Home security  

I am wondering how secure do you think your homes are. I have been having problems with people entering my back gate and throwing rocks at my windows and roof. Also trying to break into my back door. I have security lights but they don't seem to stop it. I live in what people call a family neighborhood, but lately there have been break ins and fires set at a nearby school park. Any ideas on how to stop these people or other security type things I can use. Thanks in advance for your help
