Abstract: The invention relates to a surveillance system having an image recording means for recording optically distorted images and having a transmission means for transmission of image information from the image recording means to a reproduction means which reproduces, in an undistorted form, image details of the images which have been recorded with optical distortion. In this connection, it is provided that the transmission means is designed for detail transmission of distorted images and for joint transmission of additional information, which allows image detail distortion to be corrected, in order to allow distortion correction in the reproduction means.

Abstract: The invention relates to a method for memory management, in which memory usage data relating to the use of the memory is recorded. The memory usage data is determined in response to a number of memory write and/or read accesses.

Abstract: The invention relates to a monitoring camera arrangement, having at least one setting axis for setting a monitoring region and a detection means in order to be able to capture and signal changes of the monitoring region. According to the invention, the detection means comprises at least one monitoring image-independent tilt detector in order to signal a monitoring region change in response to detected tilt changes.

Abstract: A seal for a plug connector arrangement having a plug which is intended to latch into a standard socket in a releasable manner, wherein the seal is formed with a latching suppression means for permanently preventing the plug from latching in and with a pushing means for pushing the plug, which is not latched in, into its standard contact position.

Abstract: A surveillance system with cameras, monitors and a connection medium. Provided in this connection are a response code memory for the storage of response codes by which image data can be retrieved by cameras and response code generation media which are allocated to the monitors and generate response codes which indicate which cameras should retrieve image data, whereby the connection medium is designed for the purpose of through-connecting image data to the monitors in response to the response codes generated by the response code generation media allocated to the monitors.

Abstract: A module frame for bell system modules having a module locking means for locking modules, which are to be inserted, to the frame and having a locking canceling means for canceling locking during actuator excitation. In the process, provision is made for the locking canceling means to also exhibit actuator-independent permanent catch blocking which can be selectively activated.

Abstract: The invention relates to a surveillance camera having a network interface and a storage means for video data storage within the camera. In this context, it is provided that the storage means is designed for storing video data to be stored in at least one other camera accessible via the interface and/or for storing video data received from at least one other camera via the network interface.

Abstract: The invention relates to a method for controlling communication between at least one stationary and at least one mobile, data-exchanging unit. In said method, a position of the mobile unit is determined, and communication is made possible in response thereto. According to the invention, a priority measure is determined in response to the determined position, and data can be transmitted from the mobile, data-exchanging unit according to the priority.

Abstract: The invention relates to a digital video camera comprising an image sensor that generates an image data raw stream, and comprising a memory for storing image data generated in response to the image data raw stream, and comprising a data output unit. In this case, it is provided that the data output unit is designed for outputting image data generated in response to the image data raw stream to the memory and for simultaneously outputting image data and for simultaneously outputting image data from the stored data from the camera to users.

Abstract: A digital access control system including an input mechanism which can be operated from an unprotected area and a barrier which opens in response to operation of the input mechanism, wherein an energy store for supplying the barrier with opening power and a communication line for communication with a remote unit in the secure area are provided and the energy store is in a form of a low voltage buffer store and, for supplying power to the low voltage buffer store, a low voltage communication line is provided which has an associated low voltage Power Over Ethernet unit or an associated unit from a similar standard.

Abstract: A video transmission method in which temporarily recorded video data are partially transmitted to a video data backup unit. In this case event-based identification data are concomitantly recorded during the temporary recording and only video data identified by identification data are transmitted to the video data backup unit.

Abstract: The invention relates to a method for displaying camera images on a remote, mobile viewing device, the viewing device having a screen with a different number of pixels in the longitudinal and transverse directions, a position sensor for determining an orientation of the viewing device and a request means for requesting camera image data from the camera arranged such that it is remote from the mobile viewing device. In this case, provision is made for the position sensor to first of all be used to determine whether the screen is oriented for displaying a portrait or landscape image, for an item of information based on the orientation detected using the position sensor to be transmitted from the mobile viewing device to the camera in order to request a camera image formatted in accordance with the portrait or landscape orientation from the remote camera via a bidirectional communication channel, and for the camera image to be received and displayed in the corresponding screen orientation.

Abstract: The invention relates to a camera arrangement having at least one wide-angle camera for monitoring an elongated space, and to a mount for the camera. It is provided in this case that the mount is designed for directing the wide-angle camera with a field of view of low distortion onto distant parts of space, and for directing the wide-angle camera with a field of view of higher distortion onto closer parts of space.

Abstract: The invention relates to a method for generating video stream data relating to different fields of vision from a camera having a sensor which records high resolution images in a distorted manner. According to the invention, image corrections are performed for separate fields of vision, and a total video stream is output from the differently corrected image data.

Abstract: The invention relates to a monitoring camera arrangement, having at least one setting axis for setting a monitoring region and a detection means in order to be able to capture and signal changes of the monitoring region. According to the invention, the detection means comprises at least one monitoring image-independent tilt detector in order to signal a monitoring region change in response to detected tilt changes.
