Hikvision “OEM” is a product with the Hikvision name on it, and Hikvision model number. The “generic” market, is that same product, (still manufactured by Hikvision) but with a different brand name on it, and a generic model number. Some companies even create their own model number. The supplier I use has their own model numbers, but they gave me a spreadsheet that shows their model number, the generic model number, and the official Hik model number. It’s handy to decipher exactly what I have. Also, the generic market is usually cheaper and offers better service
