Wireless security camera's?

[livwire68]

Anyone have any experience with them. I am looking at some of the $100 models that are wireless and can be viewed from any internet source. We had some people move in a few weeks ago and there have been some problems arise. My Son had his bike stolen from inside the garage. There are about 8 people living in the house from young kids to older kids and no one seems to be over 18. The police have been there twice, the county multiple times including a truency officer. We have documented any problem with the HOA (they are just renting) I am just looking for a way to further protect my family and anything I have worked hard to own. The camera's also allow me to get video documentation if there are any future problems.
