A Need For surveillance Cameras - A Good Business Idea For Sales

I have a cat and have put up a meg shift chicken wire fence along a wooden railing under a porch in our home.  I say meg shift because that's what it is, I am currently living at a house in which I don't own so I couldn't enclose the porch correctly.  I wanted a place where my cat could go out on her own and just enjoy the great outdoors any time she wanted.  Because this fence is not secure, she could get out if she really wanted to, say when she sees a bird or something, so I have to constantly monitor how she's doing by walking to the porch and looking to see she's OK.  If I had a camera out there, I wouldn't need to do this, I could have a window up on my computer as I'm writing this post and see her, that would be a great thing.  So surveillance cameras and equipment are need, I am seeing many needs for them and will have to research wholesalers and a way to sell them online.
