The TM-CAGE is obvious enough to serve as an effective visual deterrent, but is unobtrusive. Just because it needs to be seen, doesn't mean it needs to be ugly! The enclosure assembles like a puzzle making it deceptively difficult to take apart. The cage conforms as closely as possible to the size of the projector, which allows a more secure design & makes it more attractive. Security is enhanced because the projector can't be maneuvered within the enclosure to squeeze it out of an aperture, & also an attempt to cut the cage would almost certainly damage the projector.
