Internet Traffic and buying trends 

I would like some market trends information for the number of searches
done on Line over the calendar year.  I want this report or graph to
be specific to Consumer electronics.
And if possible to searches done within the Security camera (CCTV) industries.  

Example: Over the calendar year,  how many keyword searches were done
for the keyword "security camera" (this is the major keyword specific
to the industry I am concerned with)

I need this information broken out in a chart or graph format.  The
graph should depict days or at least  reference weeks.  Helpful would
be marking popular holydays (New years, Easter, 4th Of July, Marmoreal
day, Labor day, Thanks Giving and Christmas.

I am trying to compare the natural market fluctuations  of online
buying with my own fluctuations in my business.  I am finding that
contrary to brick and mortar stores.   Holladay's actually are slower
times for on line business.  I want to be able to look at the graph
and say.  Its the 4 th of July week end, the online buying trends will
probably be off 12%
