Warehouse Security in Ontario
A loaded trailer at the dock overnight, a fence line running along a rail spur, a gate that cycles all night for drivers. Guardian’s agents watch Ontario’s warehouses and distribution centers live, 24/7, warn intruders off before freight leaves the yard, and alert Ontario police with what they actually saw.

The Challenge
An Ontario Warehouse Break-In Costs More Than the Freight on the Trailer
Warehouse security in Ontario is a throughput problem before it is a building problem. A distribution operation is priced on orders leaving on schedule, and a single break-in — a trailer opened at the dock, pallets gone through a forced roll-up door — costs the freight plus the shift spent counting, the claims paperwork, and the customer whose order did not ship.
Cargo is the clearest example under state law. California Penal Code § 487h makes stealing cargo worth more than $950 — goods loaded into a trailer, railcar or cargo container, awaiting or in transit — grand theft. Ontario’s own crime data, reported through the California Department of Justice, carries no premise-type field, so there is no way to isolate a warehouse- or cargo-specific count from the citywide numbers — but the citywide numbers are real: Ontario Police reported 1,977 larceny-theft offenses in 2025, and only 297 of them — 15.0% — were cleared. A loaded trailer sitting in a yard overnight is logged the same way any other theft is. But the § 487h charge only exists once the load is already gone.
A gatehouse guard checks drivers in and cannot watch the far fence line. A drive-by patrol observes the yard for minutes. Recorded cameras explain a loss after the trailer is gone. Live video monitoring closes that gap: a trained agent watching the dock doors, the trailer yard and the fence line in real time, warning a person off through the site speakers before a seal is cut and, if they keep coming, alerting and coordinating with law enforcement with a verified description. For trailer yards and overflow lots without fixed infrastructure, the same coverage runs from rapid-deploy surveillance trailers.
U.S. and Canadian cargo-theft losses hit a record of roughly $725 million in 2025, and California accounted
for 38 percent of U.S. cargo-theft incidents — more than any other state.

What We Watch
What Warehouse Monitoring Covers in Ontario
Guardian’s warehouse monitoring puts trained human agents on your facility’s camera feeds in real time — dock doors, the trailer yard, gates, fence line and building entries — watching for theft, break-ins and trespass instead of leaving footage to be reviewed after the freight is gone.
AI flags activity on camera in under a second. A live agent verifies what triggered it and, if it is a real intrusion, speaks to the person through on-site speakers before a trailer door comes open or a seal is cut. The same agent alerts and coordinates with law enforcement and sends you a documented incident report.
The economics are why most operators switch: on-site guards run $25–30 per hour, while live video monitoring runs under $3 per hour — roughly 70% less for continuous coverage of the whole facility rather than one gatehouse.
Our Operations Center
Monitored Live for Ontario Warehouses From Our California Operations Center
A warehouse is at its most vulnerable in the hours it is designed to be empty — from the last truck out to the first shift in. Every Ontario facility Guardian protects is watched through those hours in real time by trained agents at our California operations center: a person seeing the dock apron and the trailer yard as it happens, not a recording pulled after a driver reports a cut seal. When AI flags activity in under a second, an agent verifies it on camera and delivers a live two-way warning through the site speakers before a trailer door comes open.
Ontario’s alarm rule works differently than a city with a verified-response ordinance. Under Ontario Municipal Code § 4-9.090(c)(2), a monitoring company must complete enhanced call confirmation — a second contact attempt to a different number — before Ontario police will act on a burglar-alarm request, and the department can refuse requests from a company that does not comply. Guardian’s agents already deliver more than that confirmation: a trained person who has watched the intrusion happen on camera, not a company working down a call list after a sensor trips. When Guardian alerts Ontario police, it comes with a live description and the exact location, and when an on-site presence is needed, Guardian sends its own licensed patrol.

