A system to facilitate management of surveillance devices, that are distributed over a monitored region, through a geographic information (GI) portal, having GI storage to store map data defining a geographic map of the monitored region. A GI manager unit (GIMU) to record, in the GI storage, asset position information with regarding locations for assets of interest within the monitored region. The GIMU obtains, from a remote surveillance device (SD) database, device-related records. The GIMU stores the device related records in the GI storage. The device records are associated with the surveillance devices installed in the monitored region. The device records include position tags that identify a location of the surveillance devices in the monitored region. The GIMU obtains, from a remote network (NW) database, network-related records. The GIMU stores the network related records in the GI storage. The network-related records associated with network devices are installed over the monitored region. The SD and NW databases are maintained and managed separately from the GI database by one or more independent management units. A display presents a geographic map of the monitored region with device markers and network links illustrated thereon. The device markers indicate positions of the surveillance devices relative to the geographic map. The network links indicate communications links between network devices. A user interface permits a user to select from the surveillance devices and network links. The GIMU makes available to the user the device related records and documents and the network related records and documents associated with the selected surveillance devices and network links.
