I did some tinkering with my #HomeAssistant setup, and I've now got it configured to deliver person/vehicle detection notifications from my Reolink cameras. Getting it to include a snapshot in the notification took a bit of doing. I've got some more tweaks to do (rate limiting, scheduling, etc.) but I'm pretty pleased with how this works now.
I think I'll probably do a writeup on the whole thing once I get it squared away.
Rate limiting is sorted! I created a 5-minute timer for each exterior camera, and added a condition to the automation to only fire if a given camera's timer is idle. The timer then gets started after the notification is sent.
This way I'll only get one notification every five minutes for a given camera, but I'll still get notified if the person moves from one camera zone to another.
Here are some notes I wrote on how I'm now using #HomeAssistant to manage notifications from my Reolink security cameras:

I'm really happy with this setup now!
