There is a good amount of crime going on in our neighborhood. Most of the time people doing the crime get there with their cars. Unfortunately, the cameras mounted on our home are not in an ideal position to scan license plates of cars driving down the street. Hence, I am considering installing a cam in the front yard that scans each car passing by (not that I care to watch the cam unless a neighbor was burglarized). So I want to hide the cam, probably behind some plant. At the same time I want to let people know (they are not just down the street so can't just send a mailer) that we are not observing them while we are still providing some protection for the neighborhood. Any input how to handle this balance between surveillance and protection is appreciated.
