Abstract: According to one aspect of the present invention, since a tilt motor is provided in a common gimbal assembly and the common gimbal assembly is rotationally driven about a tilt axis by rotational driving of a tilt motor, the common gimbal assembly can be compatibly applied to any type of surveillance camera.

Abstract: The proposed invention relates to a technology for a system including a camera device that reliably manages an original of image data at an initial generation time point at which the image data is generated by the camera device, wherein the camera device includes a first authentication block information generation commands set, and the first authentication block information generation commands set generates first authentication block information including first authentication information, which is obtained by encrypting a first hashing code generated by hashing at least a portion of security image data requested from a client terminal connected through a network with a private key of the camera device, and unique identification information of the camera device.

Abstract: The present invention relates to a pan-tilt-zoom (PTZ) drive apparatus and method for a camera, and enables a surveillance region to be switched at high speed to a target region of interest using a previous PTZ control history, thereby enabling rapid movement to a surveillance region in which a specific surveillance target has been found or a specific event has occurred to obtain a desired surveillance image.

Abstract: Disclosed is a technique for a railway disaster monitoring system for monitoring a foreign matter on a railway, which includes a camera and an image processing unit that receives a railway image captured by the camera. The image processing unit includes a segmented image acquisition unit that obtains a plurality of segmented images including a rail from the railway image received from the camera and scales the segmented images to obtain segmented image blocks of a predetermined size, and a segmented image determination unit which includes deep neural network (DNN) discriminators trained with deep learning neural networks and inputs the segmented image blocks to the DNN discriminators to determine whether the railway is in a normal state in which there is no foreign matter on the railway except a train passing by. Using the segmented images, a foreign matter on a railway can be rapidly and easily determined using a deep learning neural network even with a small number of resources.

Abstract: The present invention relates to a dome camera with an IR diffuse reflection prevention function to efficiently prevent infrared (IR) light from being diffusely reflected on an inner circumference of a dome cover and being incident on a lens module and prevent a surveillance direction of the lens module from being changed or an IR diffuse reflection prevention bushing from being deformed by reducing a frictional force between the inner circumference of the dome cover and a front side of the IR diffuse reflection prevention bushing when the dome cover is mounted.

Abstract: The present invention relates to a dome camera with easy gimbal operation in which a gimbal operation may be smoothly and continuously driven to prevent generation of a blind spot and also allows a user to more easily adjust a surveillance direction.

Abstract: A three-way parking control camera apparatus with a parking space displaying function is provided and allows occupants in a vehicle entering from a front side of a parking passage to easily recognize the direction of parking areas on both sides of the parking passage where there is an empty parking space.

Abstract: Disclosed is a PTZ camera operating system capable of easily and simply setting and monitoring a surveillance area through a user-intuitive surveillance area setting UI capable of setting the surveillance area from a hemispherical fisheye image generated using individual images within a motion range captured by a PTZ camera.

Abstract: Disclosed is an image analysis apparatus for analyzing a camera image. The image analysis apparatus for analyzing a camera image segments an input fisheye camera image into segmented images with a preset size field of view and superimposes the segmented images so that some regions overlap, performs dewarping on each of the segmented images, then combines the segmented images on which the dewarping is performed using a preset combination method, generates an analysis image, and detects objects included in the analysis image. In this case, the image analysis apparatus removes a result recognized as a duplicate from a detection result of the object by post-processing.

Abstract: Disclosed is a bottom housing for a dome camera having high heat dissipation efficiency. The bottom housing for a dome camera has an improved structure in which a bottom housing sub-plate made of metal is coupled to a bottom housing main body made of plastic, thereby achieving efficient heat dissipation and waterproofness and suppressing increase in manufacturing cost.

Abstract: A video security system with improved network response speed using pre-authentication information, which is capable of improving a network response speed by simplifying handshaking for securely exchanging authentication information and an encryption key in a process of starting communication between a client terminal and a server using pre-authentication information that is valid only for the client terminal, is provided.

Abstract: Disclosed is a technology related to a video surveillance system using a camera capable of a pan-tilt-zoom operation. The video surveillance system includes a pan-tilt-zoom camera for photographing a surveillance region, and a display device for outputting an image of the pan-tilt-zoom camera. The pan-tilt-zoom camera provides a fisheye image representing an entire surveillance region onto a first region of the display device, calculates driving parameters of the pan-tilt-zoom camera on the basis of location information of a portion selected from the fisheye image, moves the pan-tilt-zoom camera to a location of the selected portion according to the driving parameters, and provides a monitoring image of the selected portion photographed by the pan-tilt-zoom camera onto a second region of the display device. According to the present invention, the pan-tilt-zoom camera is allowed to be intuitively and rapidly controlled using the fisheye image and to rapidly generate a fisheye image.

Abstract: Provided is a video playback system based on approval of a playback approver. A decryption key that can decrypt an encrypted and stored recorded video is generated only when video playback is approved by a playback approver using an appointed playback approval method and transmitted to the video recording device so that it is possible to prevent leakage of the recorded video with sensitive personal information.

Abstract: Provided is a video search interfacing apparatus for efficiently searching for a plurality of recorded video channels by generating a search history by selecting cameras in a time series manner according to a traffic line of an object of interest on a map on which physical positions of a plurality or cameras are visually arranged, thereby searching for a plurality of recorded video channels more intuitively.
