If you buy a new digital camera
Take a photograph of your contact details - that way if you lose it and it's found by A Nice Person, they might think to check, and if so will be able to get in touch.

(Alternatively, if you already have a digital camera, delete all your photos and do the above).

Or use your work address
Not everyone can be trusted with the burglarable home address of the person who clearly is rich enough that they have bought so many digital cameras that they can just leave them anywhere

By "contact details"
I was thinking mobile number and email address. For the above reasons.
