VDS vs. security guards.
What changes when a monitored mobile surveillance unit carries the coverage a guard rotation used to — and where a human on site is still the right call.
A monitored mobile surveillance unit covers an entire site perimeter 24/7 for one flat rate, while guards cover one post per person per shift at hourly rates. Most VDS customers cut traditional security spend by 70–90% on perimeter and after-hours coverage — and reallocate guards to interior and interaction roles where human judgment matters.
Side by side, factor by factor.
| Factor | VDS Monitored Surveillance | Manned Guards |
|---|---|---|
| Coverage | Full perimeter, 360°, 24/7 — every camera watches simultaneously | One post or patrol route per guard per shift |
| Cost structure | One flat rate — hardware, AI, monitoring, and maintenance bundled | Hourly wages × shifts × sites, plus overtime, turnover, and scheduling overhead |
| Deployment speed | Trailer live in under 20 minutes; most sites covered within a week | Contract, vetting, and scheduling — typically weeks to staff reliably |
| Consistency | Never sleeps, never calls out, no shift-change gaps | Quality varies by individual, shift, and staffing conditions |
| Evidence | Recorded 4K video, AI-tagged events, court-ready audit logs | Written incident reports; eyewitness accounts |
| Response | SOC operator verifies, talks down via speakers, dispatches PD with live video | On-scene presence — valuable, but one person facing unknown risk |
| Scalability | Add units per site; monitoring scales in the SOC | Linear — every site and shift needs another person |

Common questions.
Is mobile surveillance cheaper than security guards?
For perimeter and after-hours coverage, most VDS customers cut their traditional security spend by 70–90% — a 3–10× reduction — because one monitored trailer covers what would otherwise take multiple guard shifts. Your actual delta depends on local guard rates, shift count, and site size; the ROI calculator models it from your own spend.
Do cameras really deter intruders the way a guard does?
A monitored VDS unit is an active deterrent, not a passive recorder: intruders trigger AI detection, a SOC operator challenges them by live voice through 100dB speakers with strobes, and police are dispatched with live video when needed. Most intrusions at monitored sites resolve before escalation.
When do security guards still make sense?
Guards excel at interior posts, access control with human judgment, customer or employee interaction, and situations requiring physical presence. Many VDS customers keep guards for those roles and let monitored surveillance carry perimeter and after-hours coverage — reallocating people to where a person actually adds value.
Can VDS work alongside an existing guard contract?
Yes. A common model is guards during business hours with VDS covering nights, weekends, and the perimeter. The SOC can also route verified alerts to your on-site guard team instead of (or in addition to) police dispatch.
