This device didn't have any software with it's package, nor links for them.

Windows 7 DirectX can show this device, but i can't find an old  WebCAM code right now.

That device works in Windows 1x, but those apps aren't so good.

That device isn't allowed use by children under 8 years.

Perhaps more to come later.

Hi Timo,

I can't find an old WebCAM code right now.
Did you try some sites like the Internet Archive to find the software?

Actually i want to find an old code from 2014 - 2015,
when i tested COM typelib from quartz.dll

With this code device is available, even WinMCI stopped working with it.
