More than 2 webcams on Windows
Well, for the project I envisioned I have MY software and want to attach 4 webcams to the PC. I dug deep down into development only to find out that...
Windows won't work with more than 2 webcams?!
Is there a way around that problem?
Information about my configuration:
- Windows 7 Ultimate (64-bit)
- Relevant applications running in x86 mode
- Canyon or Prestigion 2Mpix web cam (running in 640x480 resolution at 30 FPS)
Each of your webcams produces 35MB/s RGB stream saturating USB2 Consequentially 2Mpx is available only in YUV mode (packaging 32 bits into 6 )
Personally I have no issue running more than 2 cameras from a Linux box, via zoneMinder, but the Windows equivalent: iSpyConnect, states you should be able to run 4 cameras at 320 x 240, on a windows box with 2GB ram, see: http://www.ispyconnect.com/userguide.aspx
I have had the same issue while working on a java image processing project. I was using windows 7 professional 64 bit. I could not capture from more than two video devices when at 640X480 resolution using OpenIMAJ java library.
I was able to add an additional camera when I reduced the resolution to 320X240. I presume this is a hardware limitation on the system as I could not find any other reason for the exception.
Do correct me if I am wrong...
