A surveillance system controller comprising a housing, a first control module and a second control module. The first control module is located in a first location in the housing, and it is rotatable around a first axis so that the first control module can be rotated to a first angular position. The second control module is located in a second location in the housing, and it is rotatable around a second axis so that the second control module can be rotated to a second angular position independent of the first angular position. |
