I am looking for some information on the major manufacturers in the
field of Home/Personal Security.  More specifically, I would like a
list of company names as well as contact information (website and
phone number) for the major producers of pepperspray, stun guns, home
surveilence units, and other personal security products.  The more
detailed the information, the better, and if there is any indication
on how large these companies are - I would really appreciate knowing. 
Any market data you could also find would be great as well -
especially pertaining to market share.  Thanks!
