The three zones that matter on an industrial site
Industrial risk is geographic. It concentrates at the boundary, the gate and the point where material changes hands.
The perimeter, after hours
A long compound wall cannot be patrolled continuously and does not need to be. A boundary rule on the cameras already facing the fence turns the whole length into something that reports a crossing in seconds, with a snapshot, during the hours you specify.
The gate
Everything of value enters and leaves through it, and in most plants the record of that is a notebook. Vehicle and plate logging turns gate movement into a searchable record, and shift-change attendance stops the queue at the biometric machine.
Dispatch and loading
The highest-value, lowest-watched area on most sites. Loading activity outside scheduled hours, or a vehicle at a bay when no dispatch is booked, is a rule worth having.
The yard in between
Scrap piles, finished-goods staging and parked trailers are where things sit unattended longest. Loitering rules catch the pattern that matters: someone present in a zone far longer than a legitimate task requires.
