RELATED APPLICATIONS [0001] This application is a continuation of prior application Ser. No. 10/821,659, filed Apr. 9, 2004, entitled SECURE MOUNTING SYSTEM FOR OVERHEAD MOUNTED PROJECTOR, which claims benefit of Provisional Application No. 60/462,391, filed Apr. 11, 2003, entitled SECURE MOUNTING SYSTEM FOR OVERHEAD MOUNTED PROJECTOR, each of the aforementioned applications being hereby fully incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to mounting systems for visual projectors, and more specifically, to tamper resistant mounting systems for projectors. BACKGROUND OF THE INVENTION [0003] Visual projection systems are commonly used for displaying and presenting visual information to groups of people. Such visual projection systems typically include a projector unit and a projection screen. [0004] In spaces such as classrooms, conference rooms, and public assembly halls, where the space is often used for presentations, it is common that the projector unit be installed as a more or less permanent fixture in the space. Often, the projector will be suspended from an overhead structure, such as a building floor/ceiling assembly or roof, in order to give the projector an unobstructed projection path and to protect it from damage by inadvertent contact. It is generally desirable that the mount be adjustably positionable over a wide range of positions to enable proper aiming and focusing of the projector. [0005] Projectors, particularly LCD, CRT, and DRP projectors designed for frequent use in a setting such as described above are quite expensive. In addition, the spaces where the projector is installed may be unsecured for periods of time or left unattended. Consequently, a problem is that projector units are attractive targets for theft, vandalism and other tampering. [0006] Another problem is that in some multi-use spaces, such as gymnasiums, the projector unit can be exposed to the possibility of unintentional or intentional contact by objects such as balls or other similar flying objects. In other multi-use spaces such as hotel conference facilities, the projector unit may be subject to contact by ladders, maintenance person lifts and the like during set-up and take-down of exhibits and booths. [0007] What is needed in the industry is an easy-to-use adjustable ceiling mounted projector mounting system that substantially alleviates these problems. SUMMARY OF THE INVENTION [0008] The present invention is an adjustable tamper-resistant overhead mounting system for a an LCD, CRT or DCP projector that addresses the aforementioned need in the industry. The adjustable mount bracket of the present invention includes brackets attachable to the projector and a suspension member attached to an overhead structure. At least one tamper resistant fastener is used at each connection of the brackets, the projector and the suspension member, to deter theft and tampering. The brackets enable inverted mounting of the projector from the ceiling structure of a space. The arrangement of the brackets may enable easy adjustable positioning of the projector about pitch, roll and yaw axes. The projector may also be enclosed in an enclosure system to protect against contact by foreign objects. The enclosure is adapted to be installable without removing the projector or otherwise disturbing the mounting system. [0009] A tamper resistant mounting system for adjustably attaching a visual projection device to a suspension member that is fixedly attached to an overhead structure includes a device interface bracket attachable to the projection device with at least one tamper resistant fastener. The device interface bracket is operably coupled to a suspension member interface portion. The suspension member interface portion is attachable to the suspension member with at least one tamper resistant fastener and is secured to the device interface bracket with at least one tamper resistant fastener. [0010] The mounting system may further include an enclosure adapted to enclose the visual projection device. The enclosure includes an integral surround portion having a top, a bottom, a pair of opposing sides, and a pair of open ends. A pair of end caps is provided to fit over and close the open ends. Each of the end caps is secured to the surround portion with at least one tamper resistant fastener, and enclosure is secured to the tamper resistant mounting system with at least one tamper resistant fastener. At least one lock and an elongate locking bar may be provided to secure the end caps on the enclosure.
