Abstract:
1. A security surveillance system comprising: a support; a surveillance device mounted on the support; and a cover assembly, the cover assembly comprising a shield member with a convex shape having an outer periphery and a flange that extends around and outwardly from the periphery of the convex shape, the cover assembly changeable selectively between: a) an access state wherein at least a first operating state of the surveillance device can be changed by an operator at, or in the vicinity of, the surveillance device; and b) an operative state wherein the cover assembly blocks access by an operator as would permit changing of the first operating state by an operator at or in the vicinity of the surveillance device, the cover assembly having a first component and the support having a second component, the first component residing substantially fully outside of the periphery of the convex shape, the first and second components mutually attracted to each other and located so that an operator can move at least a part of the cover assembly with the cover assembly in the access state in: a) a first path in a first direction as an incident of which the cover assembly is caused to be placed in the operative state and maintained in the operative state by a first attractive force between the first and second components; and b) the first path in a direction opposite to the first direction with the cover assembly in the operative state, at least initially under a force greater than the first force to thereby change the cover assembly from the operative state into the access state.
