摘要： A shutter operation state monitoring method performed in a thermal imaging camera includes, controlling a shutter of the thermal imaging camera to be closed, capturing a first thermal image, calculating a correction offset value for the first thermal image, controlling the shutter to be opened, capturing a second thermal image, applying the correction offset value to the second thermal image, measuring a sound with a microphone when controlling the shutter to be closed and/or when controlling the shutter to be opened, determining whether the measured sound matches an operation sound of the shutter, and outputting an alarm indicating malfunction of the shutter if the measured sound does not match the operation sound.

摘要： A door lock control device comprises: a door lock interface for communicating with a door lock; an imaging device; a controller for processing images to be acquired through the imaging device; and a storage medium. The controller determines each of first and second objects in the images as being either authorized or unauthorized depending on whether each of the first and second objects matches authentication data read from the storage medium, and controls the door lock through a door lock interface by referring to a distance between the first and second objects determined from the images when the first object is determined as being authorized and the second object is determined as being unauthorized.

摘要： A system includes a storage device to store a plurality of media segment files captured at a first location, and a management server storing first metadata sets respectively associated with at least one characteristic of the plurality of media segment files. The management server may be configured to: receive a message from a user terminal requesting a media segment file based upon the at least one characteristic; transmit a second metadata set corresponding to the at least one characteristic to the user terminal in response to the request message; and transmit, in response to a request for media segment files associated with the second metadata set, the requested media segment files to the user terminal.

摘要： Provided are a doorbell system and a method of operating the same. The doorbell system includes a doorbell which includes: a camera configured to obtain at least one of an image of a first object in a first region and an image of a second object in a second region closer to the doorbell than the first region; an image processor configured to detect the first object from the image of the first object, and identify the second object from the image of the second object; and an alert generator configured to select and transmit to a user terminal an alert sound or alert sound information corresponding to the identified second object.

摘要： Inverter for an electric compressor comprising an auxiliary voltage supply that supplies a control electronics of the inverter with a DC voltage. The auxiliary voltage supply comprises a series circuit of a linear voltage regulator and a linear pre-regulator. The linear pre-regulator comprises a transistor and is connected to the input terminal of the linear voltage regulator. The linear pre-regulator and/or the linear voltage regulator are advantageously actively cooled by a refrigerant utilized in the electric compressor.

摘要： A media playback apparatus and a method for synchronously reproducing video and audio on a web browser are provided. In the media playback apparatus, audio is buffered to be outputted at a time point at which video is outputted, thereby synchronizing the outputs of video and audio. The media playback apparatus may output the video in synchronization with the audio even when video and audio are decoded by different decoders. Therefore, it is possible to implement a decoder separately from a decoder embedded in a web browser in a non-plug-in environment, thereby reducing the dependency on the codec format of the media.
