The Triggertrap cables connects your DSLR camera to your phone/tablet to allow you to remote trigger your camera. Also allows for triggering your camera based on time, sound, distance. The software is available on both Android and iOS. The cable with the box converts the audio controls into signals your camera understands. The second cable is the adaptor to plug into your brand of camera. I have two adaptor for my different cameras while I just have one control cable.
It comes with the correct cable if you order the canon version. I found it to work fine.
If you are using it with an android phone it has a few less features than the iOS app does but nothing major.
Iuse with Android and my ipod touch. I hope this helps.
