Digital technology now allows us to use
fewer cameras to cover more area with greater detail.
Consider the picture to the right.
The upper left image is the actual digital camera image.
The other three images are all taken from the same digital
image.
A conventional analog camera with the
same camera angle could not produce the details of the other three
pictures. Further it
would take THREE analog cameras to produce the other images.With
proper
system design and camera placement,
morecan be accomplished with fewer cameras using digital
equipment.
