I assumed they were for Blink cameras. The formulation of the product suggests this. When I received them the cameras fitted perfectly, they were easy to install and had a good reach to aim the camera. I found that the opening for the lens, motion sensor and microphone was too small for the IR camera to detect darkness and hence the night vision didn't work. The footage was too dark to see anything because the IR sensor was obscured. It's to the right of the camera lens and you wouldn't have guessed it was there unless the Blink support rep told you like I did when I contacted you. I replied to Blink's maintenance staff, Abby, who assumed she had heard that you had enlarged the hole to reveal the IR sensor. So the ladder and the Dremel tool reappeared and I did as she suggested. Now they work fine. Glad I asked because I was about to throw the blanket away, I was so offended. attach photo.
