I'm helping set up a computerized security system for an apartment lobby camera. What I've got set up is a AMD 1.4 GHz (266 MHz FSB) system with 2 80 GB HDs, a Travan Tape Magazine, an ATI Radeon with video-in, and 128 MB DDRAM.
Windows 98 is set up on this computer, but I can get Windows 2000 if need may be. How this system works is that the lobby camera is plugged into the video-in and the programs set up so that it records in 23 hour, 59 minute intervals. These video files are saved across the 2 HDs, and are backed up into tape drives a week later.
With the setup and quality settings, files would probably get pretty big, within the 15-20GB. I placed it in a test run last night, and it appears that the program has stopped saving data after the file has reached 4 GB. I am beginning to think that this is a FAT 32 Filesystem limitation (thinking files in FAT32 cannot be bigger than 4 GB), and am thinking a switch to NTFS would be appropriate.
What think you? Thanks

I think I need lunch. The question is, frozen fries or frozen pizza should I cook?

Never heard of such a thing, but then I can't say I've seen a file larger than about a Gig (pagefile.sys on a NT machine); I take it that you've already played around with quality settings and the expected size is the smallest you can get with useable quality footage?
You might want to consider some sort of motion-detection setup which is available with some webcams. . .

The quality has to be set up to provide maximum space. It's set at 352x240 resolution with a data rate of 1 MB/second. That's the best we can do with resolution and space requirements. It may change depending on our requirements.
A motion activated webcam might be possible. But that is not up to me, I'm not the one designing the security system.

Yes, filesize limits are 2Gb for FAT16 and 4GB for FAT32.
The best choice would be a NTFS with Win2000. This gives you Super Unlimited Filesize Powers.

^^^ NTFS is also more robust (stability, less data fragmentation) and has decent security features. It does have a filesize limit, but you won't reach it with those two drives Posted by Jeff Raven (Member # 20) on :
Ummm... I'm running Win98 and I frequently have 7-8gig files on my computer. No problems.

That must be a disk error. Must be one hell of a missing file chain/fragment/whatever......