Property Types
Built for The HUB and Ontario's Distribution Spine
Ontario’s newest large warehouse development is one project: The HUB Logistics Complex, a 215-acre site at Ontario International Airport, east of Haven Avenue between Jurupa Street and Airport Drive. Nine warehouses ranging from 200,000 to 930,000 square feet — 4.3 million square feet in total — sit at the intersection of the I-10, the SR-60 and the I-15, less than 45 miles from the ports of Los Angeles and Long Beach; four of the nine buildings were complete as of the developer’s mid-2026 update.
Ontario’s freight footprint continues down the Archibald, Milliken and Etiwanda corridors, past truck yards and equipment dealers on Holt Boulevard, and into the retail-adjacent industrial space near Ontario Mills at the I-10/I-15 interchange. Every one of these buildings shares the same overnight gap: loaded trailers at the dock, staged pallets behind a roll-up door, nobody on site until first shift.
Guardian covers all of it — fixed cameras and speakers for a leased HUB building with defined docks and entries, solar-powered surveillance trailers for a yard or overflow lot that needs coverage before a tenant even moves in. Guardian monitors warehouse and distribution property throughout Ontario and San Bernardino County.
Distribution Centers
How Remote Video Monitoring Protects an Ontario Distribution Center After the Last Truck Out
A leased HUB building doesn’t hand its risk off at the loading dock. Trailers sit staged along the apron, pallets wait behind a roll-up door, and drivers cycle through the gate well after the last shift clocks out — the same overnight gap Ontario’s Archibald, Milliken and Etiwanda corridor yards carry, just without a building wrapped around it. Guardian covers both: fixed cameras and speakers on a HUB dock apron and fence line once a building is occupied, a solar-powered trailer on an open corridor yard that has no fixed power yet.
When someone climbs the fence line after hours, the agent on the feed verifies it in real time, warns them off over the speaker before they reach a trailer, and gets Ontario police a verified description and location while the person is still on site. The property manager gets a time-stamped incident report the next morning, not a guess about what happened overnight.

Ontario Data
Ontario Police Logged 1,977 Theft Offenses in 2025 — 297 Were Cleared
The California Department of Justice’s 2025 data for Ontario, filtered to larceny-theft offenses, records 1,977 offenses citywide. Two hundred ninety-seven — 15.0% — were cleared; the rest remain open. Broken out by the value of the property taken, 1,247 offenses (63.1%) involved property valued over $200, 280 (14.2%) fell between $50 and $200, and 450 (22.8%) involved property under $50. The dataset carries no premise-type field, so there is no way to isolate how many of these offenses happened at a warehouse dock or in a trailer yard versus anywhere else in the city.
The takeaway is timing. With 85% of these offenses still open, the leverage sits in the minutes while someone is still on site: interrupt the intrusion as it happens, and when it cannot be stopped, hand Ontario police a verified, real-time description of the person and the vehicle instead of a case number filed the next morning.

FAQ
Warehouse Security in Ontario — FAQ
How does Guardian's agent respond when AI flags movement at an Ontario warehouse dock overnight?
AI flags the movement in under a second. A live agent pulls up the camera feed immediately, confirms whether it is a real intrusion, and delivers a two-way audio warning through the site speakers before anyone reaches a trailer or a dock door. If the person keeps coming, Guardian alerts Ontario police with a verified description and the exact location and, if an on-site presence is needed, sends its own licensed patrol. Every event closes with a time-stamped incident report you can hand to the property manager the next morning.
Does California's cargo-theft law cover a loaded trailer parked at an Ontario warehouse?
Yes. California Penal Code § 487h makes stealing cargo worth more than $950 grand theft, defining cargo as goods loaded into a trailer, railcar or cargo container, awaiting or in transit — exactly what sits in a distribution yard overnight. Ontario’s own crime data has no code that isolates cargo theft from general larceny, so no city-specific § 487h count exists — but the statute applies the same way it does statewide. An agent who sees someone at the trailer doors and alerts Ontario police while they are still on site changes the outcome regardless of which offense code the report ends up under.
Can Guardian cover a warehouse at The HUB Logistics Complex, or a trailer yard elsewhere along Ontario's distribution corridors?
Yes. The HUB Logistics Complex — nine warehouses totaling 4.3 million square feet going up near Ontario International Airport — gets fixed NDAA-compliant cameras and speakers on the dock and fence line once a building is occupied, or a solar-powered surveillance trailer covering a yard while it is still under lease-up. The same coverage extends down the Archibald, Milliken and Etiwanda corridors and the Holt Boulevard truck yards — send us your layout and gate schedule.
What does Ontario's 2025 theft data show about offense value, and what does that mean for coverage priority?
Of the 1,977 larceny-theft offenses Ontario police recorded in 2025, 1,247 — 63.1% — involved property valued over $200, the highest value tier the state file reports; 280 (14.2%) fell between $50 and $200, and 450 (22.8%) were under $50. The file has no $950 tier, so it cannot say how many would qualify as cargo grand theft under § 487h. Guardian’s site assessment prices coverage to what is actually staged on site.
