Response to: Bluetooth?

I know some cameras or at least video cameras have bluetooth, or now even WIFI, but I don't know of any that communicate with each other. Not sure of the goal of them communicating with each other?


On the other I believe that at least some of the two way radios that have built in GPS recieves exchange the GPS data with each other. This sounds very cool and usefull. Each person in the field will know where the others are.


As far as storing the GPS data as an EXIF field, if a camera stores it then most programs should support viewing the data. I believe it is a standard EXIF field.

  • Why bluetooth-enabled cameras?

    If your camera could communicate with your cell phone (via bluetooth/wifi/etc), you would get geotagging via E911 technology and unlimited storage via 3G/4G.

    That's pretty cool.

      Does the E911 work like GPS but just use signal strengh or time from various cell phone towers?

      Kevin, I mis-understood your post, but now it makes sense. I thought you were talking about a camera communicating with another camera, vs communicating with GPS device (now it makes sense, that woudl be great. In fact that is similar to what the Ricoh camera does which has a GPS card. It just does not do it wirelessly.

      One other feature that would be great is to record the heading as part of the track. If you have an electronic compass on the GPS receiver it can tall which way you are looking (assuming you have the reciver taped to the camera or aimed the same way). I think most of the standard track formats record location but not heading.
