The security measures inside most distribution centers are impressive and comprehensive. They rely upon multilayered strategies and best-in-class technology. Why? Well, they need to be. The value of goods within a distribution center can exceed $100 million. Even a smaller distribution facility will have inventory worth $10+ million. That incredible value makes it a rich target for thieves, and a “must-defend” for facility managers and other stakeholders.
The protective measures inside a distribution center include access control, video surveillance, and internal security systems. But what about outside the facility? At many facilities, the perimeter security practices are not as good as they can be — or should be.
That’s a major point of failure. Experts say the most important security measures are at a facility’s perimeter. The sooner a facility can identify, react, restrict, and prevent a dangerous act, the better. They want any incidents to occur as far away from the facility itself as possible. To achieve that mission, distribution centers need to make their perimeters a primary line of security. Achieving that goal may not be simple. Modern logistics facilities can span dozens, and at times hundreds, of acres. But don’t let size deter your ambitions.
Understanding a Distribution Center’s Perimeter Surveillance
A distribution center isn’t a single type of space; it consists of several task-specific areas, all necessary to achieve optimal logistical operations. These areas might be spread across a single large structure or across a large campus consisting of multiple buildings. No matter the property’s layout, the elements are usually the same; only the exact placements differ. Right now, let’s focus on the spaces near the perimeter.
Key Distribution Facility Perimeter Areas
- Trailer staging area
- Container yards
- Employee parking lots
- Truck queuing lanes
- Vehicle checkpoints
- Boundary fencing
The Three Needs for Perimeter Security
Creating effective perimeter security at a distribution center is built upon three pillars. These are the backbone for creating, maintaining, and activating threat deterrents and responses.
- Long-range single-mode fiber networks
- Power over Ethernet (PoE) perimeter infrastructure
- Automated gate access and surveillance systems
When the three pillars are unified into a single security solution, they provide a secure, scalable perimeter architecture that protects the facility’s valuable assets. The list of valuable assets includes inventory, vehicles, and, certainly, the most important asset, the people.
The three pillars identified here differ greatly from interior security measures.
Interior security relies on short copper runs, standard access-control hardware, and readily accessible power sources. When you extend your security layers beyond the walls, the tools and strategies change significantly. The biggest among them is the cabling that is used.
Fiber is the Backbone of Exterior Security
The single most crucial feature of a modern perimeter security system is the requirement for a fiber backbone. If you have, or expect to use copper, you’re doing it wrong.
The signal and power-carrying limits of copper cabling make it incapable of handling the demands and scale of perimeter security solutions. In fact, Ethernet standards limit copper runs to 328 feet, making it impractical for multi-acre sites. Does that mean your perimeter security won’t have any Ethernet at all? No, it will be essential for delivering power. We’ll explain that in just a bit.
The Advantages of Fiber
- Long-distance runs
- High bandwidth capacity
- Low signal loss
- Easily scalable
- Immunity from electromagnetic interference
- High-resolution video support
Fiber creates a network that can connect remote cameras, guard shacks, access control panels, gates, vehicle inspection areas, and more — no matter how spread out they are. Fiber can also handle higher data rates. That’s critical. Consider how much data traffic is created by a single 4K streaming security camera. Now multiply that by all the exterior cameras across a mult-acre property, and you start to understand the very real need for fiber. It is not a nice-to-have; fiber is a must-have platform.
Ring Topology: What It Is and Why It Matters
A ring topology can also be described as a network. It is what connects all the physical devices into a unified system. That includes cameras, motion sensors, alarms, and more. With a fiber ring, data travels sequentially from one device to the next until it reaches the central monitoring station or main control panel.
A properly designed ring topology includes multiple pathways for data to flow, enabling higher speeds and lower latency. Ring topology also supports less downtime, faster failover, improved resiliency, and easier IT maintenance. All of that is because ring topology isn’t dependent on a single route. If one becomes unavailable, traffic is redirected to another path.
PoE Requirements for Outdoor Security Systems
Let’s discuss the role Ethernet will play in perimeter surveillance and security.
The preferred method for powering exterior security devices is power over Ethernet (PoE). But aren’t we suggesting a fiber ring topology? Yes, but fiber is the backbone. The total solution is a hybrid approach that combines fiber and Ethernet.
Fiber on its own cannot carry power. It only carries light. So, fiber cable is used for data transmission across very long runs. Those runs will terminate at a network core remote enclosure. It will be inside those where a PoE switch is installed. The switch gets that data from the fiber line and then uses short Ethernet runs to provide power to any connected devices. This approach is referred to as a fiber-to-PoE switch solution.
Other Methods for Supplying PoE
- Fiber + Media Converter + PoE injector
- Composite fiber cable (fiber with copper conductors in the jacket)
When selecting a fiber-layered PoE solution, one of the most important tasks is determining the power budget. In other words, how much power is needed to access the ring topology? Underestimating power needs is a very common, and easily avoidable, mistake.
Calculating Power Needed for Each Device
- Peak power draw
- Startup loads
- Winter operating requirements
- Simultaneous device loads
- Switch power budgets
