This is especially true for old buildings, heritage properties, or already decorated homes \u2013 cutting new channels not only damages the interior but also significantly increases labour and material expenses.<\/p>\n\n\n\n<p>Our&nbsp;<strong>2-wire video intercom system<\/strong>&nbsp;is designed to solve this exact problem. It uses existing two-core cables (even old telephone lines or existing weak-current conduits) to simultaneously transmit video, audio, unlock signals, and power. No rewiring needed, installation time reduced by more than 50%, and project efficiency greatly improved.<\/p>\n\n\n\n<p>Whether you are a system integrator, security contractor, or property manager, this system will become your go\u2011to solution in the&nbsp;<strong>renovation and retrofit market<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"1-no-rewiring-protect-decorations-and-lower-costs\">1. No Rewiring \u2013 Protect Decorations and Lower Costs<\/h3>\n\n\n\n<p>Traditional video intercom systems often require dedicated multi\u2011core cables (4 cores or more) with strict specifications. For already occupied homes or fully decorated office buildings, rewiring means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Damaged walls and ceiling finishes<\/li>\n\n\n\n<li>Added labour for channelling, conduit laying, and restoration<\/li>\n\n\n\n<li>Longer construction periods, disrupting residents\u2019 daily lives<\/li>\n<\/ul>\n\n\n\n<p>Our 2-wire system uses&nbsp;<strong>non\u2011polarity two\u2011wire technology<\/strong>. With just two ordinary wires of 0.5mm\u00b2 or more (existing intercom wires, telephone lines, or even good\u2011quality two\u2011core power cables), it simultaneously transmits:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>HD video signal<\/li>\n\n\n\n<li>Two\u2011way audio signal<\/li>\n\n\n\n<li>Unlock control signal<\/li>\n\n\n\n<li>Device power<\/li>\n<\/ul>\n\n\n\n<p><strong>What this means for you:<\/strong><br>You can upgrade an old analog system to a modern video intercom without damaging any decorations. For historic buildings, high\u2011end finished residences, hotel renovations, etc., this is an irreplaceable advantage.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"2-reduced-installation-time-faster-delivery-more-profit\">2. Reduced Installation Time \u2013 Faster Delivery, More Profit<\/h3>\n\n\n\n<p>Time is money. In engineering projects, cabling typically accounts for 30%\u201350% of the total construction period. With a 2-wire system, installation steps are simplified to:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Verify that the existing two\u2011core wires in the conduits are in good condition (or reuse existing cables).<\/li>\n\n\n\n<li>Connect the door station, indoor monitor, and power supply according to the wiring diagram (no need to distinguish polarity).<\/li>\n\n\n\n<li>Power on and test.<\/li>\n<\/ol>\n\n\n\n<p>Compared to traditional 4-wire or IP network systems, you do not need to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Test wire order and polarity<\/li>\n\n\n\n<li>Run separate power cables<\/li>\n\n\n\n<li>Configure complex network switches or IP addresses<\/li>\n<\/ul>\n\n\n\n<p><strong>Real\u2011life example:<\/strong><br>A contractor took on a retrofit project for an old community with 48 apartments. Originally planned to use a 4-wire system with an estimated 15 days of work. Switching to our 2-wire system, the actual installation took only 6 days, labour costs were reduced by over 60%, and there were zero complaints from residents (almost no drilling or wall damage).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"3-improved-efficiency-one-installation-long-term-stability\">3. Improved Efficiency \u2013 One Installation, Long\u2011Term Stability<\/h3>\n\n\n\n<p>Beyond installation efficiency, the 2-wire system also delivers efficiency in maintenance and expansion:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Simple troubleshooting<\/strong>&nbsp;\u2013 Fewer wires mean faults are easier to locate.<\/li>\n\n\n\n<li><strong>Supports multiple devices in series<\/strong>&nbsp;\u2013 One indoor monitor can be connected in series with up to 4 additional indoor monitors or 2 door stations (with a 2-wire switch).<\/li>\n\n\n\n<li><strong>Plug and play<\/strong>&nbsp;\u2013 Indoor monitors automatically recognise door station calls, no complicated address code settings.<\/li>\n\n\n\n<li><strong>Compatible with mainstream electric locks<\/strong>&nbsp;\u2013 Directly controls electric strikes, magnetic locks, motor locks, etc., without additional relay modules.<\/li>\n<\/ul>\n\n\n\n<p>For property managers, this means lower operating costs and faster response times.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"4-perfectly-suited-for-renovation-and-retrofit-markets\">4. Perfectly Suited for Renovation and Retrofit Markets<\/h3>\n\n\n\n<p>Around the world, a large number of residential and commercial buildings have outdated or failing intercom systems. Homeowners and property managers want to upgrade to modern features like video intercom and mobile app remote control, but they do not want to damage their decorations.<\/p>\n\n\n\n<p>Our 2-wire system is tailor\u2011made for exactly these&nbsp;<strong>retrofit projects<\/strong>:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">Retrofit Scenario<\/th><th class=\"has-text-align-left\" data-align=\"left\">2-Wire Solution<\/th><\/tr><\/thead><tbody><tr><td>Old community intercom upgrade<\/td><td>Use existing two\u2011core wires, replace door stations and indoor monitors \u2013 achieve video intercom<\/td><\/tr><tr><td>Hotel room system renovation<\/td><td>No rewiring, fast installation, minimise room downtime<\/td><\/tr><tr><td>Office building access control retrofit<\/td><td>Use existing weak\u2011current conduits, add remote unlocking and mobile app control<\/td><\/tr><tr><td>Villa garden gate intercom<\/td><td>Use buried two\u2011core conduits to easily achieve long\u2011distance intercom (up to 100 metres)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Real\u2011life applications:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A high\u2011end apartment in Shanghai<\/strong>: Built in 2005, the original audio intercom system frequently failed.
