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. ## Claims ### Claim 1 A surveillance camera system comprising: a series of cameras of which at least one is a surveillance camera having a network interface and storage means for video data storage within the surveillance camera, said series of cameras also including a plurality of other cameras that are accessible by the surveillance camera via the network interface for also storing video data from the surveillance camera and wherein the surveillance camera is provided with a selection means for selecting which of the other cameras, accessible via the network interface, are to be used for also storing video data of the surveillance camera; wherein the selection means is adapted to take into consideration in the selection at least one of distances determined by round trip times of data packets to the plurality of other cameras accessible via the network interface, distances to the other cameras accessible via the network interface determined by GPS sensors in the other cameras, and indications of the hazards the other cameras are exposed to, said indications being provided as information relating to the constructional adaption of the other cameras to hazards, the information being stored with the other cameras and transmitted from one camera to other cameras when the network structure is determined. ### Claim 2 (depends on 1) The surveillance camera system as claimed in claim 1, wherein the selection means is adapted to take into consideration in the selection both distances determined by round trip times of data packets to the plurality of other cameras accessible via the network interface, and distances to the other cameras accessible via the network interface determined by GPS sensors in the other cameras. ### Claim 3 (depends on 1) The surveillance camera system as claimed in claim 1, wherein the selection means is adapted to take into consideration in the selection distances to the other cameras accessible via the network interface determined by GPS sensors in the other cameras. ### Claim 4 A surveillance camera system comprising: a series of cameras of which at least one is a surveillance camera having a network interface and storage means for video data storage within the surveillance camera, said series of cameras also including a plurality of other cameras that are accessible by the surveillance camera via the network interface for also storing video data from the surveillance camera and wherein the surveillance camera is provided with a selection means for selecting which of the other cameras, accessible via the network interface, are to be used for also storing video data of the surveillance camera; wherein the selection means is adapted to take into consideration in the selection at least indications of the hazards that the other cameras are exposed to, said indications being provided as information relating to the constructional adaption of the other cameras to particular hazards, the information being stored with the other cameras and transmitted from said cameras to other cameras when the network structure is determined. ### Claim 5 (depends on 4) The surveillance camera system as claimed in claim 4, wherein the storage means for storing video data is designed for storing video data in an event-based manner with lead and/or lag with respect to an activating event. ### Claim 6 (depends on 5) The surveillance camera system as claimed in claim 5, wherein the storage means for storing video data designed for storing video data in an event-based manner in response to a trigger signal received from at least one other camera connected via the network interface. ### Claim 7 (depends on 4) The surveillance camera system as claimed in claim 4, wherein the storage means is designed for transmitting video data belonging to an event to several cameras provided for storage, addressable via the network interface. ### Claim 8 (depends on 4) The surveillance camera system as claimed in claim 4, wherein the storage means is designed for storing stored video data in such a manner that on request, all video data from a certain imaging camera or belonging to a certain event can be output selectively. ### Claim 9 (depends on 4) The surveillance camera system as claimed in claim 4, wherein the storage means is designed for time-offset storage in a networked-load-dependent manner. ### Claim 10 (depends on 4) The surveillance camera system as claimed in claim 4, wherein the storage means is designed for receiving video data from several cameras addressable via the network interface. ### Claim 11 (depends on 4) The surveillance camera system as claimed in claim 4, wherein the selection means is adapted to also take into consideration in the selection at least one of distances determined by round trip times of data packets to the plurality of other cameras accessible via the network interface. ### Claim 12 (depends on 11) The surveillance camera system as claimed in claim 11, wherein the selection means is also adapted to take into consideration in the selection distances to the other cameras accessible via the network interface determined by GPS sensors in the other cameras. ### Claim 13 A surveillance camera system comprising: a series of cameras of which at least one is a surveillance camera having a network interface and storage means for video data storage within the surveillance camera, said series of cameras also including a plurality of other cameras that are accessible by the surveillance camera via the network interface for also storing video data from the surveillance camera and wherein the surveillance camera is provided with a selection means for selecting which other cameras, accessible via the network interface, are to be used for also storing video data of the surveillance camera wherein the selection means is adapted to take into consideration in the selection at least distances determined by round trip times of data packets to the plurality of other cameras accessible via the network interface. ### Claim 14 (depends on 13) The surveillance camera system as claimed in claim 13, wherein the storage means for storing video data is designed for storing video data in an event-based manner with lead and/or lag with respect to an activating event. ### Claim 15 (depends on 14) The surveillance camera system as claimed in claim 14, wherein the storage means for storing video data designed for storing video data is an event-based manner in response to a trigger signal received from at least one other camera connected via the network interface. ### Claim 16 (depends on 14) The surveillance camera system as claimed in claim 14, wherein the storage means is designed for transmitting video data belonging to an event to several cameras provided for storage, addressable via the network interface. ### Claim 17 (depends on 16) The surveillance camera system as claimed in claim 16, wherein the storage means is designed for storing stored video data in such a manner that on request, all video data from a certain imaging camera or belonging to a certain event can be output selectively. ### Claim 18 (depends on 13) The surveillance camera system as claimed in claim 13, wherein the storage means is designed for time-offset storage in a network-load-dependent manner. ### Claim 19 (depends on 13) The surveillance camera system as claimed in claim 13, wherein the storage means is designed for receiving video data from several cameras addressable via the network interface. ### Claim 20 (depends on 13) The surveillance camera system as claimed in claim 13, wherein the selection means is also adapted to take into consideration in the selection distances to the other cameras accessible via the network interface determined by GPS sensors in the other cameras.
