I want to cover a stairway. The motion detection camera that is in the library here is a very good start. I want to add the following functions.
1. long battery life 30 days min.
2.. Rotating photo storage. i.e. when the memory is filled up, the camera will overwrite the oldest photo.
3. Date and time stamp
A unit like this could be left in place for a long period and only accessed if something has happened that need to be checked.
