NTSC conposite to USB video monitor
 

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.

I suspect no such product exists. USB A is a data transfer interface standard for computers (and sometimes for power transfer)... Every devicethat isn't computer that sends and or recieves data or video over USB is going to have as its core design assumption that 'the data/video link has a computer at one end of the USB cable'.

The easiest solution is probably going to be a raspberry pie computer, or a mini PC that automatically boots on powerup and auto runs an app to display the video to its main monitor which will be your 7" unit.

Otherwise your probably designing your composite video to USB adapter from scratch and doing much research and programming.

Thank you and I will have to agree with your points as nothing's turned up. So, I'll have to find a NTSC composite monitor. The project isn't worth the resources including a separate PC to make that monitor work the way I want.

On the other hand I have used a raspberry pi as a tiny Linux PC a decade ago, though it had HDMI for video, and maybe one of those monitors would work with a usb port on a pi of the types offered today. I prefer a human-size keyboard to a touch screen anyway, so a mini keyboard with a trackball might fix that up.
