NTSC conposite to USB video monitor

[Opcom]

I got hold of a couple USB touch screen LCD monitors that work on 12 Volts DC. These all work plug-n-play (apparently no special driver needed -or driver came with Windows). Works great when plugged into a windows 10 computer's USB port, and look really good, for a 7" monitor, with 1024x600? resolution.

That being said, these are some OEM or generic brand, no name on them. But who cares, they were free.

The thing is, I want to provide a small monitor to work with a FLIR thermal camera which has an old style analog NTSC video output.

I don't care about audio or the touch feature. (touch or the included stylus isn't working with windows, perhaps a driver is needed for Touch.)

The goal is to display the image from the camera, and build the camera, screen, and battery into a simple hand-held device with which I can look into equipment to find the hot spots, etc. Not worried about resolution as the FLIR is just 32x32. But it's enough for my purpose.

Having said this, I don't find an adapter or little box that would take NTSC analog video in, and feed a monitor's USB input. The monitor has a USB Type A Male connector. The adapter needs to have a USB Type A female adapter (socket) same as a PC's USB socket.

I can find boxes all day for a few $ that take NTSC analog video in, and have a male USB Type A connector to feed a Computer's female USB input socket. But this is not what I'm looking for.

Someone suggested that I try an analog NTSC-to-HDMI adapter, and then plug an HDMI-to-USB adapter into that, to feed the monitor. They didn't know if that sort of kluge was going to work or not.

I understand there is a lot of handshaking going on where USB and HDMI are concerned due to drivers and resolutions and I have no idea either if that will work or not.
