I’ve combined a Wyze motion sensor with a camera mounted inside a front window to let me know when my mail has arrived. I mounted the motion sensor inside the back of my wood mailbox at the curb:
Here is the video capture triggered by the motion sensor when the mail arrived:
I find it interesting that the mailbox being opened is way at the end of the 12 second clip, but that may be due to the camera also being set to capture motion.
The motion sensor is about 100 ft away from the camera with the bridge (not the same camera that’s recording the video); about 85 ft outside and 15 ft inside; through one exterior wall which is mostly glass. The signal strength of the sensor shows good (three bars).
