A device and method for managing metadata associated with an object detected in an image, where the object corresponds to an area of the image are disclosed. A metadata item associated with the object is obtained, where the metadata item includes an identification of the area, and a quantitative level of an image data characteristic of the area or of the area as encoded is determined. A condition in relation to the determined quantitative level of the image data characteristic is evaluated, and on condition that the condition is fulfilled, reducing or discarding the metadata item. In an alternative, a level of compression of the area as encoded is determined, and it is determined if the level of compression is higher than a compression threshold. On condition that the level of compression is higher than the compression threshold, the metadata item is reduced or discarded.

Methods for configuring a monitoring device to communicate with a service server are provided. The method includes the monitoring device sending a message including a monitoring device identifier used by a control server to identify the service server associated with the monitoring device, receiving one or more service server addresses associated with the identified service sever from the control server, and establishing a service connection between the monitoring device and the identified service server using the one or more addresses received from the control server. A control server adapted to configure a monitoring device in a monitoring system and a method for configuring the control server are also provided.

Monitoring system and method for connecting a monitoring device to a service server

Methods for configuring a monitoring device to communicate with a service server are provided. The method includes the monitoring device sending a message including a code used for authentication of the monitoring device to a control server, receiving one or more addresses of a service server associated with the monitoring device from the control server in response to the monitoring device being authenticated by the control server, storing the one or more addresses retrieved by the control server, and establishing a connection between the monitoring device and the service server using at least one of the one or more addresses received from the control server.

A method and system for composing a video of a course of actions along a track in an area monitored by a plurality of video cameras. A first sequence of user inputs defining the track is received. Each user input in the first sequence is associated with a time stamp and is received as an indication of a position in a map of the area being monitored. For each user input in the first sequence, video recordings from those that have a field-of-view covering the position indicated by the user input are collected. The collected video recordings are recorded in a time period starting at the time stamp associated with the user input and ending at a time stamp associated with a next user input in the first sequence or when an indication to stop the collecting is received. A video material is then composed from the collected video recordings.

A method for carrying out a health check of at least two cameras comprising the steps of initiating a health check process and checking, in response to the initiating step, for motion events stored in a database storing motion events, for each of the two cameras. If the checking for motion events indicates that a motion event has been stored in the database for one of the at least two cameras, then the method further comprises the steps of selecting a motion event found when checking for motion events stored in the database and retrieving a video clip corresponding to the selected motion event, captured by the one of the at least two cameras. The method further comprises the step of displaying the retrieved video clip together with a corresponding camera identification for evaluation.

Methods and techniques for configuring a monitoring device to communicate with a service server. The method includes sending, by the monitoring device to a control server, an initial connection message, authenticating, by the control server, the monitoring device using the initial connection message, in response to authenticating the monitoring device, sending, by the control server, a list of one or more addresses to the monitoring device, and establishing, by the monitoring device, a service connection between the monitoring device and a service server using the list of one or more addresses received from the control server.

A control device for controlling an electronic device over a communication network; the electronic device comprises data storage having control parameters and associated access levels which control operation of the electronic device; circuitry which generates a control setup message including the control parameters and access levels; and a network interface for sending the control setup message. The control device comprises: circuitry for determining an access level of a user logged in to the control device; a network interface for receiving the control setup message; control interface setup circuitry for generating a set of control parameters, extract control parameters having an access level equal to or lower than the access level of the user logged in to the control device; and a graphic generating circuitry for generating a graphical control interface comprising control graphics enabling control of different states of operation of the electronic device corresponding to the extracted control parameters.

A method according to the invention for connecting a monitoring device to a service server may comprise retrieving an address relating to a control server from a memory of the monitoring device, sending a connection message from the monitoring device to the address relating to a control server in response to a connecting event, extracting, at the control server, an identifier from the communication between the monitoring device and the control server, identifying, at the control server, a service server associated with the extracted identifier, sending an address relating to the identified service server from the control server to the monitoring device, sending a connection message from the monitoring device to the identified service server in response to the receipt of the address related to the identified service server, establishing a service connection between the monitoring device and the identified server.

A network connector device and a method for making image information sent through a first digital network accessible by a second digital network. A first and a second network connector are arranged to pass on digital network traffic, a network traffic buffer buffers the digital network traffic, an image session identifier identifies a network session from the buffered digital network traffic, containing image information. An image session tracker tracks the identified network session containing image information, an image extractor extracts image information from the identified network session containing image information, and an image information buffer buffers the extracted image information. An image information arranger arranges the image information from the image information buffer into at least one image sequence of related images, and a server makes accessible the at least one image sequence via a third network connector.
