Wall Mounted Pan Video Camera Are There Any TV Wall Mounts That Move In The Vertical Direction?

Are there any TV wall mounts that move in the Vertical Direction? - wall mounted pan video camera

I am looking for a wall mount for my 42 "plasma that can do everything. I do not want me in and out of the wall, go left and right, and above all I want to be able to vertically upwards and downwards move. I do not tip over, everyone knows if it is a question? The movement up and down is very important.

Thank you!
