1. Long Wireless Transmission Range - Both the motion detector and the plug-in receiver transmit alarm signals up to 800 meters (actual range will vary depending on the local terrain). It is an effective solution for monitoring long driveways or large properties. The system uses advanced wireless transmission technology (FHSS) to minimize signal interference from other wireless devices. 2. Long Motion Detection Range - The weatherproof motion sensor detects moving people or vehicles from 10 to 15 meters in front of it. Equipped with an advanced motion detection chip and optimized detection angle to reduce false alarms caused by leaves, small animals, sunlight, wind, and temperature changes. It features two adjustable sensitivity settings (Low = 10m; High = 15m), making it ideal for driveways, walkways, yards, garages, gates, pools, and other indoor or outdoor areas. 3. Wide Range of Applications - The wireless, weather-resistant motion sensor is suitable for monitoring various indoor and outdoor areas, including driveways, porches, gates, pools, garages, and sheds. Ideal for use in homes, businesses, and offices. The sensor operates reliably in all seasons, with a working temperature range of -30F to 150F. 4. Plug & Play, Easy Installation - Power the motion sensor with 3 x AA 1.5V alkaline batteries (batteries not included) and plug the receiver into a standard electrical outlet. The system is pre-paired before shipping. Mount the sensor on walls, fence posts, trees, or other surfaces. Installation can be completed in minutes.
