How much does a mobile surveillance trailer cost?

We reviewed the public materials of six providers in this category. Two publish figures you can quote; the rest do not. This is the complete picture as of September 2026, and every figure here comes from the company's own site or announcement rather than a third-party estimate.

A note on the four dashes: those providers do not publish pricing, and it would be irresponsible to fill the gaps with estimates. There is no shortage of specific-sounding figures online — during this review we traced widely-quoted rental ranges back to blog posts published by other vendors in the same category writing about each other, and a purchase estimate attributed to one provider back to a reseller page rather than the provider. Neither is a source you would want to defend a purchasing decision on.

If you find a figure for one of these companies, check whether the URL belongs to the company itself. If it does not, treat it as market gossip.

Total cost of ownership on a surveillance trailer is rarely dominated by the hardware line. Work through these with every vendor and ask for a three-year total, not a monthly figure.

Hardware or monthly rental

The headline number, and the only one most buyers compare. On a purchase, check whether cameras, gateways and speakers are included — at least one vendor publishes a trailer price that explicitly excludes all three. On a rental, check the minimum term.

Platform or software subscription

Per-unit or per-camera, usually annual. Ask whether it is required to operate the unit at all, or only for cloud features. A trailer that stops recording when a license lapses is a very different asset from one that keeps working locally.

Cellular data

Video is bandwidth-heavy and it is easy to under-budget. Ask for expected monthly data volume at your camera count and retention setting, whether overage is billed, and whether multi-carrier failover costs more than a single SIM.

Live monitoring

Priced per camera or per unit per month, and often the largest recurring line. Confirm what triggers an operator to look, what they are authorised to do, and whether dispatch or talk-down is billed per event.

AI and analytics licensing

The line most likely to surprise you. Some vendors tier analytics separately, and an entry-level unit may exclude the AI entirely — one provider's published entry unit states it excludes the vendor's agentic AI and advanced site-management features. Get the specific feature list in writing.

Deployment, installation and repositioning

Delivery, siting, mast raising, commissioning — and then every move afterwards. On a site where the work face shifts monthly, repositioning visits can quietly exceed the rental itself. Ask whether moves are included or billable.

Service and maintenance

Who attends when a unit goes offline, in what timeframe, and at what cost. Ask specifically what can be diagnosed and fixed remotely versus what needs a truck, because a site visit to power-cycle a gateway is pure waste.

Battery replacement

The long-term cost nobody quotes. Lithium banks degrade, and a trailer in year five may hold noticeably less charge than the spec sheet promises. Ask whether the battery is covered for the full warranty term or treated as a consumable, and what a replacement bank costs.

Replacement after theft, vandalism or damage

Surveillance equipment on an unsecured site is itself a target. On a rental, confirm whether replacement is included. On a purchase, this becomes an insurance question — and cloud recording matters here, because footage held off the unit survives the unit.

Contract term and exit

Minimum term, early-termination charge, per-site minimums, and what happens to your recorded footage when the relationship ends. Ask whether historical video is exportable and for how long it is retained after termination.

The mistake to avoid is comparing a fully-loaded monthly service price against a bare hardware price. A managed rental typically bundles the unit, platform, cellular, monitoring, service and replacement into one line. A purchase covers the equipment and leaves the rest to you.

To make them comparable, build both sides out over the same term:

Rental side

Monthly price × months of actual need per year × years, plus deployment and repositioning if billed separately, plus anything excluded from the monthly figure (AI tiers, data overage, event-based dispatch fees).

Purchase side

Hardware including cameras and gateways, plus annual platform licensing, plus cellular, plus monitoring if you want it, plus service, plus a battery replacement provision from around year four — then subtract residual value on equipment you still own at the end.

The variable that decides it

Utilisation. A unit deployed nine months a year and redeployed between projects amortises fast. A unit needed once for four months almost never does. Run the numbers at your real utilisation rather than a full-time assumption.

The crossover typically lands somewhere between 12 and 24 months on a single continuous site, and much sooner across a portfolio of projects. If you want rental economics without foreclosing ownership, some manufacturers offer dealer rental alongside purchase — Sharpvue runs a dealer rental program on both OpenEye and Alarm.com configurations, which lets a short project stay operational without a capital decision.

Two specifications affect long-run cost more than the purchase price, and both are under-disclosed across this category.

Runtime and recharge. An undersized power system produces brownouts in winter, lost footage, and service visits. Of the six providers reviewed, three publish battery capacity and only one publishes runtime and recharge time. Capacity alone cannot tell you runtime, because runtime is capacity divided by system load — see solar surveillance trailer runtime explained.

Platform portability.If the hardware only works on the vendor's platform, then changing software later means replacing the fleet. That is not a line on any quote, but it is the largest switching cost in this category — open vs. proprietary platforms covers the trade-off.

Sending the same brief to every vendor is the single most effective thing you can do to get comparable quotes. Include: number of sites and their coordinates or sun exposure, months of coverage needed per site per year, camera count and types required, whether you need LPR or thermal, retention period, whether you want live monitoring and to what escalation level, whether you have an existing VMS the units must feed, and whether NDAA documentation is required.

Then ask each for a three-year total against that brief. The spread you get back will tell you more about the market than any published price list would.
