Theft from external intruders remains the number one security threat to warehouses
Unsecured perimeters, poor lighting, and patchy surveillance create opportunities. Most criminals don’t need to break in with tools; they walk straight through weak access points or exploit blind spots in the yard.
Thieves typically target warehouses for:
- Palletised stock stored outside the loading bay
- High-value items like electronics, tools, and seasonal goods
- Copper wiring and cabling from HVAC or solar infrastructure
Chris Clifton, Director at Safeguard Monitoring, explains:
“Too often we see warehouses focusing their CCTV inside the building, but by then it’s too late. Most thefts begin and end in the yard.”
As a result, evaluating the costs of CCTV monitoring for warehouses vs employing security guards is a highly recommended exercise.
Insider threats are difficult to detect
While rare, employee-related theft is a growing concern, especially in large 24/7 sites with temporary staff. Items can be concealed in clothing or stolen via ‘short-picking’, where only part of an order is loaded or fulfilled.
Telltale signs:
- Unusual stock discrepancies
- Regularly missing items in one product line
- Restricted areas left unlocked
Access control systems and specialist CCTV monitoring services for warehouses can help identify patterns without resorting to invasive supervision.
Poor perimeter security makes break-ins easy
Chain-link fences may look secure, but they’re no match for bolt cutters and ladders. And once inside, criminals often have minutes, or even hours, before anyone notices.
Perimeter vulnerabilities include:
- Gaps in fencing or gates left ajar
- Vehicles left parked near access points
- No detection for fence climbing or movement
Motion-activated cameras and virtual tripwires now allow real-time alerts when someone crosses a line — before they get to the building.
Weekend & overnight shifts leave sites exposed
Out-of-hours operations are often the weak link. Fewer staff, lower supervision, and dark areas create the perfect storm.
Common risks during these times:
- No one to raise the alarm in real-time
- Staff relying on traditional alarms without verification
- Intruders knowing shift handovers and blind spots
Live remote monitoring has become a popular solution, as it ensures there’s always a trained operator ready to assess footage and issue warnings if needed.
Fire & safety risks are often overlooked
While less dramatic than theft, fires can be catastrophic, especially in older warehouses or facilities storing flammable materials.
Risks include:
- Arson attacks (particularly in vacant or unsecured units)
- Overloaded electrics or faulty equipment
- Blocked emergency exits or expired fire extinguishers
Video monitoring can also play a role in early detection, particularly where thermal cameras or smart sensors are in use.

Vehicle-related crime is rising
HGVs are increasingly being targeted, both on-site and in transit. Criminals may try to:
- Steal fuel from lorries
- Tamper with seal tags
- Cut open curtain-sided trailers
Parking areas need the same level of surveillance as loading bays, and license plate recognition can help track who’s entering and leaving.
Cyber-physical attacks on smart systems
More warehouses are adopting smart sensors and IoT devices. But with more tech comes more risk.
Threats include:
- Network hacking of smart access control
- Remote disabling of alarm systems
- Tampering with camera feeds or data logs
Regular cyber audits and network segmentation are critical, and your physical and digital security must work in sync.
Summary: The major security threats facing warehouse operators
Security threats to warehouse operations aren’t limited to theft; they span safety, systems, and supply chain disruptions. The most successful operators don’t wait until there’s a break-in.
They invest in proactive, layered security strategies that combine physical deterrents, human oversight, and technology that adapts to modern risks.
