Do you wanna pay more for the logo LOL?
You can always paint the cameras.
Andy's cameras are Dahua OEM equipment sold under the names Loryta and Empiretech. He also supplies them to the ipcamtalk store.
Some of my cameras I have bought from Andy from his Amazon store come as Dahua cams in Dahua boxes with Dahua logos, and some are not logo'd - I think it depends on how many cameras Andy buys if he gets them with the Dahua Logo or not. But regardless, they are Dahua units. If you get a unit that has Dahua on it, then the camera GUI will say Dahua; otherwise it will simply say IP Camera but looks identical except without the logo. Some of his cameras may come with EmpireTech stamped on them as well.
As long you you buy from the vendor EmpireTech or Loryta on Amazon or his website or via DM, they are Andy cams and Dahua OEM.
His cameras and NVRs are international models and many of them are not available through Dahua USA authorized dealers, but his cameras and NVRs are usually better than what you can find from a USA authorized dealer.
You can update the firmware on Andy's cameras and NVRs from the Dahua website, thus proving they are real Dahua. But you will find that the firmware we get from him is actually better and more recent than what is on the Dahua website because many members here provide feedback to Andy and then Dahua makes modifications to the firmware and sends back to him and then he sends out to his customers. These have been great improvements that Dahua doesn't even update their firmware and add to their website. So many of us are running a newer firmware than those that purchase Dahua cameras through professional installers. Smart IR on the 5442 series is one such improvement. Autotracking on the 49225 and 49425 PTZ is another. We got the next version of AI SMD 3.0 prior to anyone else as well.
Look at the threads here where members are actually testing firmware and improving it for Dahua - find a Dahua dealer with that type of relationship that Andy has with Dahua - I don't think you will find it. Look at the Dahua 4k camera on the 1/1.2" sensor as an example - Dahua provides cameras to Andy to sell before Dahua even made it available and look at all the improvements being made to the firmware from input from customers right here on this site. And the kicker is, we are not Dahua's target market - it is the professional installers...
You do have to be careful with some rebranded cameras purchased from other vendors as they are either fake Dahua cameras or are cameras that are for the Chinese region but have been hacked into English but then are not able to be updated or they will brick. Buying from a reputable source is key to make sure that doesn't happen.
It says you are in the USA, so if you go to an authorized USA Dealer, you will find that you will be spending anywhere from double to five times the amount for a Dahua camera than you can buy from Andy. And as I mentioned, most of the options are not as good as the international selections.
