The base unit includes several mounting sockets arranged at different elevational and azimuthal directions around the base unit, and the sensor modules attach to the mounting sockets. Each mounting socket includes a socket ID, which is used to stitch together the image data from different sensor modules. The sensor modules are powered wirelessly via induction and communicate wirelessly with the base unit via wireless transceivers and antennas. The security camera system is capable of automatic detection of the location of the sensor modules, as the socket IDs for the mounting sockets to which the sensor modules are attached are identified by various means including wireless beacons, signal strength positioning and/or triangulation, or via a temporary provisioning bubble that arranges socket ID designators in fields of view of each of the attached sensor modules. ## Claims ### Claim 1 A security camera system, comprising: a base unit including a mounting dome having a plurality of mounting points;
