A wireless push button is a practical solution because it does not require concealed signal wiring.<\/li>\n<li>Convenient battery replacement: The wireless push button uses a replaceable battery that typically lasts around 6 months. The chime receiver can be plugged directly into a 220V power outlet.<\/li>\n<li>Expandable system: In large or multi-story homes, a single chime receiver may not be audible everywhere.

When installed in multi-story buildings, pressing the push button may fail to activate the chime on higher floors.<\/li>\n<li>Low-quality push buttons with poor water resistance may fail after a short period of outdoor use.<\/li>\n<li>Limited or no expansion capability, requiring users to purchase additional complete doorbell sets for other areas of the house, especially in multi-story homes.<\/li>\n<li>Low initial purchase price but poor durability of less than 2 years, resulting in higher replacement and repair costs over time.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"VI_SAO_NEN_MUA_CHUONG_CUA_KHONG_DAY_KAWASAN\"><\/span>WHY SHOULD YOU CHOOSE A KAWASAN WIRELESS DOORBELL?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Kawasan is an established brand in the wireless doorbell sector. Products are supported by a 2-year warranty and are designed for long-term use. Professional sales consultation and technical support are also available.<\/li>\n<li>The wireless transmission range has been improved. RF433MHz technology transmits signals from the push button to the chime receiver with good sensitivity and reduced interference.<\/li>\n<li>The system supports flexible expansion for larger or multi-story homes. One Kawasan chime receiver can be paired with up to 4 push buttons, while one push button can be paired with multiple chime receivers. This helps reduce the need to purchase multiple complete doorbell sets for different areas.<\/li>\n<li>Separate wireless coding: Each paired system uses its own signal code, helping prevent interference between neighboring doorbells. This reduces the possibility of pressing your push button and accidentally activating a neighbor\u2019s chime, or vice versa.<\/li>\n<\/ul>\n<div id=\"attachment_6194\" class=\"wp-caption aligncenter\">\n<figure id=\"attachment_16515\" aria-describedby=\"caption-attachment-16515\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-16515\" title=\"Kawasan wireless doorbells are trusted by many users.\" src=\"https:\/\/kawasan.vn\/wp-content\/uploads\/2023\/11\/chuong-cua-khong-day-DB658-11.png\" alt=\"Chu\u00f4ng kh\u00f4ng d\u00e2y Kawasan \u0111\u01b0\u1ee3c nhi\u1ec1u ng\u01b0\u1eddi tin d\u00f9ng\" width=\"600\" height=\"442\" \/><figcaption id=\"caption-attachment-16515\" class=\"wp-caption-text\">Kawasan wireless doorbells are trusted by many users.<\/figcaption><\/figure>\n<\/div>\n<h3><span class=\"ez-toc-section\" id=\"TAI_SAO_NEN_CHON_KAWASAN\"><\/span><b>WHY CHOOSE KAWASAN?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A leading Vietnamese brand in the fields of automatic electrical equipment, security, safety, and smart electrical devices since 2007, as well as residential LED lighting and solar lighting since 2012.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">High durability with selected components \u2013 Stable operation even in harsh weather conditions<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Superior warranty policy \u2013 Repair support is available even after the warranty period if the product can still be restored<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Kawasan currently has its head office in Ho Chi Minh City, branches in Hanoi and Da Nang, and a production and assembly workshop in District 12, Ho Chi Minh City.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">24\/7 support service and a nationwide dealer network<\/span><\/li>\n<\/ul>\n<h4><span class=\"ez-toc-section\" id=\"CAM_KET_TU_KAWASAKAWASAN\"><\/span><b>KAWASAN COMMITMENT<\/b><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span style=\"font-weight: 400;\">Kawasan is committed to providing products <\/span><b>genuine \u2013 durable \u2013 safe<\/b><span style=\"font-weight: 400;\">, fully meeting technical standards and practical usage requirements.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">All products are covered by warranty <\/span><b>free of charge for 24 months<\/b><span style=\"font-weight: 400;\">, <\/span><b>1-for-1 replacement within 30 days<\/b><span style=\"font-weight: 400;\"> if it is a technical defect.
