【Precise Radar Detection — A Reliable Home Guard】Unlike PIR sensors, Letwesaf uses 24GHz millimeter-wave radar to detect real movement—not heat. Smart filtering cuts false alerts from wind, sunlight, leaves, or brush. Detects reliably through bushes, fences, and light obstacles—even in total darkness. Compact design can be discreetly concealed without affecting detection performance.
【1/2 Mile Wireless Transmission Range — Early Alerts for Your Property】The receiver picks up alerts from up to 0.5 mile (800m) away—about 7 football fields—giving you time to react, prepare, or secure your property. Keeps you aware of approaching people, vehicles, or wildlife. Provides early alerts along key pathways—so you can take action sooner. Ideal for driveways, yards, farms, or camping areas.
【Customizable Detection Zone — Precise Coverage for Critical Areas】Creates a 3D rectangular detection zone, not just a straight line. Adjustable from 17×20 ft up to 50×20 ft, with motion tracking up to 75 mph. Customize coverage for key areas of your property—such as driveways, yards, barns, garages, gates, farmland, or even fishing spots. Detects intruders, vehicles, or wildlife early—giving you greater control and peace of mind.
【Off-Grid Security Alarm — Rechargeable & Easy Setup】Works completely offline—no WiFi, no setup stress. This compact alarm is an entirely independent system, ideal for remote properties and outdoor use. Built-in 3000mAh battery provides up to 48 hours (≈6 nights) protection and support solar panel charging for extended runtime. Easy to mount on fences, trees, barns, or campsites with a ball mount or rope.
【Full Weatherproof — Built for Outdoor Conditions】Designed to withstand harsh environments, Letwesaf meets IP66 waterproof and dustproof standards. Performs reliably in rain, snow, fog, dust, and extreme temperatures. Ideal for farms, ranches, driveways, yards, campsites, and remote properties—helping protect against intruders and wildlife.
【Expandable System — Up to 6 Sensors, Full 360° Coverage】Connect up to 6 sensors (sold separately) to one receiver to create a full 360° perimeter security system. Perfect for larger areas like farms, home front and back yards, pools, driveways, rural properties, or camping setups. Expand coverage to eliminate blind spots and stay fully aware of movement.
【Quick Start Tips】For the best experience, fully charge the device before first use. To help you operate it with ease and confidence, we’ve carefully updated the user manual. Please download the latest manual at the bottom of the page.
