Warehouse Security in San Diego
A trailer backed up to the dock after the last shift leaves, a fence line running the length of a city block with nobody walking it, a gate that keeps cycling for drivers long after the office lights go dark. Guardian’s agents watch San Diego warehouses and distribution centers live, 24/7, warn intruders off before freight leaves the yard, and alert San Diego police with what they actually saw.

The Challenge
A San Diego Warehouse Break-In Costs More Than the Freight on the Trailer
Warehouse security in San Diego 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 harder case to see. Under California Penal Code § 487h, stealing cargo worth more than $950 — goods loaded into a trailer, railcar or cargo container, awaiting or in transit — is grand theft, but the charge only exists once the load is already gone. San Diego Police Department’s 2025 NIBRS data has no premise-type field, so there is no way to isolate a warehouse- or cargo-specific count from the citywide numbers — but the geography is telling: 4,295 motor-vehicle-theft offenses were logged citywide in 2025, and Otay Mesa, San Diego’s cross-border logistics and warehouse district next to the San Ysidro/Otay Mesa Port of Entry, recorded more of them than any other neighborhood in the city.
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 San Diego
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 San Diego 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 San Diego 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.
That live view is also what San Diego’s own alarm code expects, even though it is not named in it. Under San Diego Municipal Code § 33.3716, an alarm business must complete “enhanced call verification” — two contact attempts, in person, by phone or by another electronic means — before requesting a San Diego police response to any non-panic alarm signal, starting with the very first one; the code’s own definition does not list video or camera inspection as an accepted method. Guardian’s agent is already watching the camera live when AI flags activity, seeing the intrusion happen rather than waiting on an unanswered callback, and alerts San Diego police with a verified description while the person is still in the yard. A facility running an alarm system also needs a police-issued permit under § 33.3707(a), and an authorized responder must reach the premises within 30 minutes of a law-enforcement request under § 33.3709 — when an on-site presence is needed, Guardian sends its own licensed patrol.

Property Types
Built for the Docks, Trailer Yards and Border-Adjacent Corridors Across San Diego
San Diego’s warehouse and distribution footprint runs south to the border and north through the county’s business parks. Otay Mesa, next to the San Ysidro/Otay Mesa Port of Entry — the busiest land border crossing in the Western Hemisphere by vehicle volume — carries the city’s densest concentration of cross-border logistics and warehouse space, trailers staging for northbound and southbound freight around the clock. Kearny Mesa and Sorrento Valley, both established business and industrial park corridors, hold a mix of light-industrial and flex-warehouse buildings. Miramar and the wider South Bay add further distribution and logistics space closer to the airport and the harbor.
The shared problem is overnight: loaded trailers at the dock, staged pallets behind a roll-up door, nobody on site. Guardian covers all of it. Fixed cameras and speakers suit a building with defined docks and entries. Solar-powered surveillance trailers cover a trailer yard, an overflow lot, or a perimeter that needs coverage this week.
Guardian monitors warehouse and distribution property across the City of San Diego and San Diego County, from the border to North County.
Distribution Centers
How Remote Video Monitoring Protects a San Diego Distribution Center After the Last Truck Out
A distribution center’s real perimeter is bigger than its walls. Trailers sit staged in the yard, pallets wait behind roll-up doors, and drivers keep the gate cycling long after the office empties out. Guardian builds coverage around that reality — fixed cameras and speakers, or a solar-powered trailer where there is no power yet, watching the gate, the dock apron and the fence line as one continuous perimeter instead of a building with a yard attached to it.
When someone comes over the fence after hours, the yard is usually where it starts — a figure moving between trailers before ever reaching a door. The agent on the feed sees it happen, delivers a speaker warning before a trailer is opened, and alerts and coordinates with law enforcement with a verified description while the person is still on site. Every incident closes with a documented report the building owner can act on.

San Diego Data
SDPD Logged 4,295 Vehicle Thefts in San Diego in 2025 — Otay Mesa Was the #1 Neighborhood
San Diego Police Department’s 2025 NIBRS data records 4,295 motor-vehicle-theft offenses citywide, plus a further 3,786 offenses coded theft from a motor vehicle — property taken from inside or off a vehicle without taking the vehicle itself. Neither figure carries a premise-type field, so there is no way to isolate a warehouse- or trailer-yard-specific count from the citywide totals, but the geography is telling: Otay Mesa, San Diego’s cross-border logistics and warehouse district next to the San Ysidro/Otay Mesa Port of Entry, recorded more motor-vehicle thefts than any other neighborhood in the city — 534, plus another 90 in the adjoining Otay Mesa West, against runners-up Pacific Beach (210) and San Ysidro (189).
The takeaway is timing. With no way to know how many of these offenses started in a trailer yard rather than a driveway, 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 San Diego police a verified, real-time description of the person and the vehicle instead of a case filed after the fact.

FAQ
Warehouse Security in San Diego — FAQ
How many vehicle thefts did San Diego police log in 2025, and where?
4,295 motor-vehicle thefts and a further 3,786 thefts from a motor vehicle, citywide in 2025, per SDPD’s NIBRS data. Otay Mesa — San Diego’s cross-border logistics and warehouse district — recorded more vehicle thefts than any other neighborhood in the city, 534 of the 4,295. Guardian designs for that reality: an agent intercepts the intrusion live over the site speakers and documents every event in a time-stamped incident report — San Diego police get a verified account while the person is still on site, not a case filed after the fact.
Does California's cargo-theft law cover a loaded trailer parked at a San Diego 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. San Diego’s NIBRS data does not break any offense out by loading context, so there is no cargo-specific count to cite, but the statute applies statewide the moment the load is gone. An agent who sees someone at the trailer doors and alerts San Diego police while they are still on site changes the outcome.
Can Guardian cover a trailer yard in Otay Mesa, or a warehouse in Miramar or South Bay?
Yes. For a trailer yard or overflow lot in Otay Mesa, near the San Ysidro/Otay Mesa Port of Entry, Guardian deploys solar-powered surveillance trailers — no trenching, no waiting on fixed power. For a warehouse or distribution building in Miramar or the South Bay industrial belt with defined docks and entries, fixed cameras and speakers cover the dock apron, the gate and the fence line together. Send us your layout and gate schedule.
How does Guardian's agent respond when AI flags movement at a San Diego warehouse dock overnight?
AI flags activity on the camera feed in under a second. A live agent then verifies what triggered it — if it is a real intrusion, the agent delivers a two-way audio warning through the site speakers before a trailer door comes open or a seal is cut, and alerts and coordinates with San Diego police with a verified description and the exact location while the person is still on site. Every event is documented in a time-stamped incident report, whether or not anyone was there to see it happen.
