The push button can be mounted on a door, wall, gate, or entrance.<\/li>\n<li aria-level=\"1\">Improved aesthetics: No signal wiring is required between the doorbell push button and the chime receiver, helping reduce installation work and maintain a cleaner appearance.<\/li>\n<li aria-level=\"1\">No renovation required for installation: Many house fa\u00e7ades are finished with granite or decorative stone, which is difficult to drill. Homeowners may also prefer not to drill because doing so could damage or crack the stone surface. If wiring is required only to install a single push button, a wireless push button is a more suitable option.<\/li>\n<li aria-level=\"1\">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 aria-level=\"1\">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 aria-level=\"1\">Low-quality push buttons with poor water resistance may fail after a short period of outdoor use.<\/li>\n<li aria-level=\"1\">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 aria-level=\"1\">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 aria-level=\"1\">Kawasan is an established brand in the\u00a0<a href=\"https:\/\/thegioidienthongminh.com\/danh-muc\/chuong-cua-bao-khach\/\" target=\"_blank\" rel=\"noopener noreferrer\">doorbell and visitor chime<\/a>. The products come with a 2-year warranty, and the product service life is guaranteed to be more than 5 years. Customers are also supported by a professional sales consulting team and timely technical assistance.<\/li>\n<li aria-level=\"1\">The operating range of the wireless doorbell has been improved. 433MHz RF transmission technology provides strong signal transmission from the push button to the chime receiver, where the ringtone is generated. The chime can be heard throughout the house, with a signal transmission range of approximately 20\u201370 m.<\/li>\n<li aria-level=\"1\">Expandable pairing capability provides greater convenience for large and multi-storey houses. One KAWASAN doorbell receiver can be paired with up to 4 push buttons, while one push button can be paired with multiple chime receivers. This helps homeowners avoid the additional cost of purchasing a complete doorbell set with one receiver and one push button for every area of the house.<\/li>\n<li aria-level=\"1\">Independent RF receiving channel: With this feature, your wireless doorbell will not interfere with your neighbor's doorbell. Each system is paired using a separate coded channel, helping prevent situations where pressing your push button causes your neighbor's chime to ring, or vice versa.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>M\u00e3 s\u1ea3n ph\u1ea9m: DB668HT\u00ecnh tr\u1ea1ng:C\u00f2n h\u00e0ng<\/p>","protected":false},"featured_media":16622,"comment_status":"open","ping_status":"closed","template":"","meta":{"_yoast_wpseo_focuskw":"chu\u00f4ng c\u1eeda kh\u00f4ng d\u00e2y","_yoast_wpseo_metadesc":"Chu\u00f4ng c\u1eeda kh\u00f4ng d\u00e2y DB668H kho\u1ea3ng c\u00e1ch t\u00edch h\u1ee3p gi\u1eefa 2 th\u1ebft b\u1ecb 20m ~ 70m tu\u1ef3 v\u1eadt c\u1ea3n, c\u00f3 \u0111\u1ebfn 32 ki\u1ec3u chu\u00f4ng v\u00e0 4 m\u1ee9c \u00e2m l\u01b0\u1ee3ng tu\u1ef3 ch\u1ec9nh","_yoast_wpseo_focuskeywords":"","_yoast_wpseo_keyword_synonyms":""},"product_cat":[505,41,85],"product_tag":[1220,720,1223,1219,1227,1222,723,1228,1229,1230,1226,1027,1038,718,1039,1217,1218,719,1221,1231,1232,621,1224,1225],"class_list":["post-6369","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-chuong-cua-khong-day","product_cat-chuong-cua-chuong-bao-khach","product_cat-hang-khuyen-mai-soc","product_tag-chuong-bam-cua","product_tag-chuong-bam-cua-khong-day","product_tag-chuong-bao-cua-ra-vao","product_tag-chuong-bao-dong-khong-day","product_tag-chuong-bao-khach-cho-cua-hang","product_tag-chuong-bao-khach-kawasan","product_tag-chuong-bao-khach-khong-day","product_tag-chuong-bao-trom","product_tag-chuong-cam-bien-bao-dong","product_tag-chuong-cam-bien-kawasan","product_tag-chuong-cong-ko-day","product_tag-chuong-cua","product_tag-chuong-cua-bao-khach","product_tag-chuong-cua-khong-day","product_tag-chuong-cua-thong-minh","product_tag-chuong-dien-khong-day","product_tag-chuong-goi-phuc-vu-khong-day","product_tag-chuong-khong-day","product_tag-chuong-nha","product_tag-dau-bao-cam-bien","product_tag-dau-chuong-bao-khach","product_tag-kawasan","product_tag-pin-chuong-cua","product_tag-pin-chuong-cua-khong-day"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v24.9 (Yoast SEO v24.9) -
