More features

• 【Precise Radar Detection — A Reliable Camping Companion】Unlike traditional PIR motion sensors that rely on heat and struggle in harsh conditions, Letwesaf radar motion alarm system uses advanced 24GHz millimeter-wave radar to detect real movement. Smart filtering reduces false alerts from wind, sunlight, leaves, or brush. This camping alarm can detect motion through tent, bushes, and light obstacles with consistent accuracy, helping reveal hidden threats even in total darkness for dependable outdoor security.
• 【1/2 Mile Wireless Transmission Range — React Before Danger Arrives】The receiver picks up alerts from the detector at up to 0.5 mile (800m) away—about 7 football fields—giving you enough time to react, retreat, or prepare. This long-range wireless signal keeps you informed and aware of approaching people, vehicles, or wildlife—ideal for camping, property monitoring, hunting, or driveway alarm use.
• 【Customizable Detection Zone — Precise Coverage for Critical Areas】Creates a 3D rectangular detection area, not just a simple straight line. Starting at 17×20 ft and expandable up to 50×20 ft, with motion tracking up to 75 mph, allowing flexible coverage for campsites, RVs, or properties such as farm, home, front porch, and garage. Accurately detects intruders, wildlife or vehicles, early for better response and full perimeter protection.
