Construction sites are prime targets for theft and vandalism. Equipment is left out, materials are piled high, and most sites are completely empty after work hours. With so many moving parts and people coming and going, security often takes a back seat - until something goes wrong.
That’s where mobile security trailers come in.
At Deetur, we’ve helped dozens of construction sites lock down their security without needing on-site guards. Our mobile surveillance trailers are built for this exact purpose: keeping your site safe, 24/7.
Here's how they work and why they’re quickly becoming the go-to solution for construction projects in Arizona and beyond.
Why Construction Sites Are Easy Targets
Construction zones are exposed. There are usually no fences, gates, or walls early in the build process. Expensive tools, copper wire, and heavy equipment are left out. And because the site is only active during the day, nights are wide open.
Some of the most common problems:
Tool and material theft
Vandalism (spray paint, broken windows)
Trespassing and liability risk
Delays caused by stolen gear
Replacing stolen equipment can cost thousands. Delays can cost even more.
What a Mobile Security Trailer Does
A mobile surveillance trailer is a self-contained, all-weather security unit. It typically includes:
Multiple high-definition cameras
Infrared/night vision
Loudspeakers and sirens
Floodlights or motion-activated lighting
Live 24/7 video monitoring
At Deetur, every trailer is actively watched by real people. If something suspicious happens - like someone entering the site after hours - we can respond immediately. That includes calling police, activating alarms, or contacting your team.
The goal isn’t just to catch criminals. It’s to stop them before they do any damage.
Real-World Use Case: A Commercial Property Owner Saves Thousands
One of our recent clients, a commercial property owner in south Phoenix, called after repeatedly having the copper stripped off their AC units. They lost about $30,000 in copper each year on holiday weekends.
We were called the Monday before Thanksgiving, and had a mobile security trailer deployed and set up on Wednesday 2 days later.
Over the holiday weekend there was no damage, and no criminal activity.
Client said it was the first Thanksgiving in 6 years they didn't have their units stripped over the long holiday weekend.
Fast Setup, Flexible Rental
We understand that construction timelines shift. That’s why our mobile trailer rentals start with a 3-month minimum, followed by month-to-month service. Need it longer? No problem - and we offer a 25% discount for 6+ month rentals.
Trailers are typically delivered and fully operational within 2 weeks of your request.
Key Benefits for Construction Sites
Visible deterrence – Trailers are tall, well-lit, and noticeable. That alone scares off most opportunists.
24/7 monitoring – Not just recording, but live human monitoring. Someone is always watching.
Fast response – If something happens, we take action immediately. No waiting to "review the tape."
Cost-effective – Less expensive than hiring guards. No breaks, no sick days, no shift changes.
Scalable – Need coverage for a larger site? We can deploy multiple trailers.
Don’t Wait for Something to Go Wrong
The truth is, most contractors don’t think about security until after a loss. That’s understandable - your focus is on timelines, materials, and labor.
But every theft or delay takes money out of your budget.
Don’t give criminals a free shot at your site. Don’t let your crew show up Monday morning to find the job stalled.
Protect your build site from day one.
