Here’s my two cents...
In few days we will be in 2025, but I'm still using Deepstack version 2022.01.01. GPU version with NVidia 1030 and 2GB VRAM. I'm using community Custom model from MikeLud1. On 4/8 cameras I just confirm person or vehicle for camera ONVIF event (Andy's T5442 variants), and other 4/8 are configured in BlueIris to do triggering with AI. My confirmation times are in range 40-200ms, it depends. This configuration is rock solid for almost 2 years. I couldn't be happier.
@MikeLud1 - Would it be possible for you to release/build a large version of the ipcam-general model? I get better results with the yolov5l.pt model, but I don't require all the junk in it like plant pot, microwave, zebra etc, etc only vehicles and people.
