La empresa asiática, fundada en 2001, debe su reputación a la excelente calidad de sus productos en términos de rendimiento y capacidad. La gama de productos de Dahua abarca desde los sistemas clásicos de CCTV hasta los sistemas de seguridad más complejos y articulados: no sólo la videovigilancia, sino también el control de acceso, los sistemas de videoportería, los productos de detección térmica y mucho más. 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. Las cifras hablan por sí mismas: desde 2016 hasta hoy Dahua ha registrado más de 800 patentes con su propia marca. Actualmente Dahua puede presumir de estar entre los 10 primeros líderes mundiales en el mundo de la seguridad. Este año Dahua fue premiado con el 2º puesto en el ranking "2019 TOP SECURITY 50".

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.
