The Z2 doesn't have an IR port so not sure how a remote would work - Does your camera have an IR port or is it able to work via the Tv sending the commands down the cable
I'm not aware of this however I am aware that you can use a Playstation controller connected via Bluetooth
You could consult with Xperia care who may have more detailed specific info on this for you http://support.sonymobile.com/global-en/contactUs/
