Graber card and camera

Hello all
i need some advice
For a motion traking project i need several camera and graber card as cheap as possible .
I need cameras with a decent picture quality the camera can be black and white , the most important a zoom and i need analog video out from this camera .
I’ m also afraid of the sleep mode of some handycam who can’t be disable.

i need to capture the video from the camera , so i need a grabber card , again as cheap as possible .

For this project , speed is not important, 15fps is enought

If you have any good advice for this hardware please tell me.
