Construction security cameras range from about $150 for a single store-bought cellular camera to $1,450 or more per month for a live-monitored security trailer. Overnight and weekend security guard coverage runs about $9,300 a month in wages alone. What you pay depends on one question: do you want a recording, or do you want someone to stop the theft?
Most cost articles compare price tags. That's the wrong comparison. A $200 camera and a $1,450-a-month trailer aren't two versions of the same thing. One tells you what you lost. The other is built to keep you from losing it.
The four ways to put cameras on a job site
- Buy a cellular camera yourself: about $150 to $390 per camera at retail, plus a data plan. You're the one watching, if you see the alert.
- Buy and wire a fixed camera system: thousands up front, plus trenching or power drops if the site has no power. Usually no one is watching. It records.
- Hire a security guard: about $9,300 a month in wages for nights and weekends (see the math below). One person, who sees what's in front of them.
- Live-monitored surveillance trailer: as low as $1,450 a month with Autom. A trained monitoring team warns intruders and calls police.
Option 1: Buying your own cameras
A solar-powered 4G camera from a consumer brand costs roughly $150 to $390 depending on resolution and features. That's the cheapest way to get video on a site.
What you're really buying: a camera that sends you a notification. On a job site, that means wind, animals, and headlights will send alerts all night, and you're the one who has to wake up, check, and decide whether to call police. Most people stop checking after the first week.
It's a fine choice for a small, short project where you mostly want a record. It's not security.
Option 2: Buying a fixed camera system
Mounted cameras with a recorder work well on buildings with power and internet. On an active job site, they run into three problems:
- Power. Early in a project there may be no power to tap. Trenching for power adds cost and time.
- Moving. Job sites change. Cameras mounted for sitework are in the wrong place once vertical construction starts.
- No one watching. A recorder catches the theft. It doesn't stop it.
Option 3: Hiring a security guard
Guards put a real person on site, which matters on some projects. But the cost adds up fast.
The median wage for a U.S. security guard is $18.28 an hour (O*NET). A site that's empty from 5 p.m. to 7 a.m. on weekdays and all weekend is unattended about 118 hours a week, or about 510 hours a month.
- Nights and weekends: about 510 hours a month, or about $9,300 in wages.
- 24/7: about 730 hours a month, or about $13,300 in wages.
Those are wages only. Guard companies add their own margin, insurance, and overhead on top.
And one guard can only watch one part of a site at a time. On a big site, the back fence is just as open with a guard at the front gate.
Option 4: A live-monitored surveillance trailer
A mobile surveillance trailer combines several cameras, solar power, a cellular connection, strobes, and speakers in one unit. With Autom, a live monitoring team watches for people and vehicles after hours and responds in real time. (For how it works step by step, see what a mobile surveillance trailer is and how it works.)
Autom's live-monitored trailers start as low as $1,450 per month. That includes the trailer, cameras, power, cellular service, and live monitoring. There's no hardware to buy and no trenching.
What changes the price
- How long you need it. Longer commitments usually get a better monthly rate.
- How many trailers your site needs. A tight downtown lot may need one. A spread-out subdivision or a big commercial site may need two or more.
- What you're protecting. A site full of copper, HVAC units, and equipment has different needs than early grading.
The cost of doing nothing
The real comparison isn't trailer vs. camera. It's monitoring vs. a theft.
- The average stolen piece of heavy equipment was worth about $29,258 in the last national equipment theft report (National Equipment Register).
- Fewer than 7% of single-item jobsite thefts reported to police end with the property recovered (ASC research paper).
- Then there are the costs that don't show up on the police report: reordering, idle crews, and every trade behind you waiting.
At $1,450 a month, one stopped theft can pay for well over a year of monitoring.
Which option is right for you?
- Small, short, low-value site: a store-bought cellular camera.
- Power, a building, and a long timeline: a fixed system, ideally with monitoring added.
- You need a person checking people in at the gate during the day: a guard for daytime and a trailer for nights.
- Materials and equipment exposed at night and on weekends: a live-monitored surveillance trailer.

FAQs
How much does a construction security camera cost per month?
A store-bought camera has no monthly fee beyond a data plan, but nobody is watching it. Live-monitored security trailers from Autom start as low as $1,450 per month, including the hardware, power, cellular service, and live monitoring.
Is it cheaper to buy or rent construction security cameras?
Buying is cheaper up front if you only want recordings. Renting a monitored trailer costs more per month but includes the equipment, maintenance, moving it as your site changes, and a team that responds to intruders.
Are security cameras cheaper than a security guard?
Yes, by a wide margin. Guard wages alone for nights and weekends run about $9,300 a month at the median wage, before the guard company's markup. A live-monitored trailer starts as low as $1,450 per month.
Do construction cameras need power on site?
Not if they're solar powered. Autom's trailers run on solar with battery storage and connect over cellular.
