Put the bad guys on notice. They are being watched. Add a dummy camera or two (from our Ebay store) to complete the setup. Put the sign on your door, on your back yard gate or display it in a window where it is sure to be seen. This is a simple, inexpensive deterrent against intrusion. Measures 9" x 12" with red lettering for high visibility. Weather resistant plastic. Not for use in intense direct sunlight.
