Hi Since you suggested jpeg picture compression I am assuming you are saving the pictures as bitmaps (bmp) then I should definitly save them as jpeg, it is possible to get 100:1 compression on colour pictures.
With the picture toolkit that comes with my 6.1pro I was able to compress a 5,626kb 24bit 1600x1200 bitmap picture to 66kb! And the picture quality wasn't too bad.

Blasberg [mailto:[EMAIL PROTECTED] Sent: Wednesday, 9 June 2004 1:40 a.m. To: [EMAIL PROTECTED] Subject: Video surveillance A customer of mine has a process which takes about 40 seconds and operates on parts being manufactured. 15 seconds to get the part into position, 10 seconds to operate on it and 15 seconds to return the part. He wants to have color pictures taken for surveillance only - just to see if the part was mishandled and such. That is, there's absolutely no requirement for any kind of image analysis. He initially thought to use a PCI-1411 card with a standard video camera (PAL in our case) and snap pictures (2 every second while the part is in transport and 4 per second during the process). This results in LOTS of pictures which requires LOTS of disk space and archiving to DVD (about 2 days of pictures and data per DVD). They do about 10,000 parts each month. My question is: does anyone have a better idea? Just thought I'd throw this out to the multitude of brilliant (not to mention creative) people on this list to see if we've missed something. One more thing: the pictures would only be displayed off-line together with a part's data whenever the user wants. I suspect that each picture would have to be compressed (JPEG?) to conserve space.
