Wi-Fi SD cards are mostly used with camera in order to wirelessly transfer photos or/and videos to your computer or mobile device without having to take out the card or transfer them via a micro USB cable. I first discovered this type of card with Toshiba FlashAir in 2011, but now EyeFi seems to be the most popular brand, and comes in different sizes with the 8GB Wi-FI SD card selling for $44 on Amazon US. There are cheaper alternatives with some Wi-Fi SD card adapters accepting micro SD card selling for about $15 and up on Aliexpress or Buyincoins, and DX calls it CY EP-027, but sells it for $23. It does not come with storage but since a 8GB class 10 SD card now costs about $8, it’s still nearly 50% cheaper compared to the 8GB EyeFi SD card.
- Max micro SD card capacity – 32GB (SDHC/SDXC)
- Connect up to 3 devices simultaneously
- Supports “with the beat-per-view” feature, which probably mean “Shoot and View” so that you’ll see the picture on a bigger display, as soon as you take it with your camera.
- File formats supported: Photo (JPG, PNG, BMP), Video (MP4, AVI, MOV) and Music (MP3, WAV)
- WiFi/SD settings: WiFi password, AP Mode and Station Mode switch, IP, channels, number or users, SSID.
- Default passwords – Wi-Fi: 99999999; App credentials: admin/admin
The card is said to work with Android and iOS devices, as well as computers.
To use it, you need to insert a micro SD card in the adapter, insert the adapter into your camera, then locate the Wi-Fi hotspot with your device or computer and login with the default password. Now open you browser, and you should be able to download the app. Alternatively, you can also download [email protected] app from Google Play or iTunes.
I could not find the manufacturer, and the app developer “Key Technology” only setup a place holder blog, probably to comply with the app stores’ requirements to have a support page.
Thanks to Onebir for the tip.
