Between 08:00 and 17:00 the building is unarmed, full of people and open to deliveries.
Armed at night, off by day — An alarm covers the hours when nobody is there. The hours when strangers are on site are exactly the hours it is switched off.
It watches the perimeter — A door contact says the door opened. It cannot say the cabinet behind it was opened, or that a pallet left the yard.
The yard belongs to nobody — Containers, racks and parked machines sit outside camera coverage and beyond the reach of any cable.
The loss surfaces later — A missing tool is noticed the next morning, a missing pallet at the next count, and by then there is nothing left to react to.
Every object gets its own rule, and that rule is never switched off.
First movement — The moment a tool, a machine or a pallet is lifted, tilted or dragged, at a threshold you set so ordinary work stays quiet.
Opened or unbolted — Contacts on doors, windows, cabinets, panels and hatches, and on equipment fixed to its base.
Restricted zones — Areas nobody should enter are covered on their own schedule, by hour and by day of the week.
Indoors and outdoors — Wireless and battery powered, so a container in the yard is covered exactly like a cabinet in the workshop.
What it reports — That the object was touched, and precisely when. Where presence tags are also in use, you see who was in that zone at that minute.
Know the moment your property is touched — while there is still something to be done about it.
