Just bought these. Everything works well except the mounting bases for the cameras. As you mentioned in this video, the cameras are heavy (10 ozs,, 0.64 lbs., 289g). The base is plastic and relies on the plastic threads to create enough force/squeeze the post so camera does not slip down. I had to modify base to increase force otherwise camera was not held firm. I had to make really tight so hoping plastic doesn’t break. Also the three 1/8 inch (0.125” OD) threads are also lacking.

Mine isn't picking up motion 😕. I can watch it live and all but can't go back and view anything
