PopPhoto reports about a new site GadgetTrack that tracks if your stolen camera has uploaded images to flickr or 500px

John Heller was on assignment for Getty Images at the Egyptian Theater in Hollywood, when his Nikon D3 and lenses were stolen, but it wasn’t until a substantial amount of time later that he searched for the camera’s serial number on GadgetTrak’s service, which has indexed all the serials embedded on images from 500px and Flickr from 2006 onwards. With a positive hit on a couple of photos on Flickr, the police were able to track the camera down to a photographer, who bought it not knowing its origins — and even had a receipt for the transaction.
