This device is a GPS-based wireless fence system and cannot be used indoors or in small enclosed areas. Its functionality depends on a stable GPS signal. Buildings, trees, or other obstructions may interfere with signal reception and affect positioning accuracy (if your environment has many obstructions, please choose carefully). 2. For first-time use, setup must be completed in an open outdoor environment to ensure stable GPS signal reception. 3. When the GPS signal strength is below level 2, the device will not trigger the fence function. 4. It is recommended to set the center point only when the GPS signal strength reaches level 3 or above (maximum level 5) to ensure positioning accuracy.\u003c\/li\u003e\n\u003cli\u003eCustomizable Flexible Boundary Shapes: Break beyond the limitations of traditional circular fences by creating multi-point or curved boundaries.
