This feature would be very helpful. Any hall or other taller than wider cases would greatly benefit from this simple option.

I can't believe I wasted my money!!! I saw Tapo advertise its "wall" mount. I bought the c210 expressly because of the only location I can put it. 
 

and now I discover a simple thing like 90degree rotation is not possible. What a joke - now I have to find a wall mount to stick out from the wall to compensate for a lazy software development by TP-Link. I see this feature is on Kasa - so clearly your techs know how. Just too lazy to roll it out. So disappointing from what I thought was a great home automation company.

i strongly urge you to take down your misleading camera on wall mount video until you put a disclaimer that all images will not appear properly if this is done!

  @Solla-topee This seems silly.   The camera is advertised as coming with a wall mount.  Logically, if you mount the camera on a walll, it will be sideways, which requires a 90 degree rotation.   Why advertise a wall-mount if that's not supported?   What you have is a shelf or ceiling mount only, NOT a wall mount.

I am also wondering why Tp-Link put such a mounting video on the wall even the camera is not capable to rotate Image 90 degree.
