Produkte, die vollständig original Dahua-Produkte sind, aber ein anderes ästhetisches Erscheinungsbild haben, das dem Online-Markt vorbehalten ist (im Allgemeinen in Bezug auf Logo und Verpackung). Dies beeinträchtigt in keiner Weise die Garantie und die technischen Eigenschaften des Produkts, das immer ein Original Dahua ist, noch irgendwelche Aktualisierungen und Funktionalitäten.
