If you don’t mind fiddling around with configuration files and integrating another piece of software to your system, you might want to check out Shinobi CCTV with Tensorflow integration.
I use it to detect car on my driveway, people walking by my doorphone etc. Will do a writeup of how I did set this up some day.
With object detection (and enough confidence) you can e.g. turn your driveway lights on or warn you that someone’s at your property after midnight.
I detected a pack of foxes having fun with my watering pipes the other day
