The practical alternative to a security guard at a distribution center, trailer yard or cross-dock is live-monitored video: cameras covering the yard, the dock doors and the fence line, watched in real time by operators who can warn an intruder off through a loudspeaker and call the police with a description while the theft is still in progress. It costs a fraction of guard coverage, it never has a blind side, and it scales from one gate to a 40-acre yard without adding headcount.
Mobile Video Guard is a Bowie, Maryland security company that rents live-monitored mobile surveillance units to logistics yards, warehouses, distribution centers and construction sites in all 50 states. Our operators, many with law-enforcement backgrounds, watch sites live. This page covers how theft happens in logistics, why guards struggle to stop it, how monitored video works on a yard, and what to ask before you switch.
How logistics theft actually happens
Cargo theft in the United States has risen sharply. CargoNet recorded 3,625 cargo theft events in 2024, 27 percent more than the year before, with average losses above $200,000 per incident. Most of it is not a hijacking on the highway. It happens in yards and at docks:
- Loaded trailers parked overnight in a yard, broken into or driven away whole with a stolen or bobtail tractor.
- Fence-line pilfering: a cut in the chain link, a few pallets at a time over several nights.
- Dock-door theft during shift changes and after hours, often with inside knowledge of what is on which trailer.
- Fuel and catalytic converter theft from parked fleet vehicles.
- Fictitious pickup, where a fraudulent carrier collects a load. Cameras at the gate are the record that settles the claim.
Nearly all of it is at night or on weekends, and nearly all of it involves people checking first whether anyone is watching.
Why guards struggle on a yard
A guard is effective within sight of the guard. On a yard with 200 trailer positions, a guard at the gate house sees the gate. A guard on patrol sees a strip of the yard for a few minutes an hour and is predictable to anyone who watches for a night or two. Guard firms also carry the cost structure of a person: overnight rates, holiday rates, turnover, no-shows and the liability of a confrontation. For a single overnight post the bill is commonly well above $15,000 a month, and most yards need more than one post to cover the perimeter.
How live-monitored video covers a yard
- Coverage design. From your site plan we position mobile units or pole-mounted cameras to cover the gate, the trailer rows, the dock face and the fence line. Thermal and night-vision cameras see in total darkness.
- Detection. Analytics flag a person or vehicle in a zone and a time where there should be none, and filter out wildlife, weather and road traffic.
- Assessment and deterrence. An operator looks at the live feed within seconds. If it is a threat, they address the person by loudspeaker, describing what they are wearing and doing, and trigger strobes. Most leave at that point.
- Dispatch. If they stay, the operator calls the local police with a live description and remains on the feed to update responding officers.
- Record. The incident is clipped and shared with you and with police. Gate cameras also give you a timestamped record of every truck in and out for claims and disputes.
Units are solar or site-powered with cellular video, so a yard with no power or network at the fence line is covered the same as one with full infrastructure. They move as the yard layout changes.
What it costs compared with guards
A monitored yard is priced per site at a flat monthly fee that includes the equipment, the monitoring, moves and incident footage, with no long-term contract. For most yards that is a fraction of a single overnight guard post, and it covers the whole perimeter rather than one position. Clients who replace guard coverage with monitored video typically report savings of 60 percent or more. Where a person is still needed to process trucks at the gate during the night shift, the guard stays for that task and monitoring covers everything else.
What to ask before switching
- Is an operator watching live, or does the system only send alerts?
- Can they talk to an intruder through the unit and trigger strobes?
- Who calls the police, and do they stay on the line?
- Can the units run without site power and internet?
- What is included in the monthly price: data, monitoring, moves, footage, damage cover?
- How fast can a unit be on site, and how fast can it move when the yard changes?
- Is the provider a licensed security agency in your state?
Frequently asked questions
Can video monitoring replace security guards at a distribution center?
For perimeter, yard and dock coverage outside operating hours, yes. Tasks that need a person, such as checking in drivers at a 24-hour gate, keep a guard for those hours while monitoring covers the rest.
Does it work on a yard with no power?
Yes. Solar-powered mobile units with cellular video need nothing from the site and are the standard deployment for trailer yards and laydown areas.
What happens when someone cuts the fence?
The operator sees the person at the fence, addresses them by loudspeaker, activates strobes and, if they continue, calls the local police with a live description. The clip is sent to you the same night.
How quickly can a yard be covered?
Usually within 24 to 48 hours of the quote being accepted, anywhere in the United States.
Will my insurer accept monitored video instead of guards?
Most cargo and property policies accept professional live monitoring as a security measure, and some offer better terms for it. Check the wording; a few older contracts still name a guard.
