cctv app

Ziycon

how easy or how hard would it be to write and app to view cctv cameras, i have the hardware and all, and the drivers for the cards, what would be involved in writing the app? say in c++, java or VB??

Should be pretty straightforward, there are plenty of libraries to capture feeds from cameras that have standard Windows drivers, I think the Intel CV libraries or some of MS Research's ones should let you do that kind of thing.

These libraries, where can i get them or are they available through Visual Studio 2003?

Java has known issues if you try capturing from more than one camera ( it can't do it, without some horrible workarounds) , so I would only recommend it for the lightest of projects.

Don't have the exact addresses to hand, Google should turn them up. I think the MS Research one was called the "MS Vision SDK" or some such, far as I recall, it was a fairly low level MFC-based framework for capturing and manipulating camera feeds, used it on a project a few years ago, seem to recall it worked pretty well. Certainly just displaying images from a camera should be easily doable. The OpenCV one is an open source set of vision libraries for higher level stuff, common computer vision operations, didn't use it much, seems quite popular though. And yeah, they should work in VS 2003, I used them in VS 6, will prob work in the newer ones though.

nice one. thanks for the help all!

What video capture cards are you using? Some are provided with APIs specifically to allow for grabbing the data and manipulating light levels.
