At some point you may decide that one shot every 20/30s isn't enough, so
having a fast reliable network will become more and more important, as
you add cameras and start increasing frame-rates.  Depending on the size
of picture you want to store (once again think about Frank's other list
items -- image resolution & quality) you can saturate a low throughput
network.  If you're doing multiple cameras, or having multiple pictures
coming into the server per second, post-processing of the images on the
server end, you will end up with a CPU bottleneck.

Look at the low-light performance of your cameras also.  You don't want
to record a blur ... you want a useful picture of a person that you can
show to the authorities.  Make sure the target area is well-lit.
