The MS-4000 ShootingStar Proximity Reader is designed for areas where crime and vandalism are a constant threat to the access control system's card readers. The outside housing is made of stainless steel and is beveled such that it is nearly impossible to get sufficient leverage to pry it off a wall or mullion. The portion of the face of the reader that covers the electronics consists of a material that is many layers of interwoven fiberglass (UL 752 listed for bulletproof integrity). The reader can withstand 9mm bullets a "point-blank" firing range and will not be burned by common cigarette lighters, both which are typical sources of vandalism.
