Eye-Fi WiFi SDHC cards (feedback)

By Dale Reagan | January 6, 2011

Eye-Fi Model:  Connect|X2, 4GB +WiFi

I am exploring this card using a new DSLR camera that supports it.

First, my expectations based on product feature list from the sales site (an Amazon store):

Additional expectations (yours may certainly be different)

The packaging is mis-leading – it states:

Eye-Fi Model:  Connect|X2, 4GB +WiFi


Bad news

Software – Adobe AIR application

Installation is ok but:

Since there is no real documentation (at least not with the package I purchased) here is a bit more information on using this card:

Performance Quirks for the Connect | X2 card

Privacy Items


Some Additional Caveats (from the web pages)

“If you plan to give or sell a previously registered Eye-Fi Card you will have to delete the card from its associated account before it can be registered and used by another person. For instructions about deleting an Eye-Fi card from an Eye-Fi account refer to How do I add/delete an Eye-Fi Card to/from my account?.”


“If you plan to purchase a used Eye-Fi Card, it is imperative that you make sure that the previous user has deleted the Eye-Fi account associated with the Eye-Fi Card you plan to purchase. A previously registered Eye-Fi Card cannot be re-registered to a new user until the previous account has been deleted by the original owner/user of the card.”

Based on additional reviews it seems that Eye.Fi has always required some level of Internet access going so far as requiring uploads from camera –> local wireless access point –> the Internet and then BACK to your PC…  Based on my testing this is no longer a requirement.

FYI – to avoid the possibility of your photos ‘leaking’ out of your network you could create firewall rules to block all access to the domain.

Reviews from 2008 (when the product was introduced)

In depth look at the technology:

Security Concerns:

——- start of quote – with my formatting ——

Editor’s Note: submitted this article to the Eye-Fi dev team prior to its posting to give them time to address the issues we uncovered. As a result, the Eye-Fi is now a much more secure solution. They have addressed (or will address shortly) all of the issues raised in this article, and have demonstrated their ability and desire to properly secure the Eye-Fi. As with any product, be sure to update your Eye-Fi software to the most recent version prior to usage.


It is important to note, as the Eye-Fi dev team pointed out, some of the following issues are not security risks directly related to the Eye-Fi product. Ultimately it is up to the user to take responsibility for their actions and to use secure operating procedures. Again, the Eye-Fi is a superb product, and their professional and courteous response further proves this point. When it comes to security, it is a company’s ability to understand, accept, and respond to software bugs that makes the difference — and we are convinced that the Eye-Fi team “gets” this important issue.”


  1. * First, if the wireless network is not encrypted (i.e. a hotspot or insecure SOHO network), the images can be captured very easily. .
  2. * Second, all wireless networks are susceptible to DoS attacks.
  3. * Finally, your Eye-Fi card is susceptible to man-in-the-middle attacks if you have enabled a photo sharing service.


When you upload an image to a private photo storage site, you are trusting a website to be 100 percent bulletproof. Unfortunately, this assumption is just not realistic. This issue has nothing to do with the Eye-Fi, but users should be aware of the risks associated with sharing images.”


The Entire 2/2008 Article by: Seth Fogie –

——- end of quoted text ——

In the fall of 2010 announced a developer program – I submitted my request the first week of January, 2011 (about the time of this post.)  While there is no open, published API for the Eye.Fi card there have been some open source efforts at creating ‘solutions’; I tried several (under Linux) with un-successful results.  I see a host of possible uses for this card (near real time ‘publishing’ or simply remote uploads from ‘the field’) – lots of potential for useful software (just keep an eye on security issues if using this device & especially if creating software for it…)

The Eye-Fi Web site – many forums, FAQs, etc. – overall seems to provide good/reasonable consumer level information (but not so good technical product information…)

As with all  of my posts, your mileage should vary along with your opinions (well, at least a little bit…)  🙂
