Construction Site Security Cost Calculator: Guards vs. Remote Monitoring
Security guard coverage for an active LA construction site runs between $8,500 and $14,000 per month for a single overnight guard — before agency overhead, supervision fees, or insurance markups that routinely add 20–40% on top of the base billing rate. Remote video monitoring replaces that overnight coverage at a fraction of the cost. Most LA construction sites switching from guards to remote monitoring reduce their overnight security spend by 40% to 70%, depending on site size, shift length, and contract term.
ValleyGuard isn't a camera system that records what happens. It's a live monitoring service — AI-assisted detection triggers a review by a US-based Intervention Specialist who watches the footage in real time, issues a verbal challenge through on-site speakers, and contacts law enforcement directly if the threat continues. That response happens in seconds, not the 30+ minutes it takes for a standard burglar alarm to produce a police dispatch. Use the calculator below to estimate how much your specific guard setup could save with construction site remote monitoring.
✅ Live Intervention Specialist response — not just AI alerts
✅ Audio talk-down to stop intruders in real time
✅ Video-verified police dispatch
✅ Covers more area than guards at a fraction of the cost
Guard cost estimates are calculated at the billing rate entered and do not include agency overhead, supervision, insurance, or HR costs — your actual guard spend is likely higher. Monitoring cost savings shown are estimates based on typical deployments and do not represent a quote. Contact Valley Alarm for a site-specific monitoring plan and pricing.
Is Remote Monitoring Cheaper Than Security Guards for Construction Sites?
A licensed commercial security guard in Los Angeles currently bills between $22 and $45 per hour, according to the Bureau of Labor Statistics Occupational Employment data for California. Most general contractors working with mid-tier agencies report billing rates between $28 and $35 per hour for unarmed overnight coverage.
At $28/hour for a single guard covering 12 hours overnight, 7 days a week, that's roughly $10,200 per month — before the agency's overhead, supervision, and insurance markups are added. Projects requiring two guards per shift see that figure double immediately.
Remote video monitoring costs less than guards because a single Intervention Specialist can monitor multiple sites simultaneously using AI-assisted detection to filter real threats from false triggers — the same coverage model that requires one guard per site can be delivered by one operator managing several.
That's the structural cost difference. Valley Alarm quotes each site individually based on camera count, perimeter size, and coverage hours, but most construction deployments fall well below comparable guard costs for the same overnight window.
Project duration compounds the gap. A 3-month sprint pays close to month-to-month rates on both sides. A 9- or 12-month project is where the comparison becomes difficult to ignore — longer commitments unlock lower monitoring rates while guard costs stay flat or increase with agency fee adjustments.
| Factor | Security Guard | ValleyGuard Remote Monitoring |
|---|---|---|
| Monthly cost (1 unit, overnight) | $8,500–$14,000+ per month | Significantly lower — call for site-specific quote |
| Overhead (agency fees, insurance, supervision) | Add 20–40% on top of billing rate | Included in monitoring rate |
| Coverage area | One location at a time | Full perimeter via multiple cameras simultaneously |
| Response to threat | Physical presence — single point only | Live audio challenge + police dispatch in seconds |
| Police response priority | Standard alarm — 30+ min average | Video-verified — elevated priority dispatch |
| Deployment time | Varies by agency availability | 24–48 hours from signed agreement |
| Sick days / no-shows | Your problem to cover | Monitoring center staffed 24/7/365 |
| UL listing | N/A | Yes — UL-listed monitoring center |

What Drives Security Guard Costs on LA Construction Sites
Construction site security in Los Angeles runs overnight by default — from site close at roughly 4–6 PM through resumption of work the following morning. A 12-hour overnight shift, 7 days a week, is the standard coverage model for active job sites, and it's the single largest driver of guard cost. That's 84 hours of billable time per week, every week, for the duration of your project.
LA billing rates for licensed commercial security guards range from $22 to $45 per hour depending on the agency, the guard's license tier, and whether armed coverage is required. In California, all security guards must hold a valid license issued by the Bureau of Security and Investigative Services (BSIS), and higher-tier licenses command higher billing rates.
Two guards at $30/hour for 12 hours over 7 days equals roughly $22,000 per month before any overhead — and that's a conservative estimate for a mid-size commercial site.
Project duration is the other variable most GCs underestimate at the bid stage. A 3-month project pays month-to-month rates throughout. A 12-month project unlocks term-based pricing on the monitoring side that the guard side never offers — agency billing rates don't drop because you've been a client longer.
What ValleyGuard Covers — and What It Replaces
ValleyGuard is Valley Alarm's remote video monitoring service, operating out of a US-based monitoring center. AI-equipped cameras monitor your site continuously after hours. When a person or vehicle triggers detection, a live Intervention Specialist reviews the footage in real time — not an overseas call center, not an automated system. If the activity is a threat, the Specialist issues a verbal challenge via onsite speakers and contacts law enforcement directly if the subject doesn't leave.
Because ValleyGuard generates a video-verified alert rather than a standard burglar alarm signal, law enforcement treats it as a confirmed incident and elevates response priority.
That distinction matters on a construction site — response time is the difference between a theft attempt that gets interrupted and a completed loss. Standard commercial alarms in LA average 30 minutes or more for police response. Video-verified dispatch cuts that window significantly.
ValleyGuard is UL-listed and scales to fit your site — from a single access point to large perimeters with multiple staging areas and equipment yards. Valley Alarm quotes coverage individually based on camera count, site layout, and coverage requirements. Construction site overnight theft prevention is one of the most common ValleyGuard use cases, and deployments are typically operational within 24 to 48 hours of a signed agreement.
