A SMART START! Everything you need to start your smart home security system: two Outdoor Motion Sensors with one SpeakerHub. Supports 300+ devices from our full product line. Add more hubs for large homes, high-rise condo buildings, etc. Four AA batteries, good for 2+ years standby, are included! | PROTECT YOUR PERIMETER and prevent crime at your property line! With our LoRa-based up to 1/4 mile wireless range, you can now put security devices where it was once very costly, or impossible. Remote buildings, sheds, barns, fencelines, driveway entrances (great for driveway alerts, too!) | WHY PAY A MONTHLY FEE, when you can protect it for free? Self-monitor and save when you take advantage of our many ways to be notified of alarms and off-normal events in and around your home or business. See the"Know Now!" section below for more info! | WIRE LESS! Self-powered and wireless, just install the sensor wherever it is needed: mount it to a wall, post or column, even a tree! No wires, no trenching, no conduit, no electrician needed! | DEVICE-TO-DEVICE PAIRING allows for two or more devices, like your Outdoor Motion Sensor and a Siren Alarm, to be paired together, so they will operate when needed, without WiFi, internet, even without AC power (battery-powered or backed-up devices)! Great for cars & trucks, RVs and boats, storage units, construction sites, hunting cabins and more! | EXTREME LONG RANGE: Latest technology LoRa-based wireless allows you to place your sensor 1000 or more feet away from the hub! Superior obstruction penetration means your sensor can work in the basement, in the garage, and in sheds and outbuildings. | BETTER TOGETHER!
