Welcome to the forum. I assume you are asking about a remote control solution for your camera that includes a bigger monitor than the camera has. I have used this DSLR Controller :: Home app for Android devices with lots of success on a Nexus 7 tablet. The app is free but you need some cables and dongles, and if you follow the instructions, there is both a wired and wireless remote control. Also if you have a laptop, you can download the Canon EOS Utility from the Canon Website that works with the camera to allow remote control from the laptop.
