Today, we will walk you through the basic wiring principles of our&nbsp;<strong>10\u2011inch 2\u2011wire video intercom system<\/strong>&nbsp;\u2013 from cable selection to connecting the indoor monitor and outdoor station.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether you are a professional installer or a DIY\u2011minded homeowner, this guide will help you understand how to set up a 2\u2011wire system correctly.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"what-is-2-wire-technology\" class=\"wp-block-heading\">What Is 2\u2011Wire Technology?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike traditional analog systems that require separate wires for power, audio, and video (often 4 or more wires), a 2\u2011wire system transmits&nbsp;<strong>power, video, audio, and control signals<\/strong>&nbsp;over a single pair of ordinary two\u2011core cables. This dramatically simplifies wiring \u2013 especially for retrofit projects where existing two\u2011core wires (e.g., old intercom lines, telephone wires) can be reused.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key advantages:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>No polarity \u2013 connect either way, no risk of reverse polarity damage.<\/li>\n\n\n\n<li>Long transmission distance \u2013 up to 100 metres (with \u22650.5mm wire).<\/li>\n\n\n\n<li>Low material cost \u2013 standard 0.5mm\u00b2 or 0.75mm\u00b2 two\u2011core cable is inexpensive and widely available.<\/li>\n\n\n\n<li>Minimal wall damage \u2013 ideal for upgrading old buildings without pulling new cables.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"system-components-overview\" class=\"wp-block-heading\">System Components Overview<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A basic 2\u2011wire villa or apartment kit includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Outdoor station (doorbell)<\/strong>\u00a0\u2013 with camera, microphone, speaker, call button, and optional RFID card reader.<\/li>\n\n\n\n<li><strong>Indoor monitor<\/strong>\u00a0\u2013 10\u2011inch IPS touchscreen, speaker, microphone, unlock relay, and power input.<\/li>\n\n\n\n<li><strong>Power supply<\/strong>\u00a0\u2013 usually a 15V or 18V DC adapter (central power supply can also be used for multiple units).<\/li>\n\n\n\n<li><strong>2\u2011core cable<\/strong>\u00a0\u2013 connects the outdoor station to the indoor monitor (and optionally to additional indoor monitors).<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"wiring-diagram-basic-setup-1-outdoor-1-indoor\" class=\"wp-block-heading\">Wiring Diagram \u2013 Basic Setup (1 Outdoor + 1 Indoor)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The simplest configuration: one outdoor station connected to one indoor monitor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">text<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">[Outdoor Station] ---- (2\u2011core cable) ---- [Indoor Monitor] ---- [Power Supply]<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Step\u2011by\u2011step wiring instructions:<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Run a 2\u2011core cable<\/strong>\u00a0from the outdoor station location to the indoor monitor location.\n<ul class=\"wp-block-list\">\n<li>Use \u22650.5mm\u00b2 copper wire.
