If you have an Rpi lying around you can also setup MotionOS on it and use it as the server. Its far more reliable than TinyCam which Ive found often kills the resources on your tablet - DEFINITELY dont use this on a fire7/8. they just dont have the processing power/ram. Works ok on lenovo Tab 4 8". There are also issues with the fact that each one can only push 3 camera feeds and to a max of 3 devices before it bombs the server. So its not going to work for you if you are broadcasting to a tab in each room in your house.
