How do you find something in weeks of recording?
Not by watching the video, but by cutting it down first with filters. The order that works is: narrow the time window with whatever you know, choose the cameras that could have seen it, and then run a search over that which throws out what does not matter. Running through hours at fast speed is the last resort and nearly always the worst.
The tools the systems bring are three, from least to most. The timeline with the activity marks, which shows at a glance where there was movement and where there was not. Motion search over a zone drawn on the image. And, on systems that carry analytics, the filter by object type: people, vehicles, and sometimes characteristics such as the colour of the clothing or of the car.
There is a trick that saves a lot of time and does not depend on the software: search first on the camera where there is a bottleneck —the door, the turnstile, the corridor everybody has to go down— to fix the exact time, and then go to the other cameras with that time. Searching straight away on the camera where it happened, which is usually an open area, multiplies the work.

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.
