displaying live video on monitor

[Socrates]

I am trying to capture human motion on the pc monitor with a view to
taking sequential shots of the desktop for cctv purposes. Hypersnap
from www.hyperionics.com allows me to take a snapshot of the preview
screen every second and saves the images as jpgs on the hard drive.

The only problem I am tying to overcome is how to display the camera
scene from the digital camera without any blur on the monitor. If for
example I move my arm in front of the camera I see a slight
blur/ghosting effect on the screen and the movement on the monitor
actually lags behind the motion.

I don't think it is simply a matter of getting the most expensive
graphics card, as that does not appear to solve the problem. I use a
Radeon 7000 graphics card which may not be the best but it seems ok
with a Pentium 4 2gh processor and windows xp professional.

So what is the best way of displaying motion in the camera scene as
clear as possible on the pc monitor? If we could solve that problem
many more people around the world would simply configure their cctv
cameras to display a clear image of the camera scene on the monitor and
then snap the image using a screen snap utility.

Saving sequential jpg images on the pc hard drive would be much better
than saving and storing compressed video clips, but all this depends on
being able to display motion clearly on the monitor so that clear
sequential snapshots of the capture window can be taken and suspects
more easily identified even if they are in movement.

How about a totally different (and I hope significantly easier)
approach?
Simple use a digital camera in movie mode to capture the motion, load it
into the
computer & use Microsoft Movie Maker (MMM) to copy any still you desire?
Honestly, MMM comes with WinXP, is incredibly easy to use, and will
provide you with as many sequential snaps as you desire. And the only
blurring
will be from moving the camera too quickly, or having the subject move too
quickly. If those are problems you may have to step up to a better camera.

For CCTV purposes one must capture for 24 x 7 and then not need to look at the set-up for month month at a time unless an event has occurred.

Capturing in movie mode would not therefore provide a solution.>
