Hi there, neighbors! As mentioned above, the magnet on the No Drill Mount is intended to hold it in place when mounting, if it is on a magnetic surface. We’ve also seen neighbors use the magnet itself to mount the Video Doorbell. Please keep in mind the device weight, accessibility, and activity of the mounting area when deciding where to use this mounting method.
Feel free to also check out my Video Doorbell (2020 release) and No Drill Mount story. I hope this helps!
