@Ben321 I think you may be over-optimistic. In much the same way that simply being a US citizen in good standing doesn't mean you can walk into the Oval Office or a nuclear power station anytime you like, I think you'll find that some (much) of the better thermal imaging stuff still requires more than just a chequebook.
(Of course, maybe I'm wrong - the Secret Service might positively encourage random strangers to visit the Oval Office, particularly if they've recently been to see a nuclear facility and are still highly radioactive. I'm not making a political point here, I'd say the same whoever was in power).
There's basically 2 categories of thermal imager, those that can be sold both in the US and overseas without paperwork (except for a few banned countries, such as North Korea which is on a do-not-sell list for such items), and those in the more restricted category that require paperwork for overseas sales but no paperwork to sell to a US address. This hinges entirely on framerate. For <9fps there's no paperwork for overseas sales. For >=9fps there is paperwork for overseas sales. In all cases though, purchasing in the US does not require paperwork.
I know this for a fact, because I already bought such a thermal imager that would have required paperwork for overseas sales. Specifically, I bought a Seek Compact Pro, which has FastFrame (15fps). I know some overseas Pro units are available without FastFrame, but in the US they send you the FastFrame unit. I can verify this because mine says FastFrame in the app when it's plugged in.
The OEM modules with 30fps frame rate from Seek would fit in this same category. Buying one of these would be no harder than buying my Seek Compact Pro was. The only problem seems to be they don't want to sell to individuals, only companies. Even in the inquiry form, where you can ask them about the OEM modules, one of the REQUIRED fields is the name of your company. I have tried filling it in, with "none" as the name of the company. However, I have NEVER heard back from them. They have NEVER sent me an email reply, even to tell me "sorry, we don't sell these modules to individuals, only to companies". They instead have simply NEVER responded. In fact, after a month or so of filling in the contact form once, I did it again. Same result. Over a period of about a year, I think I filled in this contact form about 3 or 4 times, inquiring about their OEM camera cores. NOT ONCE did I EVER get a reply from them. I think this is QUITE RUDE! I would have HOPED this Seek company would have better manners than this! You know that whole customer relations thing is part of being a GOOD BUSINESS. But I guess the IDIOTS running this Seek company don't care about good customer relations, and thus they don't care about being a good business.
