A method of placing a surveillance camera in a known reference orientation as a result of panning and tilting movements includes coupling the camera to a fixed structure such that the camera may perform the panning movements about a first axis and may perform the tilting movements about a plurality of second axes. The micropolarizer is composed of a plurality of first polarizing regions having a first polarizing direction and a plurality of second polarizing regions having a second polarizing direction perpendicular to the first polarizing direction. \u201d A hose provides access to the VPN through an access point which may be a node of the network, for example.
