This is my first design so I'm still learning.
I bought this wifi camera INQMEGA HD from Aliexpress for about $25 and it is working pretty well for the price. However, it is made to work on top of something (table or something else) and the support that comes with it makes it stand horizontally. While it still works, the camera movement is not very good at this position.
Therefore, I decided to make my own wall support that would allow the camera to be vertically and work properly. Although it may need improvements, it works very well for me. Feel free to try.
