Thanks everyone.The stuff GNUUU suggested seems nice but pricy... As for usb cameras it will be hard to use with a long extension (I don't think usb camera witll work with a 10m cable). Thanks for the info jxself. I was wondering the same thing.
So, best option so far, how to input commands into an old smartphone with no touch? OTG is off limits because the android version doesnt support it.
Thanks.
