ANJIELO SMART pitches 2-wire video intercom retrofit kit for legacy apartment buildings

Zhongshan Anjielo Smart Technology says its 2-wire video intercom retrofit kit can upgrade old apartment intercoms without replacing in-wall cabling. The system is aimed at property owners and contractors looking to reduce rewiring costs, installation disruption and tenant downtime in multi-family buildings.

Why it matters: - Apartment and condo intercom upgrades often get delayed because running new Ethernet cable through finished walls is costly and disruptive. - ANJIELO SMART is targeting that problem with retrofit hardware designed to reuse existing two-conductor wiring in occupied buildings. - The company says the approach cuts civil work, avoids drywall repair and reduces tenant disruption during modernization.

What happened: - Zhongshan Anjielo Smart Technology Co., Ltd. unveiled its 2-wire video intercom retrofit kit for multi-family properties. - The system is built around a non-polarity two-wire bus that carries power, full-duplex audio and 1080P digital video over existing doorbell lines. - The company operates an ISO 9001 certified manufacturing facility in Zhongshan, Guangdong, and exports to more than 20 countries. - The company made product details and quotations available through its official portal: More information.

The details: - The two-wire system uses symmetrical terminal routing, so installers can connect wires in either direction without polarity faults or short-circuit damage. - Central distributor hubs multiplex DC power, digital video, bidirectional audio and door lock control signals across existing unshielded two-core copper wire. - The system supports legacy wiring types including bell wire, unshielded twisted pair and flat telephone cable. - Dynamic impedance matching supports variable line lengths up to 100 meters. - For runs longer than 30 meters, the company recommends an independent power supply for the outdoor station to keep voltage stable. - The outdoor unit includes relay output contacts compatible with 12V electronic locks, magnetic locks and motorized sliding gate operators. - The outdoor station uses a 1080P CMOS camera, an automated mechanical IR-cut filter and 850nm infrared illumination. - The outdoor enclosure is built from aluminum alloy and is rated IP65 for weather protection and IK08 for impact resistance. - The hardware is designed to operate from -20 degrees Celsius to 60 degrees Celsius. - Indoor units come in 7-inch or 10-inch IPS capacitive touch monitor versions. - The displays offer 178-degree viewing angles and support multi-room expansion through master-secondary monitor addressing using ID 1 and ID 2. - The outdoor unit combines a 130-degree wide-angle lens with a PIR motion sensor. - Motion detection can trigger instant app alerts and local recording. - The system stores footage on an included 32GB TF card without recurring cloud fees. - The indoor monitor can show real-time weather and clock data in standby. - When a visitor presses the bell, the indoor screen shows the 1080P video feed and supports two-way audio, snapshot capture and door release. - Each indoor monitor includes a 2.4GHz Wi-Fi module that links to the resident’s home router. - The monitor forwards entry calls to the Tuya Smart mobile app through the Tuya Smart IoT cloud platform. - Residents can speak with visitors and trigger door latches from mobile devices. - ANJIELO SMART also provides technical manuals in English, German, French, Spanish and Italian. - The manuals include conductor loop resistance limits, wire-gauge transmission tables for 0.5 mm2, 0.75 mm2 and 1.0 mm2 conductors, and terminal schematics for multi-drop bus topologies. - The company says the hardware is certified to CE, FCC, RoHS, REACH and EAC standards.

Between the lines: - The product is aimed at a market where labor, demolition and resident displacement can cost more than the intercom hardware itself. - By adding Wi-Fi and app access inside the indoor monitor, ANJIELO SMART is trying to bridge a gap between legacy building wiring and modern smart-home expectations. - The multilingual documentation signals a push for international contractor adoption, not just domestic sales.

What's next: - Property managers, residential developers and low-voltage contractors can review specifications, wiring diagrams and volume factory quotations through ANJIELO SMART’s website. - The company appears positioned to compete on retrofit simplicity, international compliance and direct factory supply for renovation projects.

The bottom line: - ANJIELO SMART is betting that legacy buildings can get smart-video intercom features without the cost and mess of rewiring.
