Can I search for movement in just one area of the image?
Yes, and it is the search that pays off most. You draw an area over the recorded image —the shelf, the door, the gap where the goods were— and the system goes through the period you set and returns only the moments when there were changes inside that area. It is done after the event, over what is already recorded, and it does not need anything to have been configured beforehand.
It works well on stable indoor scenes and worse outdoors with vegetation, shadows that turn through the day, rain or sudden changes of lighting, which throw up matches that are of no interest. You tune it by making the area smaller, raising the sensitivity threshold and narrowing the time band.
There is a technical limitation worth knowing about: on systems where this search is done by analysing the recorded video at that moment, going through many days of many cameras loads the server and takes time. On those where the movement information was saved as metadata while it was recording, the search is almost immediate. It is a difference of architecture between platforms that you only notice on the day you are in a hurry.

See it working.
A written answer is enough to decide whether it interests you. To know whether it works at your site you have to see it on a real scene, with the image as it is and, on top of it, what the system understands from it. That is on the IRIS Neural website, which is the group's product.
