A method and mobile unit facilitate installation of a surveillance camera for monitoring an object of interest in a scene. The surveillance camera acquires a zoomed out image of the scene. The zoomed out image is displayed in a display wherein the zoomed out image has a zoomed out center point. An indicator overlaid on the displayed zoomed out image is displayed in the display, wherein the indicator and the zoomed out center point are displaced in relation to each other by a deviation. The indicator indicates the position of a zoomed in center point of a zoomed in image of the scene. The surveillance camera is directed so that the position of the object of interest and the indicator coincide so that the object of interest is included in a zoomed in image of the scene.
