Hi all, really simple question for someone I hope :-)

I have an Android Tablet hanging on the wall with no password etc. I use it for CCTV at home and video door bell. When someone rings the door bell the tablet makes a noise but stays asleep - is it somehow possible to have the tablet wake up when the door bell rings and to jump straight to the app which runs the video door bell and show the image of the person there?

Many thanks

Paul
