Abstract: A method calibrates a camera having image sensor having a center position. An image view projected onto the image sensor by a lens is captured. At least one image view boundary of the captured image view is detected. A projection center position corresponding to a center of the projected image view is determined in at least one dimension. Offset between the projection center position and a sensor center position is determined, defined in at least one dimension, corresponding to the center of the image sensor capturing the projected image view. The image sensor is moved in relation to the lens based on the offset in order to arrive at a substantially zero offset in at least one dimension between the center of image sensor and the center of the projected image view.

Abstract: A method is provided for switching operation of a monitoring system from a first monitoring mode to a second monitoring mode. An overview image is presented when the monitoring system is in a first monitoring mode. A direction signal is received from a control means when the monitoring system is in the first monitoring mode. A camera is directed in an absolute direction indicated by the direction signal in accordance with a first camera control scheme. The monitoring system enters into a second monitoring mode in response to receiving the direction signal presenting a detailed image view captured by the camera when directed in the direction indicated by the direction signal. When in the second monitoring mode, a camera head of the camera is moved in response to control signals from the control means in accordance with a second control scheme.
