A protective guard for the transparent dome of a surveillance camera system deployed in a harsh or dangerous outdoor environment. The guard is a hemispherically shaped metallic unit that covers the dome with a series of longitudinal arcuate ribs originating at the equator of the hemisphere and terminating at an open circle at the pole. The guard may be deployed on a surface-mounted dome having an upward, downward or sideways orientation, or it may be deployed on a heavy-duty dangling pendant enclosure. The pendant embodiment includes weather-resistant features including air insulation around the internal components, and slots that allow for the passage of fluid through the pendant for removal of moisture, cooling and evaporation.
