Abstract: The presence of a stationary object is to be reliably recognized. Thereto, a presence detection device for detecting a presence of an object in its environment is provided, which comprises a movement detection unit for detecting an initial movement of the object in the environment of the presence detection device and for outputting a movement signal depending on the detection as well as a control unit for generating an activation signal depending on the movement signal. Moreover, the presence detection device comprises a camera, which can be activated by the activation signal, for obtaining a video signal of the environment of the presence detection device and an evaluation unit for generating a presence signal relating to the presence of the object by evaluating the video signal.

Abstract: A method for evaluating positioning parameters in a defined area, wherein the defined area is affected by at least three stationary access beam points and over which a grid pattern is laid with at least two grids, each grid having an anchor. An initial vector of positioning parameters is assigned to each anchor and a plurality of RSSI measurements are captured within the defined area by receiving signals from the at least three stationary access beam points. The plurality of RSSI measurement are clustered in a plurality of subsets, wherein the number of subsets corresponds to the number of the at least two grids. Finally, each subset of the plurality of subsets is associated with a respective one of the at least two grids and the initial vector is updated based on the subset of the plurality of subsets associated with the respective one of the at least two grids.

Abstract: A system for providing a wireless network may include a plurality of wireless access points for a delimited spatial area in a building or physical structure. At least one spatial zone controller may be connected to at least some of the wireless access points and is configured to receive, via the wireless access points connected to the controller, device information regarding a terminal logging into the network and/or regarding an external wireless access point, and to determine the spatial position of the terminal and/or of the external wireless access point or the physical structure. In addition, a central security controller may be connected to the spatial zone controller to provide an access control list. The spatial zone controller may be configured to compare the received device information and the determined spatial position with the access control list.
