Why are the drives from a normal computer no good?
Because the job is different. A drive designed for surveillance is built to write without stopping, every day, with several streams coming in at once and with the vibration of other drives spinning alongside. A desktop one is designed to sit idle most of the day and work in bursts.
Put in a recorder it works, and it lasts far less time. They also behave differently when there is a read error: a desktop one can sit retrying for a long while, and the array controller reads that as the drive having died and throws it out. That alone is enough to set off a rebuild nobody asked for.
And there is a part that does not depend on the model: a drive that has spent years writing without stopping is at the end of its life even if it works. Replacing them on a schedule costs money; replacing them when they fail costs the recording from those days.

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.
