THE PEOPLE BEHIND THE SYSTEM
Know who builds it.
Know who supports it.
Manufacturing with a defined scope
We develop video intercoms and smart locks with in-house R&D, production and quality-control teams. Selected manufacturing partners support our smart control panel portfolio.
Engineering before equipment
Our project service starts with infrastructure assessment and system planning. Technical feasibility, responsibilities and the scope of work are agreed before execution.
OEM/ODM, coordinated directly
Hardware customization, system integration and delivery coordination are managed through a dedicated LEONDARX contact. Customization is scoped around the selected product and project requirements.
Questions before
the specification.
Installation, compatibility and customization deserve clear answers before you commit to hardware.
Can an existing two-wire installation be reused?
Our Tuya two-wire intercom range is designed for retrofit projects. Reuse depends on the existing cable, topology, cable runs and power arrangement. Share the site wiring details so the proposed door stations and indoor monitors can be checked as a complete system before ordering.
Will every lock, panel and intercom work together?
Compatibility must be checked at model and system level. An RS485 port, Wi-Fi connection or app name alone does not establish interoperability. For example, SK Pad Mini lists RS485, wired networking and 2.4 GHz Wi-Fi; the connected devices and required integration still need to be specified.
What can be customized for an OEM/ODM order?
Smart-lock customization options described in our product materials include branding, panel color, materials, packaging and app interface requirements. Availability, engineering work, minimum quantity and schedule depend on the model and customization scope; confirm these in the quotation.
What information should I send for product selection?
Start with the project country, building type, required functions, approximate quantity and target schedule. For locks, include door material, thickness and lock-body dimensions. For intercoms and controls, include the wiring layout and the devices or platform you need to connect. An early estimate is enough to start the discussion.
