Frigate is incredible. I have 3 instances of it (different homes across the family) running using various amcrest and reolink local-only PoE and Wifi cams. I access the remotely using wireguard. One is running on a 2017 miniatx box (Intel i7-7700T) using openvino to do local-only object detection with the 2017 intel CPU. One is using a Beelink EQ14 Mini PC, Intel Twin Lake N150, also using openvino for object detection (people, dogs, cars, etc). One is using a nvidia 5070 gpu. All notifications are processed via the home assistant integration.

Truly top-notch quality, full-featured, very low maintenance, easy to set up, cheap to operate. I'm glad so many people are using it now.

For video doorbell I just have a cam that can see the front door and I drew a box around the area I want notifications for. When a person enters the box, I get a notification and snapshot.
