Python and Yolo expert

Hello,
i have a project in order to detect animals in live camera and save images and video of the events.
We want to use YOLO so we want a expert to do this.
All the work need to make remote with ssh.
This is how they work:
The script tun on ubuntu server (no gui) 22.04 with nvidia GPU.

1rst part:
Connect to 4 live cameras and detect animals.
When they find a animal, they add to mysql the event data (timestamp, type of animal, name of related image, name of related video).

2nd part:
to optimize the system and if the animal come near they run the file a1.sh
If the animal come even more near then run the file a2.sh
(we can see if the object come near based of the changes of size of the object).



The script must be work with both, recorded video files and live stream from ip camera.
I have datasets for the training but i want instructions how i can train the yolo model.
All code must be unlocked with comments to make the read easy.
