I am aware of tracking mechanisms for laptops with a combination of hardware/software solution that help the owner to track lost machines. I was wondering if there is a similar solution for tracking DSLRs? Do any of the GPS modules available for some DSLR models allow you to do this?
A DSLR doesn't have a cellular or network connection, so there would be no way to have it report it's position. Some DSLRs include the serial number of the camera body in the EXIF meta data on an image, so if someone posted an image online with that meta data intact, there is a chance it might get indexed by something, but that's a long shot at best. It's also information that can be easily stripped from images or even permanently altered in the camera.
So no, in short there is no way to track a DSLR camera that is lost or stolen. At least not a reliable one that can't be easily worked around.
Actually, there are some ways you can go about this.
There are actually services that pull exif data from sites like flickr and 500px which collect the serial number data embedded in an image you've previously taken.
If you find any photos from your camera online, its worth while then checking the exif data to see if there's any GPS data stored in it. As it stands however, there's no dedicated GPS/radio tracking available for cameras specifically at this time.
Hope that helps!
There are external hardware gadgets such as the Zoombak that will let you track an object. The hitch is that once the battery runs out or it's away from an area where mobile service and either satellite or assisted GPS are available, you won't be able to find it. They're also bulky and obvious enough that the first thing a thief will do is remove it. A vindictive thief could leave it someplace that would send you on a wild goose chase.
For the price of something like that plus the service, you could just as easily insure it and get it replaced if it disappears.
