Los productos de la marca Dahua vendidos por Setik SRL pueden ser entregados como productos OEM, es decir, productos que a todos los efectos son productos originales de Dahua, pero que tienen una apariencia estética diferente reservada para el mercado en línea (generalmente en términos de logotipo y embalaje). Esto no afecta en modo alguno a la garantía y a las características técnicas del producto, que es siempre genuino de Dahua, ni a las actualizaciones y la funcionalidad.
