    Abstract: 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.

    Abstract: 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.

    Abstract: A camera assembly includes a motor configured to generate a driving power; a motor shaft that extends from the motor, such as to define a first axis, and is configured to rotate by the driving power of the motor; a pulley configured to rotate on a second axis, that is spaced from the first axis, according to rotation of the motor shaft; a belt configured to couple the motor shaft and the pulley, and convert the rotation of the motor shaft to rotation of the pulley, and tension of the belt applies a force to the motor shaft in a direction towards the second axis; a camera module configured to be mounted on the pulley and rotate together with the pulley; and an elastic body configured to apply a biasing force to the motor shaft such as to bias the motor shaft in a direction away from the second axis.

    Abstract: A real-time video streaming method between a server and a client according to a real-time transport protocol (RTP)/real-time streaming protocol (RTSP) standard protocol, including transmitting a DESCRIBE command including a Require header from a client to a server, wherein the client and the server support the Require header, receiving session description protocol (SDP) information from the server in response to the DESCRIBE command, receiving, at the client, a video from the server according to the RTP/RTSP standard protocol, in response to an encoding attribute of the video transmitted from the server to the client being changed, describing a changed encoding attribute in an RTP extension header of an RTP packet when the RTP packet is first transmitted in an RTP payload type determined according to the changed encoding attribute, and changing, at the client, a decoding setup based on the changed encoding attribute in the RTP extension header.
