This is a good question, whether or not Huisun is the original manufacturer. Having work for a hardware manufacturer (printers) for over twenty years, the OEM side of the business was always a big part of our sales. We would sell our printers to other manufacturers and put their name on our products. We would also buy printers from other companies and put our name on them. Generally speaking, whoever had the lowest price was probably the original manufacturer of the product, but this wasn't always the case when you deal with very large companies and large order quantities. A few days ago I got the following comment on my YouTube channel for my Huisun Mini PTZ Camera Demo video. Now half the comments on YouTube are from trolls, but I thought I paste this comment here since this person might seem to know what he was talking about. Not sure if the person commenting is from the manufacturer or just another retail sales person.

Pretty nice demo and beautiful scenery, honestly I recorded several demo but not as good as yours... Next time my client ask me for demo video, maybe I can send him this link lol. And about the history of this camera, we start sale since April, have no bad feedback about its PTZ performance yet. Someone may doubt its durability, but we know it can last long time because we have tested it since we start developed it 2 years ago."
