There is so called SSTV which exists for decades already, and radio-amateurs use it for transmitting files (lot of pics too) from one computer to the other on VHF, UHF, often around the globe via shortwaves. Ham radio operators were exchanging written messages, and software too, long before internet came in our homes.
Files transmitted by radio waves through thousands of miles often arrive incomplete, or with significant noise due to atmospheric conditions which often vary and may be adverse to radio waves propagation in great distances, and/or electrical interference in cities when a receiving antenna isn't properly grounded.
But I was talking about several miles, or several hundreds miles away, not thousands. Transmitting pics or any other files is indeed possible, and ham operators are still doing it with perfect results when distance is not very large. Transmitting in shorter distances via FM within the same city or county works perfect.
Even transmitting around the globe works great too if there are enough radio-relays along the way which pick up the signal, boost it and propagate it further toward the destination.
There is even sstv-spam
where radio-operaters send out pictures addvertizing their station, or their internet site, p0rn web pages and similar... Google for sstv pics/images/photos...
Some of those "unsolicited" radio adds:
I was asking if anyone know if there is any device that could be attached to a DSLR camera and use the existing way of radio transmitting files (SSTV) to store pictures on a remote location instead of storing pics in a camera.
It needs only a small transmitter and a demodulator to convert binaries into a radio signal. That's how sstv transmitting works.
The way of storing pics via radio waves to a remote location exists. I couldn't find anything about DSLR and SSTV online, so perhaps I am Googling just by wrong keywords or, don't know where to look, or sstv hasn't been implemented in DSLRs attachments. Or maybe it's been implemented under a different name ?
