It’s built into the newer cameras and you need an NVR with the newer hardware to run them. I don’t know the rev number off the top of my head.
I went from a few hundred alerts a day from just 2 cameras to less than 50 from 6 cameras. And those 50 alerts are mostly legit with either the mail lady, us coming or going or neighbors walking by on our side of the street.
I had to buy a newer NVR and I’m slowly upgrading all my cameras to AI. I did all the ones in the front of our house first and just ordered two more for the back on Cyber Monday pricing. I think I have 4 left that are not AI.
My wife still gets a few hundred emails a day from her parents cameras. They have been getting all our old 4k cameras without AI and she insists on getting alerts from every camera, lest she miss something. I’ll be upgrading them to AI as soon as she green lights the expense.
