Camera theft is always a concern to photographers. Unlike many electronics that connect to the internet or cellular service, cameras that are stolen are inevitably gone forever. There is no deactivating, no locking, and no real recovery methods (CameraTrace & Stolen Camera Finder aren't perfect). However, Nikon is looking to change this, with password protection of your gear.
According to a recent patent filed by Nikon Japan, the future of password protected gear is not far off. As all patents are, its a bit difficult to understand, but Nikon Rumors suggests that your camera body and lenses would link together, and be nonfunctional without a password entered into your camera body.
