It wasn't an ebay purchase.
Amazon. Came with a little disk but the instructions sound like they are for a different product. A wireless camera receiver?
Anyway I have the EasyCAP002 which is the 4 channel plus audio usb device.
I don't think the drivers are installing properly though.
The software application on the little disk is Jin Li Tong, Multiviewer
But I can't get it to find the camera when I plug it into any of the inputs.
