Running new cables through concrete walls, tearing open finished corridors, and disrupting residents for weeks\u2014it\u2019s expensive, messy, and often simply impractical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In China alone, nearly a thousand old residential communities face intercom system upgrades every year. The traditional approach of replacing analog voice intercoms with digital video systems requires extensive rewiring, drilling through walls, and creates noise and dust that disturbs residents. The result? High costs, long construction timelines, and frustrated tenants.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But what if there was a way to upgrade to a modern video intercom system&nbsp;<strong>without running a single new cable<\/strong>?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is. It\u2019s called&nbsp;<strong>2-wire video intercom technology<\/strong>\u2014and FARHD has mastered it.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"the-solution-two-wires-one-complete-upgrade\" class=\"wp-block-heading\">The Solution: Two Wires.
