InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
I've been using Frigate which is open source, supports the usual motion detection, zones and does impressive object detection. Practically supports any video camera that has an accessible live stream, although it can sometimes take a bit of fiddling to configure. Can also be integrated with home assistant if you're in to that.
