## Abstract

A method for setting up a monitoring camera includes tilting a camera head of the camera to a tilting position in which an optical axis of the camera substantially coincides with a rotational axis that the camera head is turning around when panning, and in which the camera head is able to capture images through a wide angle lens arranged in a fixed position in relation to a base of the camera. The camera head is turned around the optical axis of the camera and captures images until wide angle images captured through the wide angle lens present the desired orientation. A home position value for a pan motor of the camera is stored, wherein the position value represents the position value for the pan motor when the captured wide angle image presents the desired orientation.

## Claims

### Claim 1

A method for setting up a monitoring camera, the method comprising:
tilting a camera head of the camera to a tilting position in which an optical axis of the camera substantially coincides with a rotational axis that the camera head is turning around when panning, and in which the camera head is able to capture images through a wide angle lens arranged in a fixed position in relation to a base of the camera;
turning, after the tilting, the camera head around the optical axis of the camera and capturing images until wide angle images captured through the wide angle lens present the desired orientation; and
storing a home position value for a pan motor of the camera, wherein the position value represents the position value for the pan motor when the captured wide angle image present the desired orientation.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the camera head when capturing images through the wide angle lens captures overview images of a monitored area.

### Claim 3 (depends on 1)

The method according to claim 1, further comprising presenting on a display the images captured through the wide angle lens as a live presentation of moving imagery in the form of a round wide angle overview.

### Claim 4 (depends on 3)

The method according to claim 3, wherein the turning of the camera head is performed in response to an operator indicating turning of the overview image in an overview interface presented on the display, and wherein the round angle overview presentation is turning accordingly.

### Claim 5 (depends on 1)

The method according to claim 1, further comprising receiving a signal indicating a request for entering wide angle view after a home position has been stored, and in response to receiving the signal indicating a request performing the steps of:
tilting the camera to a tilting position in which an optical axis of the camera substantially coincides with a rotational axis that the camera is turning around when panning; and
turning the camera around the optical axis of the camera until the stored home position of the pan motor of the camera has been reached.
