It operates on its own without requiring a smart hub, Wi-Fi, smartphone app, or any subscription service. When the two magnetic components are separated (i.e., the door or window is opened), the 90dB alarm triggers immediately and automatically.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I install the wireless magnetic security sensor?\u003c\/h4\u003e\n\u003cp\u003eA: Installation is quick and easy. Simply attach one part of the sensor to the door or window frame and the other part to the moving door or window panel using the included adhesive backing. No drilling or wiring is required. The sensor is ready to use right out of the box.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use multiple sensors to cover my entire home or office?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. Each sensor works independently, so you can place as many as you need across all entry points — front doors, back doors, windows, sliding doors, cabinets, and more. Choose the 5-pack or 10-pack to cover more areas at a better value.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
