I have a question regarding the usage of nanny cameras at one's own
home, to monitor nannies while away at work (or elsewhere).  I am
looking to hire a live-in nanny for my child, and have been thinking
about installing multiple cameras (in different areas of the home), to
monitor the care provided to my child while I am away.  I have looked
at quite a few sites that sell these nanny cameras and am looking for
specific/consolidated answer based on someone's personal
experience/knowledge regarding these different options available
(rather than directing me to different sites).  Here it goes:

-  First and foremost is it legal to use these cameras without the
consent/knowledge of the nanny.  I guess the answer would be state
dependent and I am looking for an answer specfic to Illinois.

-  What is the best type/recommendation of wireless camera(s)
avaialble that would provide a good resolution (model details etc.). 
Does a color camera give you better images over black & white cameras?
 What is the distance it can capture images at?  Any maintenance etc.
issues that someone has personally experienced/known about the above
model(s)?  What is the best deal in terms of cost/value ratio for
these different model(s)?

-  How do I consolidate all these multiple cameras/images into one
desktop monitor.   I want the ability to log on to this desktop from
anywhere and be able to view these images from work.  I want the
details of how I can set this process up.  Also is viewing over the
internet an option?  Lastly I want to store/save these images (from
all the cameras) on the desktop (and have the ability to delete them
when I want).  How can I enable this on the desktop?  This is very
important (store/save and retrieve/delete later feature).

A quick response is greatly appreciated!!
