Good day!
Do you know working analytics with the lost thing?
I use my wife. The whole family knows it’s only lost if Mom can’t find it!
What you are asking for is usually called Object Missing, although I don’t remember an analytic determining what type of object went missing, only a large change of pixels in a specific area over a period of time.
I say “usually” because the analytic “loitering” or “Object left behind” can be use for graffiti detection.
If you are asking who makes a good one, well that’s depending on the environment and the price you are willing to pay.
We have an analytic for object removal (used in places like art museums) which creates an event when it is tampered with or removed. We also have smart searching which lets you search for changes within a box you make on the screen, and so if you know where the object was you can put a box around that area and only see when that area changed.
