I am looking for a Video Capture component that can handle 2 cameras simultaneously. Of course two components, handling 2 separate cameras simultaneously will also work, but the operative word is "simultaneously" The application is a machine vision project so speed is also important. Motion detection capabilities will be a bonus. Price is always important. TIA Hendrik.

Try DsPack & its forums at Progdigy.com.I have seen there, many messages regarding using many cameras with the component.The best thing is it is free & is also available for Delphi 2006 from http://82.171.205.59/downloads/DVB/Software/DsPack/dspack_cvs_20060329.zip Venkatesh Back to top Datastead Guest Posted: Mon Apr 24, 2006 11:04 am    Post subject: Re: Video Capture component handling 2 Cameras simultaneousl Hi, You can take a look at TVideoGrabber (commercial), that is able to handle several cameras simultaneously and include motion detection. I suggest you to start from the "Surveillance4Webcams" demo project included in the package, then modify it according to your needs. The home page is http://www.datastead.com/vidgrab/ Michel.

I looked at TVideoGrabber before and it is an excelent product, but I never buy components without source and your source package is to steep for my pocket so I will first look at other possibilities.

Of course it is possible to select 2 different cameras / video sources but the video stream gets distorted, or the one camera half works and the other is almost not responding. I have the same problem with ImageEn. Hendrik "VT Venkatesh" <venks (AT) vsnl (DOT) com> wrote in message news:444c47d2 (AT) newsgroups (DOT) borland.com...

Try TVideoGrabber at http://www.delphicity.com/ It's pricy, but once you see what free gets you, you'll understand why price isn't everything. Back to top Clinton R.

I speak from experience.

It does support multiple cameras, and is free for non commercial purposes. It also has motion detection .

After sending some emails to Fabrizio/support at www.hicomponents.com I solved the problem. The problem was a bandwidth problem on the USB ports. I have multiple ( USB ports on my machine but the two cameras were plugged in to the same internal hub and had to share the video stream. After switching between different combinations of USB ports, I eventually got everything working fine. ImageEn from HiComponents is a great product at a reasonable price (100 EUR -source included) and it can do lots of other things too. Hendrik.
