A mounting system for an electronic device is described. This mounting system includes a base that can be rigidly mounted on or underneath a wall. Moreover, the base can be remateably coupled to the electronic device. The remateable coupling may involve pins that are inserted into corresponding holes and rotated into a lock position. Alternatively, the remateable coupling may involve magnets that mechanically couple to each other so long as the electronic device and the base are within a predefined distance. The electronic device may receive power via the remateable coupling or via inductive charging. In addition, the electronic device may monitor a spatial parameter, such as: a location of the electronic device, a velocity of the electronic device and/or an acceleration of the electronic device. If this spatial parameter changes without the electronic device first receiving a security code, the electronic device provides an alert.
