Is there a way to bypass saving camera images to a pc rather than the memory card? Answered

I have a Samsung NX1000 camera that has to take 1000s of images and its annoying having to take it off the tripod to take the card out when it reaches its max 9,999 image to transfer then put back in to continue (telecine hence many images!).

I'd like to get something like attached images which I can use to have the sd card hang out of the camera for ease of access without removing camera off tripod but ideally can save directly to a usb hard drive or to a pc (that I guess would need to emulate being an sd card)?

This would save a lot of time transferring images. Using wifi cards are far too slow and a bit a bit buggy.

Thanks for any thoughts.

Have a look at WiFi enabled SD cards.
They are basically a SD card with a built in WiFi module.
Means you can access the files from the cam directly over your network.
Just picked one quick link from the search as an example, shop around for better prices or more storage space:
https://www.amazon.com.au/Toshiba-FlashAir-Wireles...

Some other link that might be of interest:

Generally the problem is that from SD to HDD or similar you need to convert and match the different signals and protocols.
To keep a reasonable speed the transfer chip needs be faster than the attached devices.
And sadly not too many people develop for this as not too many people need such a solution outside the development areas.

Most digital cameras out there can act like a USB mass storage device, aka, MSC, UMS.

https://en.wikipedia.org/wiki/USB_mass_storage_device_class

You know, connect the camera to a computer via a USB cable, and then magically the camera's memory card looks like part of the computer's filesystem, complete with files and folders and subfolders, and the usual operations for those, e.g. copy, delete, etc.

What you might not have known about is this other, over USB, protocol called, "PTP (picture transfer protocol)".

https://en.wikipedia.org/wiki/Picture_Transfer_Protocol

The neat thing about PTP, is some implementations of it include ways to actually command the camera, over the USB cable, and make it do things, like take pictures, or zoom, or lock the focus, or enable the flash, or a myriad of other things.

Moreover there is a command line program called gphoto2,

http://www.gphoto.org/doc/remote/

so that human users, who want to command a camera via usb cable, can do so, in a relatively straightforward way, via the linux command line, aka bash, with commands like, for example:

gphoto2 --set-config capture=on
gphoto2 --set-config zoom=4
gphoto2 --capture-image-and-download

http://www.gphoto.org/doc/manual/ref-gphoto2-cli.html

I guess if you are a real programmer, you would use the actual library, libgphoto2, but for lesser hackers, I think bash, and simple shell scripts for the same, are the way to go.

The catch of course, and of course there is always a catch..., is this remote control magic is NOT supported by every camera out there.

Thus the camera to be controlled, via gphoto2, has to be one of the ones in their list, here:

http://www.gphoto.org/doc/remote/

If you are totally comitted to using the camera you have now, then me telling you the gospel about gphoto2, might be kind of a waste of time, unless your, "Samsung NX1000" happens to be on that list of PTP controllable cameras.

Some cool info there and looks like NX1000 is supported but unfortunately I use the usb as a trigger from an Arduino!

Not to be flippent, I think manufactures have SD cards so when you get on full, you put in another. With a few extra cards one card can download why you shoot with another. The the high rate of images, if your burning through them its more like video. There are survallance cameras that connect direct to hard drives that would provide continous images and those could then be edited to which ever frozen picture. RJF
