I think security and motion sensor lights will better serve you. My experience with cameras has been that you will be able to watch people getting into your stuff. Getting law enforcement to do anything about it may be an effort in futility. You may even run into some legal problems of your own if your cams are recording public streets and sidewalks, particularly if minors are recorded. A Pitt bull will keep the hood rats out of your yard, but that opens yourself to other issues.
Good luck
