I learned the hard way that mounts designed for Blink XT and XT2 cameras are incompatible with the Infrared sensors on the new Outdoor and Indoor cameras, even those most of those mount manufacturers claim their mounts are compatible with the Outdoor/Indoor cameras and even show photos of them being used this way.
The problem is the Infrared sensors are along the sides of the lens in the new cameras, and the older mounts are usually designed with vertical slots for the lens, thereby blocking the IR sensors. When the IR sensors are blocked, the motion detection will never work right, and the cameras become useless in the dark.
It’s frustrating dealing with either dishonest or ignorant 3rd party manufacturers who don’t know their mounts are incompatible.
So just be careful. For the Outdoor/Indoor cameras to work right, the entire front of the camera needs to be uncovered.
