Warehouse Access Control for Internal & External Theft

Jun 5, 2025

How to Manage Access Control for Better Warehouse Security

Warehouses are the beating heart of a wide variety of businesses. Whether you are storing retail inventory, medical supplies, or high-value equipment, there’s probably a warehouse somewhere in the chain essential to your operation—and a prime target for theft. Between internal risks like employee misconduct and external threats like break-ins, warehouse security requires more than just locks and cameras. You need comprehensive warehouse access control that stays proactive, adaptable, and integrated.

A Growing Threat—Inside and Out

Warehouse theft is a growing problem across industries—and unfortunately, it’s not always committed by strangers. In fact, some studies have found internal theft (losses caused by employees) is more common than external theft in warehouse settings. These issues often begin with less-than-comprehensive access control.

At the same time, external threats are getting smarter as well. Modern criminals are finding new ways to exploit security blind spots, sneak in during shift changes, and target facilities with lax access control protocols. In either case, the warehouses without tight access policies and integrated surveillance become the likeliest targets.

What’s at Stake?

Failing to manage warehouse access control effectively can result in:

  • Theft of inventory, equipment, or tools
  • Operational disruptions due to missing goods or damaged facilities
  • Loss of trust among partners, clients, or insurance providers
  • Fines or legal action due to compliance violations
  • Increased liability for workplace safety incidents

So how do you protect your warehouse from both internal and external threats? It starts with smarter access control. Here’s what your team needs to know.

The Key Components of Effective Warehouse Access Control

Here at PEAK Alarm, we’ve worked with warehouses of all sizes across the Mountain West for more than half a century. We’ve had time to see what works—and what doesn’t. So, from your local experts, here are a handful of the best practices we recommend for effective warehouse access control.

1. Secure the Critical Zones First

Not all areas of your warehouse are equally sensitive. Identify your high-risk zones—such as inventory rooms, equipment cages, server areas, and shipping docks—and restrict access to authorized personnel only. These critical zones should never be accessible with a generic passcode or shared key.

Pro Tips:

  • Use electronic locks, card readers, or biometric scanners for secure areas
  • Consider additional authentication methods for select locations 
  • Ensure all entry/exit points are supported with real-time monitoring

2. Track Employee Movement

Warehouses often have dozens—if not hundreds—of employees, contractors, and temporary workers onsite. Knowing who’s coming and going (and when) is crucial to identifying potential threats before they escalate. Modern access control systems keep automated logs of entry events, which can be referenced at any time to verify who was on site at a specified time.

Pro Tips:

  • Implement ID badges or mobile credentials for each employee
  • Require badge scans at key checkpoints, not just main entrances
  • Review access logs regularly for unusual behavior, like off-hour access or repeated failed attempts

3. Increase and Specify Control 

Most thefts aren’t very complicated—especially the opportunistic ones. Getting away with theft is often as simple as walking through an unguarded door. Open docks, side entrances, and poorly lit back exits are frequent problem areas for warehouses. Avoiding this outcome requires both more comprehensive and more specific methods of control.

Pro Tips:

  • Secure all external doors—even docks—with electronic access points
  • Make access credentials time-sensitive, functional only during approved hours 
  • Use motion-sensor alerts for after-hours access attempts
  • Set different permissions for employees, vendors, and guests

For additional protection, PEAK recommends combining access control with intruder detection alarms and remote monitoring services, especially in isolated entry points.

4. Integrate With Video Surveillance

Access control is powerful—but when it’s paired with real-time surveillance, your security system becomes exponentially more effective. When an employee accesses a restricted area, for instance, video integration allows you to immediately verify that action with recorded footage. You’ll have a dependable source to verify with if you ever suspect credentials have been wrongfully shared or misused.

Pro Tips:

  • Cross-reference access logs with camera footage in seconds
  • Automatically trigger recording when access points are activated
  • Improve incident response with centralized monitoring dashboards

At PEAK Alarm, we make security simple by integrating multiple technologies through the same convenient interface. Our technicians can fully integrate access control and video surveillance systems to give warehouse managers complete visibility and control.

5. Schedule Regular Reviews and Maintenance

Perhaps the most important thing to remember is this: security is an active effort. Access control is not a set-it-and-forget-it solution, but a dynamic, living system that requires ongoing attention. Personnel changes, layout updates, or equipment wear can compromise your warehouse security if your system is not updated in turn. 

Pro Tips:

  • Make a point to audit access permissions every quarter
  • Revoke access immediately when an employee leaves
  • Test and update firmware on devices to ensure optimal function

PEAK Alarm’s access control solutions are a partnership—we stay on top of maintenance to keep your security technology working in peak condition. If and when something breaks, our team will be right there to fix it.
