How to Use IP Night Vision Camera as USB Webcam on Linux for Computer Vision?

Hello everyone. My problem is that I need to use a usb camera (webcam) in an artificial vision project in LINUX and I can not use an IP camera. So far one could think of using a usb camera directly but I can not find a usb camera with the features that my project requires.
It is night vision and the cameras that meet this requirement I have only found in the market as the typical IP video surveillance cameras that bring a system of infrared LEDs around the lens to be able to visualize during the dark a whole room without problem.
I tried to modify several usb cameras to be able to integrate a system of infrared removing the IR filter they bring in the lens but none has given me the feature of being able to capture in full darkness even if it detects the infrared light. (not sensitive)
So the only possibility I have left is to use one that works under those conditions (IP video surveillance camera) but I need it to be via USB and not IP.
Is there any way or do I have it more than cheesy?
PS: I have not been able to find USB cameras capable of seeing in the dark, not yet because they are not manufactured and if the IP.
Thanks!

It sounds to me that you need some kind of USB to ethernet converter.  Such thing do exist but I have no idea if they will work in your case. Just google  "usb to ethernet converter"Here is one that I came up with https://www.amazon.ca/gp/product/B00BBD7NFU?gclid=Cj0KCQjwvabPBRD5ARIsAIwFXBliNWOD6A3y52znKArP96OqX20U2Zk0eXsZgrJU95J5-Djr0mqLqa8aAloXEALw_wcB
It claims This lightweight USB to network adapter is a perfect accessory for adding a standard RJ45 port to your Ultrabook, notebook, or Macbook Air for file transferring, video conferencing, gaming, and HD video streamingGood luck!

Hi Ignacio-I wonder what would happen if you got an IP camera that has WiFi connectivity and paired it with one of those little WiFi>USB dongles? Another option might be to get a surveillance camera that has an analog output.  Any chance that the computer you are using has an analog video input?  If not, there are plenty of analog (NTSC) to USB capture devices available.I'll bet there is a USB camera that has night vision functionality, but I haven't found it yet.  I'll keep looking.

I think you're going to have problems here..... have you thought about getting some IR LEDs (10 or so) and mounting them round a USB camera?    Most cameras are quite good in IR (thought you will get a monochrome pic) and you might find you get usable results.  Cameras won't detect the IR emitted by objects like true night vision cameras do, they need illumination.
I picked up some vehicle reversing cameras the other day and they work quite well, they have built in IR LEDs and can see things up to about 30 feet away in the dark.  However they are standard PAL AV output, probably no use for you,  Also resolution 320 lines only, though that's adequate for reversing.  If you think you could use one let me know.

All the USB cameras I have used together with a module of 54 infrared leds are not able to see in the dark with this last module.I wish I could find a USB camera that next to the module of infrared leds can see a distance of 1 meter (I don't need more distance) but I have not been able to do it.I read on the internet that removing the infrared filter to usb cameras can be achieved but none of it has a built-in.

Cio...I will check further on this....I have a Logitech webcam, I will bring one of my PAL cameras with IR and just use it for the IR and see what results I get from the Logitech camera,  and advise.  

FYI- I just noticed on eBay you can get night vision backup cameras (for automobiles) for under $20. Most are analog but I did see one that was USB.  Be careful though- some of the backup cameras have the image reversed horizontally.-Rick
