For the least amount of setup I would use a Grandstream SIP camera like the GSC3610 but any camera in their lineup will work. Then in the camera there is an option to set up an alarm to ring any SIP endpoint when motion is detected in a certain area (you can just put the IP address of whatever endpoint you want) that could be a VoIP phone, speaker, control panel etc. Also the camera lets you have multiple schedules on different days and whatnot. I use one as a driveway alarm and have had pretty good luck (other than a false alarm when it swaps from day to night mode, but that can be worked around). You could also do this with a Reolink camera if you want it to ping an app on your phone (that would also work even if you aren’t home).
