Construction Sites Are Prime Targets—Here’s How to Lock Them Down   

Construction sites are busy by day—and vulnerable by night. With thousands of dollars in tools, heavy equipment, copper wiring, and materials left on-site, jobsites are a magnet for theft, vandalism, and trespassing. 

The problem? Traditional security doesn’t cut it. Static cameras miss key angles. Guard patrols are expensive. And a chain-link fence won’t stop a determined thief. 

That’s where Mobile Security Towers (MSTs) from Guardian Alarm come in—giving you the 24/7 eyes, alerts, and deterrents you need to protect your people and your project. 

• $1 billion+ in estimated annual losses from jobsite theft in the U.S. ([National Equipment Register]) 

• More than 70% of construction thefts happen after hours 

• Less than 25% of stolen equipment is ever recovered 

• Sites without surveillance are 3x more likely to be targeted 

• A single theft can delay a project by days or even weeks 

Bottom line: if you’re not securing your jobsite, you’re risking your timeline, budget, and reputation. 

Guardian Alarm’s Mobile Security Towers (MSTs) are rugged, rapidly deployable surveillance units built specifically for outdoor construction environments. Each unit includes: 

• 360° HD cameras with pan/tilt/zoom 

• Motion-triggered video alerts 

• Bright LED floodlights 

• Two-way audio to warn intruders 

• Solar or generator power options 

• Real-time monitoring by our UL-certified security team 

Best part? No trenching. No wiring. No permanent installation. We tow it in, set it up, and you’re protected—fast. 

A Mobile Security Tower is impossible to miss. 

Its tall profile, flashing lights, and visibly mounted cameras send a clear message: This site is protected. 

Studies show that visible security like this can reduce crime by up to 70%. Add in live two-way audio—where Guardian Alarm’s operators can issue real-time warnings—and most trespassers don’t even try to test it. 

It’s not just surveillance—it’s prevention. 

Unlike static cameras that only cover a fixed view, Guardian Alarm’s MSTs offer 360° panoramic coverage. 

That means: 

• Monitoring entry points, staging areas, trailers, and high-value zones simultaneously 

• Zooming in on suspicious activity with HD clarity 

• No blind spots—just total awareness 

And with advanced motion detection, you’re only alerted when it matters. 

When the system detects movement, our UL-Certified monitoring center gets to work: 

• Assess: Our team verifies whether it’s a threat (not a raccoon or fluttering tarp) 

• Respond: We issue live voice-down warnings to scare off intruders 

• Alert: We contact you and dispatch local authorities if needed 

All within seconds. You don’t just get footage. You get intervention. 

Hiring an overnight guard might seem like the safe choice—but at $25 to $50/hour, those costs add up fast. And even the best guards can’t be everywhere at once. 

Guardian Alarm’s MSTs provide 24/7 surveillance for a fraction of the cost, without fatigue, distraction, or time off. 

That savings compounds when you consider: 

• Fewer theft-related project delays 

• No insurance claims 

• No reordering or re-renting stolen gear 

Our MSTs are made to thrive in tough construction conditions: 

• Weatherproof for rain, snow, heat, or high winds 

• Tamper-resistant and locked to prevent interference 

• Fully mobile, with rapid deployment and relocation as your project moves 

From Downtown Detroit to the edges of Columbus, these towers perform—no matter the terrain. 

Whether you’re building a retail center, highway expansion, or single-family development—Guardian Alarm’s MSTs give you peace of mind, and real results.
