A surveillance camera assembly housing (28) is releasably locked to a base (24) for the housing. The base is installed in a ceiling or at another location remote from ground level. A removal tool (22) provided at the end of a pole (136) has fingers (36) which are inserted into apertures in the assembly housing. The tool engages the assembly housing by means of the fingers, while also being operated to release a mechanism which secures the housing to the base. The housing, now secured to the tool, is removed from the base and brought to ground level. In this way, removal of the surveillance camera is accomplished without resort to ladders or scaffolding.
