Most of Hikvision products sold in the US are the non-branded OEM versions. The non-branded product is the exact same item, but the Hikvision logo is removed and they use a different OEM part # on the sticker. We are able to get non-branded versions at lower costs and therefore offer our customers lower prices. The product that you order is manufactured by Hikvision and carries their 3 year warranty.
