Abstract: An image processing device, a camera and a method of encoding a sequence of video images into a single video stream with dynamic bitrate are provided. The sequence of video images is encoded into frames of a base layer of the single video stream using a base layer resolution and a base layer compression level. Video images of the sequence of video images corresponding to respective times before detecting an event trigger are encoded into a first set of frames of an extended layer of the single video stream. The event trigger is detected and upon detecting the event trigger, video images of the sequence of video images corresponding to respective times after detecting the event trigger are encoded into a second set of frames of the extended layer using a higher resolution than the base layer resolution or a lower compression level than the base layer compression level.

Abstract: A method for providing data from a network camera performed in a processing unit of a portable device having a physical communication interface, whereby the portable device has been associated with the network camera. The method comprises: upon detecting a connection to a connected client device at the physical communication interface, establishing a connection to the associated network camera using association data that have been received from the associated network camera when the portable device became associated with the network camera; receiving data from the network camera via the established connection; and transmitting the received data to the connected client device. A portable device and a system of a portable device and a network camera are also disclosed.

Abstract: A movable monitoring device, a method therein and a monitoring system including the movable monitoring device, for configuring at least one preset image capturing position of the movable monitoring device. The method includes arranging the monitoring device in a plurality of image capturing positions, wherein each image capturing position is defined by at least one setting of the monitoring device. For each image capturing position, the method includes capturing an image of at least a part of a scene. Further, the method includes recognizing at least one marker included in a captured image and arranged at a location in the scene. For the captured image including the at least one marker, the method includes storing the image capturing position as the preset image capturing position for the location.
