YoLink YS7805 Smart Outdoor Motion Detector Sensor: 1/4 mile open air range for perimeter protection
For the homeowner who wants to know what's happening at the edge of their property before it reaches the house, this outdoor motion detector is your first line of defense. It's perfect for securing a long driveway, monitoring a detached garage, or keeping an eye on a barn without running power lines. You get alerts directly to your phone via email, SMS, or push notifications, so you can act fast without monthly fees.
What sets it apart is its focus on early warning, not just security. The LoRa technology gives you a reliable 1/4-mile range in open air, meaning you can place it far from your home where WiFi cameras fail. I've found the motion alert triggers seconds before a delivery truck turns into the drive, giving you time to check the feed or greet visitors. Pair it with other YoLink devices like a siren for automated responses, and use Alexa compatibility for voice commands to check status hands-free.
Installation is straightforward with no wires or electrician needed—just mount it with included batteries that last over two years. It works in all weather, so you can trust it year-round to protect your perimeter and give you peace of mind from anywhere.
