Unlike traditional wireless doorbells that require the indoor receiver to occupy a valuable AC power outlet, the A30-PRO receiver runs on three standard AAA batteries. This allows you to place the chime anywhere you need it—on a bedside table, a living room coffee table, or even carry it in your pocket while moving around the house, ensuring you never miss a visitor or an emergency call.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eLong-Range 433MHz Signal Penetration\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eOperating on the highly stable 433MHz radio frequency, this doorbell ensures reliable signal transmission through thick walls and multiple floors. It boasts an impressive maximum range of 280 meters in open spaces and a practical 20 to 50-meter range indoors with obstacles. Whether you live in a multi-story village house or work in a partitioned office, the signal will consistently reach the receiver to trigger the 29mm large speaker and the visual LED alert.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003ePro Tip from Our Technicians\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eAlways avoid mounting the outdoor transmitter directly onto metal surfaces like iron gates or stainless steel doors. Our Sham Shui Po security specialists warn that large metal objects act as a shield, severely blocking the 433MHz wireless signal and reducing the doorbell's range. If you have a metal gate, we recommend sticking the transmitter to the adjacent concrete wall or wooden door frame for optimal performance.\u003c\/span\u003e\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":48199907967127,"sku":"21PS000676","price":48.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/a30-pro-wireless-battery-doorbell-silver-main.jpg?v=1788416385","url":"https:\/\/scccltd.com\/products\/wireless-battery-doorbell-silver","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
