rebar

New here. I work in my garage with the door open allot. Motorcycles, tools etc. I don't like to close the door every time I step inside. Nice neighborhood, but I did have a ladder stolen from the side of my home once. Iv been searching for outdoor dummy dome cameras and found a few but they don't state that the dome is glass. I know eventually a plastic dome will turn milky or hazed and give it away. I want to buy the real thing except without the guts. A led isn't necessary. Anyone?
