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.

Method for calibrating a camera

A method for determining a position for a stationary device with assistance provided by a mobile device is disclosed. The method comprises receiving, by a microphone of the stationary device, an activation sound; in response to the received activation sound, sending a request for position data addressed to the mobile device; receiving position data from the mobile device; and storing the position data as being the position of the stationary device. A method for assisting, by a mobile device, in determining a position for a stationary device is also disclosed. A stationary device and a system for determining a position for the stationary device are also disclosed.

Method, stationary device, and system for determining a position

A method for improving audio experience for a user of an audio device is provided. The method includes establishing a communication channel between the audio device and a remote client; detecting a peripheral audio device in the vicinity of the audio device; establishing a temporary communication channel between the peripheral audio device and the remote client; and transferring, via the temporary communication channel, audio data between the peripheral audio device and the remote client.

Method for improving audio experience for a user of an audio device

A method for adjusting an audio zone sound image in an audio system () comprising a plurality of audio zones (A,B,A,B,C,D,A,B,C) is disclosed. Each audio zone has one or more loudspeakers () located therein. The method comprises recording () a sound image of a controlling audio zone; transmitting () audio data corresponding to the recorded sound image to a controller; evaluating () the transmitted audio data; selecting () an adjusting audio zone, wherein the adjusting audio zone is other than the controlling audio zone; and adjusting () an adjusting loudspeaker such that the sound image of the controlling audio zone is changed. An audio system () and a controlling loudspeaker are also disclosed.

Method, device and system for controlling a sound image in an audio zone

A method for audio calibration of an audio device is provided. The method comprises: registering, by a microphone, a representation of an audio signal; processing, by a data processing unit, the registered representation of the audio signal into feedback image data; displaying on a display, the feedback image data; capturing, by a camera, the feedback image data displayed on the display; altering a setting affecting audio of the audio device based on the feedback image data captured by the camera. A system for audio calibration of an audio device is further provided.

Method and system for audio calibration of an audio device

Described is a method for registering and executing instructions in a video capturing device and to a door station. The method comprises receiving at a video capturing device a signal(s) representing a first input made using an authorized device, generating a graphical representation of the received signal(s), superimposing the graphical representation onto video captured by the video capturing device and streamed to the authorized device, receiving at the video capturing device, after the signal(s) representing an input made at the authorized device have been received and graphical representations have been generated and superimposed onto video captured by the video capturing device and streamed to the authorized device, a concluding signal representing a concluding input made using the authorized device, translating, in response to said concluding input, the received signal(s) into an instruction executable by the image capturing device, and executing the instruction resulting from the translation of the signal(s).

Method and system for controlling a device

A method relates to distributing user credentials in a distributed physical access control system, and more generally to distributing user credentials in a distributed system. A method may include storing a user credential database (DB), a first transformed credential DB and a second transformed credential DB for authenticating users to access a first and a second service provided by the device. The method may include generating the first transformed credential DB and the second transformed credential DB based on the user credential DB and comparing a credential received from a user to the first or the second transformed credential DB to determine whether to grant access to the first or the second service. The method may include distributing the user credential DB to a plurality of other devices connected in a network for the other devices to generate transformed credential DBs for authenticating users to access services.

Distribution of user credentials

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.
