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 present invention relates to a system 1 comprising network-enabled surveillance cameras (PLC1-10, OfficeC1-OfficeC20 and SCC1-10). These cameras can be configured via the network with respect to a plurality of parameters such as their resolution “RES”, frame rate FR and microphone sensitivity ?.

Abstract: A retractable keel apparatus for a ship, in particular for a sailboat, including a lift device for a lowerable and retractable fin device having a fin (4) and a fin head plate (20) disposed thereon, the fin head plate making contact with a keel receptacle (5) provided for permanently attaching to a hull when the fin is lowered, the receptacle further having a locking device by which releasable locking can be produced between the fin head plate (20) and the keel receptacle (5). The invention should be designed such that, despite greater stability, including in the event of a crash, the device can be produced and integrated in ships as simply and cost-effectively as possible. For this purpose, the locking device has at least one, preferably a plurality of, preferably driven, longitudinally displaceable locking bolts (15) that can be displaced along a diagonally running displacement path.

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: A method for providing video data streams is disclosed. In an embodiment the method includes generating video image data by a digitally adjustable video camera arrangement and preparing the video image data by a reconfigurable logic cell arrangement, wherein during camera operation, settings of the video camera arrangement are changed, adapted reconfiguration data for the reconfigurable logic cell arrangement are calculated in view of the amended settings and provided to the logic cell arrangement, and wherein the logic cell arrangement is configured with the reconfiguration data at runtime.

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: 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 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 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: 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.
