A yard full of work vehicles, trailers and equipment is one of the easiest places for thieves to make money.
Victoria Police data for the year to June 2026 shows theft from motor vehicles accounted for 77,874 offences, more than 12% of all recorded crime in the state. It was the second-largest contributor to crime overall.
For trade businesses, transport operators and industrial sites, that risk sits in the yard every night. Utes loaded with tools, trailers left hitched, plant and machinery parked in the open. Here's how electronic security helps protect them.
Why yards and depots are targeted
Yards and depots combine everything an offender looks for.
- High-value equipment that is portable and easy to resell
- Trailers that can be hitched and towed away in minutes
- Work vehicles left loaded with tools overnight
- Large, open perimeters that are difficult to watch
- Predictable hours, with sites empty overnight and on weekends
The losses go well beyond the value of what is taken. Missing tools and vehicles mean cancelled jobs, idle staff and delays that flow through to clients.

1. Secure the perimeter first
The best time to detect an intruder is before they reach anything of value. Fencing and gates provide the physical barrier. Electronic perimeter detection adds early warning.
Outdoor detectors and beams, such as those from Takex, can be positioned along fence lines and yard boundaries. CCTV analytics can also detect a person crossing a defined line after hours. Either can trigger an alarm while an intruder is still at the fence.
2. CCTV that covers vehicle movement
A yard camera system should be designed around how vehicles and equipment move through the site.
- Entry and exit gates, where every vehicle must pass
- Parking bays for work vehicles and utes
- Trailer and plant storage areas
- Tool stores, workshops and fuel areas
- Laneways and rear boundaries
Night performance matters most. Many yard thefts happen in darkness, so cameras must be selected and positioned for low light, with suitable lighting where required.
3. Control the gates
A gate secured with a padlock and a shared key offers little control. Access-controlled gates allow staff and approved contractors to enter using their own credential, within set hours. Every entry is recorded.
When someone leaves the business, their access is removed instantly. There is no chasing up gate keys or changing padlocks.
4. Protect the keys
A vehicle is only as secure as its keys. Keys left in vehicles, on a hook in the office or in an unlocked drawer make a theft far easier.
The same pattern shows up at home. More than 11,000 vehicles were stolen from Victorian homes in the year to March 2026, often after keys were taken.
Keys should be stored in a locked cabinet, inside an alarmed area, with access limited to the people who need it.
5. Alarm the buildings and monitor the response
Workshops, sheds and tool stores should be alarmed, with detection covering doors, roller doors and roof access. Outdoor areas can be zoned separately, so the yard can be armed while staff are still in the office.
With 24/7 monitoring, an activation is acted on even when no one is on site. Linking cameras to the alarm allows the event to be verified quickly.
6. Layer site security with physical measures
Electronic security works best alongside good physical habits. Hitch locks, wheel clamps, vehicle trackers and removing tools from vehicles overnight all add further layers.
Each layer makes the site harder and slower to target.
What should a yard or depot security assessment consider?
Every yard is laid out differently. Worth checking for:
- Perimeter length, fencing condition and gate locations
- Where vehicles, trailers and plant are parked overnight
- Camera coverage at gates and storage areas
- Night performance and lighting
- Perimeter detection options for open boundaries
- Gate access for staff and contractors
- Key storage and control
- Alarm zoning and monitored response
