A surveillance camera housing (20) contains a crown plate (30) with voids and radially extending flanges (32) which engage corresponding radially extending flanges (28) and voids in a mounting cap (24). A radial gasket (42) is disposed upon the crown plate (30) and electrical connectors (36) are disposed within the radial gasket (42). In operation, the flanges (32) of the crown plate (30) are placed within the voids of the mounting cap (24) and the flanges (28) of the mounting cap (24) are placed in the voids of the crown plate (30). When the housing (20) is further lifted vertically a horizontal plane defined by the crown plate flanges rises above a horizontal plane defined by the mounting cap flanges (28). The housing (20) is then rotated so that the crown plate flanges (32) rest upon the mounting cap flanges (28).
