VDS vs. the
status quo.
Side-by-side comparison of VDS Mobile Surveillance Units against manned guard rotations and traditional fixed camera systems.
A monitored mobile surveillance unit covers a full site perimeter 24/7 and deploys in under 20 minutes, while guard rotations cover one post per shift and fixed cameras take weeks of trenching and permits. Most VDS customers cut traditional security spend substantially — guards are best reallocated to interior and interaction roles, not replaced outright. Deep dive: VDS vs. security guards.
Last reviewed: September 2026
Three approaches. Trade-offs on the table.
| Category | VDS MSU | Manned Guards | Fixed Cameras |
|---|---|---|---|
| Monthly cost per site | 5–10× less than guard rotations | Highest — three staffed shifts per post | High build-out, plus a separate monitoring contract |
| Deployment time | Same day | 1 – 2 weeks | 4 – 8 weeks |
| Relocatable | Yes — trailer-mounted, move in minutes | N/A | No — permanent install |
| Coverage area | 5–30 acres per unit, depending on sensor configuration | Limited to patrol route | Fixed field of view only |
| 24/7 monitoring | 24/7 SOC included | Requires staffing 3 shifts | Separate contract required |
| AI analytics | Cloud AI with up to 98% false-positive filtering | None | On-prem, limited models |
| License plate recognition | Built-in LPR option | Manual only | Separate hardware required |
| Live talk-down | Two-way audio from SOC | In person only | Rarely available |
| PD dispatch | SOC dispatches with live video | Guard calls 911 | End-user calls 911 |
| Power requirements | Solar-autonomous, no grid needed | N/A | Requires grid or PoE infrastructure |
| NDAA Section 889 compliance | NDAA 889-compliant — zero banned components | Not applicable | Varies by manufacturer |
| Mobile app access | iOS + Android with push alerts | None | Varies by VMS provider |
| Scalability | Add units on demand, fleet-wide dashboard | Linear headcount increase | New infrastructure per site |
| HR / liability risk | None — fully automated + SOC | High — workers comp, turnover, training | Low — but no active deterrence |
| Buy vs. lease | Buy, lease, rent, or month-to-month — purchase transfers title | Contract labor only | Capital purchase, plus install contract |
| Open platform (ONVIF) | ONVIF/RTSP — no mandatory software lock-in | N/A | Often locked to one VMS vendor |
| Named integrations | Immix, Milestone, Genetec, Bold, Stages, Lenel, Brivo, ServiceNow + REST API | None | Varies — often proprietary |
| Per-camera license | None — licensed per site | N/A | Common — per-camera VMS fees |
| Lead time | In-stock units ship out within 48 hours from Pikesville (freight varies by destination) | Staffing lead time varies | Weeks — trenching, permits, install crew |
| Custom spec | Cameras, sensors, mast, power quoted with a ship-out window | N/A | Custom builds add weeks to install |
| Dealer white-label | Hardware and platform white-label for dealers — no sell-around | N/A | Rare |
| Monitoring center | In-house U.S. SOC — optional, never outsourced or overseas | In person on site | Third-party central station, extra contract |
| Published specs | Full spec table + downloadable datasheet, ungated | N/A | Varies — often quote-gated |
When something else is the better fit.
Pick guards when…
You need physical interaction — access checks, escorting visitors, responding hands-on inside a building. Guards are not obsolete; they are mis-deployed on static perimeter posts. The strongest programs pair cameras on the perimeter with people — yours or your security partner's — handling verified incidents. Full breakdown.
Pick fixed cameras when…
The site is permanent, powered, and networked — a finished facility with conduit already in the walls. VDS installs those too (wall & pole mount), but a trailer earns its keep where power, network, or the site itself keeps moving.
Pick a managed fleet lease when…
You want zero ownership and one national vendor across hundreds of short-term sites, and you accept living in that vendor's platform. VDS's difference is the exit: buy or lease, ONVIF-open hardware, and integrations with the VMS and central-station tools you already run.
Every spec we compare on is published — see the MSU datasheet (PDF) and the machine-readable spec file. Savings figures are customer-reported; methodology on How We Measure.
Everyone else owns one layer.
VDS owns all five.
The mobile surveillance market is fragmented. Camera vendors hand you a box. Cloud-VMS platforms hand you software. VDS engineers, manufactures, monitors, and maintains every layer — under one US roof.
The math speaks.
