Cargo and inventory theft costs U.S. businesses an estimated $15-30 billion a year, and distribution centers take more than their share of it. Cameras and locks matter, but neither one stops a theft in progress. A guard does. The value of a guard on site is that someone notices the trailer backed up to dock 7 with no scheduled pickup, and walks over before it pulls away.
This guide is for the facility or operations manager who has to budget and spec the coverage: the risks specific to a warehouse, what a guard actually does on shift, how to choose between a fixed post and a roving patrol, and what it costs.
Warehouse-specific risks
A warehouse doesn't face the same threats as a storefront or an office. The risk concentrates at the dock, in the aisles, and after the lights go off.
Cargo and inventory theft
High-value freight (electronics, pharmaceuticals, apparel) makes a distribution center a far bigger prize than a retail shelf. Theft crews have shifted toward distribution nodes for an obvious reason: one stolen pallet or full trailer is worth more than a week of shoplifting. The FBI puts cargo theft at $15-30 billion a year, concentrated heavily at distribution points.
The loading dock
The dock is the weakest point in almost every warehouse. Drivers, carriers, and third-party logistics staff cycle through all day, and during a busy receiving window a vehicle or person who doesn't belong blends right into the churn. That's how freight walks out on a truck that was never on the schedule.
After-hours intrusion
A facility that runs one shift sits empty for 16 hours a day. Anyone who has watched the building for a week knows exactly when it goes quiet, and a single-shift warehouse with no overnight coverage is, in practice, unguarded most of the day.
Internal theft
Employees account for an estimated 30-40% of warehouse shrink, and it is harder to catch than outside theft because the person doing it already knows the camera blind spots and the inventory process. Random patrols help mostly by breaking the predictability that internal theft depends on. A guard who walks a different route at a different time is hard to plan around.
Vendor and contractor access
Warehouses that run third-party fulfillment or handle multiple accounts host a steady stream of vendors, auditors, maintenance crews, and temps. Without a check-in process, nobody can say with confidence who is in the building right now. A guard at the entrance turns that from a guess into a log.
What a warehouse guard does on shift
A good warehouse guard is doing four jobs at once.
Access control. Checking driver IDs and manifests at the dock, logging visitors, issuing temporary badges, and turning away anyone who can't be identified.
Patrol. Walking or driving the perimeter and interior, checking that dock doors and pedestrian exits are locked, looking for propped doors, and clearing any vehicle parked on site after hours that shouldn't be.
Deterrence and response. The uniform does a lot of the work on its own; most opportunistic theft simply goes somewhere easier. When something does happen, the guard can detain a trespasser, call police, and keep the scene intact for the investigation.
Reporting. Logging every access event and incident through the shift. That record is what an insurer or an internal investigation actually runs on later, and a guard with no paper trail is a guard you can't back up after the fact.
Static post vs. mobile patrol
There are two coverage models, and most large sites end up using both.
Static post
One guard stationed at a fixed spot, usually the main vehicle gate or a dock. It works best when every truck has to be checked, when there's a single controlled entrance, and when vendors and drivers benefit from seeing the same face every day.
The tradeoff: a guard at the gate can't also cover 200,000 square feet of interior or a back fence line. A static post buys depth at one chokepoint and nothing anywhere else.
Mobile patrol
A guard moving through the site on a randomized schedule, on foot or in a marked vehicle, with GPS check-ins confirming each checkpoint was actually hit. It's the right fit for big multi-building campuses, outdoor yards, and overnight coverage where the real threat is someone coming over the fence. It's also what most insurers want to see documented.
The tradeoff: a roving guard can't process inbound trucks. A high-volume dock still needs its own static post.
The hybrid
Most warehouses over 50,000 square feet land on a mix: a static guard at the dock during receiving hours and a mobile patrol covering the full perimeter overnight. In practice that's two guards on the busy shift and one on patrol overnight.
Armed or unarmed?
Almost all warehouse coverage is unarmed, and that's usually the right call. Unless you're storing controlled pharmaceuticals, precious metals, or something with an extreme theft consequence, armed guards aren't standard, and plenty of landlords and insurers won't allow armed personnel on a commercial warehouse site anyway.
For the threats a normal warehouse faces (access control, internal theft, after-hours intrusion, dock management), an unarmed guard covers it.
Armed coverage is worth considering for pharmaceutical DCs handling scheduled narcotics, high-value electronics fulfillment, or any site that has already had a violent incident or a credible threat. It costs more, carries extra licensing and liability, and for most operations the math doesn't support it.
What warehouse security costs
Pricing varies by region, guard type, and hours. The rates below are national averages from the Calvis marketplace, which is what facilities actually pay rather than an opening bid.
| Guard Type | Typical Hourly Rate | Notes |
|---|---|---|
| Unarmed static guard | ~$29.60/hr | Standard dock post, visitor control |
| Unarmed mobile patrol (on foot) | ~$31.00/hr | Randomized interior/exterior rounds |
| Armed guard (unarmed-equivalent) | ~$42–$52/hr | Higher in coastal metros |
| Armed mobile patrol (vehicle included) | ~$59.68/hr | Vehicle, fuel, GPS tracking included |
Sample monthly budget: mid-size distribution center
This scenario assumes a 100,000 sq ft DC running two inbound shifts plus overnight coverage.
| Coverage Block | Hours/Week | Guard Type | Weekly Cost | Monthly Cost |
|---|---|---|---|---|
| Dock post (6am–6pm, M–F) | 60 hrs | Unarmed static | ~$1,776 | ~$7,700 |
| Overnight perimeter patrol (6pm–6am, 7 days) | 84 hrs | Unarmed mobile | ~$2,604 | ~$11,285 |
| Weekend day coverage (6am–6pm, Sat–Sun) | 24 hrs | Unarmed static | ~$710 | ~$3,080 |
| Total | 168 hrs/week | ~$5,090/week | ~$22,065/mo |
Actual costs depend on your metro area, shift length, number of guards per shift, and whether you need a vehicle included. High-cost states (CA, NY, WA) typically run 20–35% above the national average.

How to hire warehouse security guards
Hiring security through Calvis works differently from traditional security agencies. There is no annual contract, no minimum term, and no broker markup. You book by shift, and guards are dispatched from licensed agencies already vetted on the platform.
What to have ready before you book
- •Site dimensions and access points, how many entry gates, dock doors, and pedestrian exits need coverage.
- •Operating hours, do you need 24/7 coverage or only during inbound/outbound windows?
- •Special requirements, do guards need a forklift safety cert, or does your landlord require unarmed-only?
- •Post orders, a simple one-page document describing what you want guards to check, log, and report. Calvis can help you draft this.
Questions to ask any security provider
- •Are your guards licensed in this state, and can you provide proof of licensure?
- •How is GPS patrol verification documented, and can I access reports in real time?
- •What is your response protocol if a guard misses a checkpoint or fails to check in?
- •What does your post-incident reporting process look like?
- •Do you carry general liability insurance of at least $1M per occurrence?
What Calvis provides
Every booking through Calvis includes GPS-verified patrol confirmation, shift-by-shift incident reports, and the ability to book additional shifts or cancel with short notice. Guards arrive uniformed and briefed, you don't manage a staffing agency relationship.
