Outdoor radar motion sensor alarm system designed for campers, overlanders, RV travelers, and offgrid adventurers. Uses synchronized millimeterwave radar detectors to create a reliable 3D detection perimeter around tents, vehicles, and campsites. Key benefits Reliable perimeter alerts: Six synchronized millimeterwave radar sensors form a 45 by 20 ft 3D detection zone to detect humans and animals approaching your campsite. Low false alarms: Radar detection is unaffected by falling leaves, wind, rain, or ambient light, reducing nuisance triggers common with infrared or PIR systems. Longrange wireless signal: Receiver alerts instantly over up to 800 meters line of sight between the detectors and the receiver. Fast, tool setup: Install in about one minute using the 360 degree bracket and screw or strap mounting. No wiring, no network, no external light source required. Allweather operation: IP65 waterproof housing lets the system work in mountains, forest, desert, and other exposed environments. Flexible power options: Each radar unit runs about 48 hours per charge. The receiver can last up to 7 days per charge. Both units are rechargeable and compatible with solar charging for extended offgrid use. Technical highlights Detection technology: Six millimeterwave radar sensors synchronized for full coverage and 3D detection. Coverage area: 45 by 20 ft 3D detection zone around protected space. Wireless range: Receiver communication up to 800 meters line of sight. Mounting: 360 degree adjustable bracket; screw or strap attachment; no wiring needed. Weather rating: IP65 waterproof. Power: Radar units approximately 48 hours battery life; receiver up to 7 days; rechargeable and solar charging compatible. Operation: Detects movement day or night without relying on light or network connectivity. Practical use scenarios Tent perimeter protection at night: Mount the radar units around a tent or tarp to receive immediate alerts on the receiver inside the tent if a person or animal enters the detection zone. RV or vehicle security at remote campsites: Create a 3D detection perimeter around an RV or vehicle to detect approaching people or wildlife before they reach your camp. Basecamp or overland stopovers: Deploy multiple detectors around a small basecamp to monitor access points while maintaining battery or solar charging for extended stays. What it solves Prevents surprise approaches by people or animals in lowlight and offgrid settings. Reduces false alarms caused by environmental movement and weather. Eliminates the need for permanent wiring, network access, or external light sources. Who should consider it Backpackers, campers, and overlanders who need a quickdeploy security perimeter. RV and van lifers who want remote perimeter alerts while sleeping or away from the vehicle. Hunters, photographers, and remote workers who need reliable motion detection in isolated locations. This radar motion sensor alarm system combines millimeterwave detection, longrange wireless alerts, quick installation, and allweather durability to provide dependable perimeter awareness for outdoor activities.
