A security device for electrical or electronic equipment (eg a computer) comprises a sealed unit of dye with rupture lines (9), rechargeable batteries (6), an audible alarm (10), a gas cartridge (7), a gas motor (8), and an electronics module (5). Within the electronics module (5) a plurality of monitoring means are housed which can detect a deviation from normal use of the protected equipment and thus initiate sounding of the alarm and release of the dye over the components of the equipment. The monitoring means may include light, motion and spatial detectors. |
