The Challenge
A leading Naperville-area general contractor was managing an 18-month residential development consisting of 48 townhome units across a 12-acre site. The project included over $150,000 in copper wire and plumbing materials, installed in phases as buildings progressed from rough-in through finish.
Before engaging Complete Security Rental, the contractor had already experienced copper theft on two previous projects in the western suburbs. Those incidents resulted in:
- $45,000 in stolen copper wire and plumbing across both projects
- $28,000 in collateral damage (torn drywall, damaged conduit, rework labor)
- 3 weeks of combined project delays
- A 15% increase in their Builder's Risk insurance premium at renewal
The site's layout made security particularly challenging. With buildings spread across 12 acres and construction happening in multiple phases simultaneously, there was no single vantage point that could cover the entire development. The site bordered a public road on two sides, providing easy vehicle access for potential thieves.
The Solution
Complete Security Rental deployed 2 CCTV trailers equipped with advanced jobsite cameras, configured for maximum copper theft prevention:
Deployment Details
- Unit 1: Positioned at the main vehicle entry point facing the material storage area and first phase of construction
- Unit 2: Positioned at the secondary road-facing perimeter covering the active rough-in phase buildings
- Camera height: 30 feet, providing clear sightlines over the entire development
- Monitoring: 24/7 virtual guard service with professional monitoring and audio deterrent capability
- Repositioning: Trailers were relocated 3 times during the project as construction phases progressed across the site
Timeline
- Week 1: Site assessment and trailer placement planning
- Week 1 (Day 3): Both trailers deployed and operational - total setup time under 45 minutes per unit
- Month 6: First repositioning to cover Phase 2 buildings entering rough-in
- Month 11: Second repositioning as Phase 3 began
- Month 15: Third repositioning for final phase coverage
- Month 18: Project complete, trailers removed
Results
Over the 18-month deployment, the surveillance system produced measurable, documented results:
Zero Successful Thefts
Not a single theft was completed on the site during the entire 18-month project. This stands in sharp contrast to the contractor's previous two projects, where multiple theft incidents occurred.
Four Attempted Thefts Deterred
The monitoring center detected and deterred four separate intrusion attempts:
- Attempt 1 (Month 3, Saturday 2:14 AM): Two individuals cut the perimeter fence near the material storage area. Motion detection triggered, monitoring operator issued audio warning. Individuals fled immediately. Footage provided to Naperville PD.
- Attempt 2 (Month 7, Sunday 11:45 PM): A pickup truck entered through an unsecured construction access point. Strobe lights and audio warning activated. Vehicle reversed out within 30 seconds. License plate captured by LPR camera.
- Attempt 3 (Month 10, Holiday weekend, Friday 1:30 AM): Three individuals approached the Phase 2 buildings on foot from the public road. Audio warning activated before they reached the building. All three left the area. Police notified with video evidence.
- Attempt 4 (Month 14, Wednesday 3:20 AM): Single individual detected climbing the perimeter fence. Audio warning issued. Individual retreated. Monitoring center alerted police; patrol car arrived within 8 minutes.
Financial Results
ROI Summary
- Total rental cost (18 months, 2 units): $66,000 ($2,750 x 2 units x 12 months at 10% discount = $59,400, plus 6 months x 2 units at standard rate = $33,000, blended total approximately $66,000)
- Estimated prevented losses: $150,000+ in copper and materials
- Avoided collateral damage and rework: $30,000-$60,000 (based on prior project experience)
- Avoided project delays: 2-4 weeks saved (estimated value $40,000-$80,000)
- Insurance premium reduction: 12% reduction on Builder's Risk policy, saving approximately $8,500 over the project lifecycle
- Net benefit: $162,500-$222,500 in prevented losses and savings versus $66,000 investment
Client Perspective
"After getting hit on two previous projects, we weren't going to take any chances with this one. The surveillance trailers paid for themselves before the first phase was even complete. When you see four attempted break-ins get shut down in real time - with audio warnings that send people running - you understand the value immediately. We've now made mobile surveillance standard on every project over $5 million."

Key Takeaways
- Prevention beats recovery: With only ~20% of stolen construction equipment ever recovered, preventing theft is overwhelmingly more cost-effective than trying to recover losses
- Audio deterrence works: All four intrusion attempts were stopped by audio warnings before any theft occurred - no police chase, no confrontation, no loss
- Insurance benefits compound: The 12% premium reduction continues to save money on future projects, not just the one with surveillance
- Repositioning is essential: As construction phases progress, jobsite camera positions must adapt. Mobile CCTV trailers make this simple - repositioning takes 30 minutes
- Documentation matters: Video evidence from the four deterred attempts was provided to the contractor's insurance carrier, supporting their premium reduction and demonstrating proactive risk management
