Ask a warehouse manager what the security system is and the answer is usually a number of cameras. That is a recording, not protection. Cameras tell you what happened after the stock has gone. Protecting an industrial unit means deciding what has to be stopped, what has to be noticed and who has to be told, and then fitting equipment to those answers.
Start with where the losses actually happen
In a typical industrial unit, the risks cluster in a handful of places: the roller door and loading dock, the side and fire exits, the yard and fence line, the office where keys and paperwork sit, and the racking that holds the valuable stock. Break-ins are only part of the picture. After-hours access by people who should not have it, and goods that nobody can account for, are problems a system should help with too.
A walk of the site with those points marked is more useful than a quote that opens with a camera count.
Think in layers, not devices
The strongest warehouse systems work as three layers that cover for each other: something that deters and delays at the boundary, something that detects once the building shell is breached, and something that verifies and records what happened. A weakness in one layer is caught by the next.
The perimeter and the yard
Lighting, fencing and boundary cameras work together here. Cameras at the gate and along the fence line are about seeing what approaches, so lens choice, mounting height and night-time lighting matter far more than the number of units. Our security camera installations start from what each camera must be able to identify, not from how much wall there is to cover.
The building shell
Alarm sensors on roller doors, personnel doors and the internal spaces an intruder must cross turn a quiet break-in into a notified event. Whether the alarm is monitored matters as much as where the sensors go, because an alarm that only makes noise in an empty unit protects very little.
Inside: zones and who can enter them
Access control lets a warehouse treat areas differently. An access control system can limit who enters the stock room, the office and the dock, and it keeps a record of who used which door, which beats a ring of keys nobody can account for. Exit doors are the exception to lock-everything thinking: they must remain openable in an emergency, so lock hardware is chosen to release safely, and a building certifier should confirm the arrangement.
Loading docks and roller doors deserve their own plan
The dock is where goods legitimately leave and where they quietly leave too. Cameras that cover the door, the apron and the vehicle, an alarm input on the door so after-hours opening is flagged, and a clear delivery process do more together than any one of them alone. Camera positions should capture faces and number plates rather than the top of a forklift, and height, angle and light all affect that.
Recording you can actually use
Footage only helps if it is there and you can find it. Retention should match how quickly problems surface, and stock discrepancies often appear at the next stocktake rather than the next morning, so a week of storage may not be enough. Storage is worth sizing properly because resolution, frame rate and days kept all multiply together. Decide too who can view and export footage, and keep the recorder somewhere a thief walking through the office will not find it.
What WA law means for a warehouse
A warehouse has staff, and recording staff brings legal responsibilities. In Western Australia, the Surveillance Devices Act 1998 makes it an offence to install or use an optical surveillance device to record a private activity, with exceptions such as the consent of the people involved. In practice that means keeping cameras out of change rooms, toilets and similar spaces, telling staff what is recorded and why, and displaying signs. Cameras over ordinary working areas are routine, but the detail depends on your site, so confirm your position with a lawyer or industry guidance such as that published by the Chamber of Commerce and Industry WA. We cover the basics in our post on CCTV laws in WA.
Plan the cabling before the hardware
Large sheds punish poor cabling. Long runs to far corners, cameras on dock canopies and door controllers on remote doors all depend on cable that is installed, labelled and tested properly. It is the unglamorous work that decides whether the system is still reliable in three years. Wireless links have their place, but a building full of steel racking and sheet metal is an unforgiving place for them.
Industrial areas have different profiles
A big-box logistics shed, a workshop unit and a trade supplier face different risks. If your unit is in the south metro corridor, our page on security installations around Canning Vale Industrial is a useful starting point for the area.
Frequently asked questions
How many cameras does a typical warehouse need?
There is no standard number, because layout, aisle length, door count and lighting all change it. Cover the entries, the dock and the perimeter first, then the interior points a person must pass through, and only then add coverage for convenience.
Should a warehouse alarm be monitored?
Monitoring means someone is notified when the alarm triggers, rather than the siren simply sounding in an empty unit. For a site holding valuable stock or sitting some distance from other occupants, monitoring usually makes sense. The right choice depends on what is stored and how quickly you could respond yourself.
Can we use the cameras to check on staff performance?
Be careful. Systems are normally installed for security and safety, and using them to watch staff raises privacy and workplace policy questions. Tell staff what is recorded and why, keep cameras away from private areas, and get advice before using footage for anything beyond the stated purpose.
Will cameras work at night in an unlit yard?
Many cameras include infrared illumination that produces a black and white image in the dark, but its range is limited and detail drops with distance. Good lighting lifts image quality noticeably, so cameras and lighting are best planned together and tested after dark before the job is signed off.
Can we upgrade our old cameras without replacing everything?
Sometimes. If the existing cabling is in good condition and suits the new recorder, it can often be reused, which keeps cost and disruption down. It is worth testing the cabling and the mounting positions before deciding, since an old camera in the wrong position will not be fixed by a better recorder.
Walk the site with us before you buy anything
Before recommending equipment, we walk the building, the dock and the yard with you, mark where your stock is most exposed and tell you which layers matter most for your site, which is sometimes fewer devices than you expected.
