If your computer doesn't have a card reader, you can purchase an external adapter that connects via USB.
For connectivity, WD 1TB My Passport Wireless offers a Wi-Fi 802.11ac option that can be used with iOS and Android app for WD, along with a USB 3.0 port. The hard drive is enclosed with a durable, shock-resistant case.
You can read unbiased product reviews and compare prices online. L brackets, clamps, and glue I suspect :)
I currently have a microSD breakout installed inside the machine for some image files that are used, so I could use an extension from that, put the images (locked) on to the full-size SD card, and mount the reader somehow in the panel. So far this is what I'm leaning towards.
