, angled so people crossing the room pass through the detection fan. Mount too low and pets enter the field; aim at a vent or sunny window and you get false alarms from moving heat.
Start by corner-mounting at the right height, angled across the main walk path and slightly up so floor-level pet movement stays under the beam, away from vents and windows. Pull the battery tab, confirm it's in base range, and add a second sensor for a large open space one can't fully cover.
