This is my favorite mount for the Blink XT or XT2 cameras especially of you have areas that are hard to mount to camera to (i.e. bird poles, etc.). You can also use this mount for DSLR, Trail Cameras, etc. as the Blink adapter can be removed thus exposing a standard 1/4 inch screw. There are multiple sellers on Amazon that sell this product, but the one in this video is this one: amzn.to/3vGEfus
