Proximity is great and all, but there are so many false positives it’s an absolute pain.
A laser ‘trip-wire’ is literally all I want: has something broken the beam at say, waist height? Yes. Then I want to know. Can I now cover an entire driveway threshold and know again if the beam has been broken? Yes.
These things are insanely cheap, compact and basically all that’s missing is Eufy integration.
Basically anything is possible minus a whole bunch of the annoying false alerts!
