La fiabilidad, la tecnología de punta y los precios competitivos que ofrece Dahua son sólo algunas de las razones por las que Setik siempre ha elegido distribuir la marca. Dahua es desde hace años un sólido punto de referencia en el mercado internacional de los circuitos cerrados de televisión, gracias a las enormes inversiones que cada año se dedican a la investigación y el desarrollo.

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.
