Dahua’s new line of expandable two-wire IP video intercom solutions is designed for multi-tenant commercial and residential buildings, as well as educational and medical facilities. The system allows tenants, property managers, and owners to manage keyless entry and visually communicate in real time with visitors. Each outdoor station includes a 2MP camera with up to 1080p resolution, seamless IR operation with a wide vertical and horizontal field of view. The non-polarized two-wire cabling system with bus-based cascading technology greatly improves cable utilization rate, reducing power supply wiring. Because it can be installed using existing wiring, the solution also offers flexibility and cost-effectiveness, allowing users to deploy the system to support multiple communication paths and technologies without rewiring their location, making it ideal for both new installations and upgrades of existing systems. This new system also supports standard Ethernet for flexibility if two-wire is not available. These solutions are highly customizable based on project requirements, with options such as dial buttons, fingerprint reader, Mifare card reader, LED indicators and more to ensure the system meets end users’ specific needs.
