    • A method for controlling privacy mask display in a monitoring camera is provided to properly move/display a privacy mask even when the monitoring camera is panned or tilted at high speed by a pan or a tilter in a state that the privacy mask is displayed within a monitoring video frame, thereby preventing a specific subject from being exposed. A method for controlling privacy mask display in a monitoring camera comprises the following steps of: confirming a panning or tilting velocity when a panning or tilting operation is performed in a state that the monitoring camera is mounted on and connected to a pan/tilter(S12,S16); searching and reading a pan location compensation value or a tilt location compensation value corresponding to the confirmed panning or tilting velocity(S13,S17); calculating pseudo pan location information or pseudo tilt location information by adding the read pan or tilt location compensation value to current pan location information or tilt location information(S14,S18); and transmitting the calculated pseudo pan or tilt location information as information for variably controlling a privacy mask display location of the monitoring camera(S19).
