    Cost per Acre for Jobsite Monitoring in Houston — Sizing the Right Coverage

    4 min read·Updated July 21, 2026·By Guardtress Field Team
    TL;DR

    Effective monitored coverage on a Houston jobsite runs $180–$450 per acre per month depending on shape, ingress count, adjacent land use, and required camera density. A 5-acre linear site with two ingress points can be single-trailer covered; a 5-acre irregular site with four ingress points typically needs two trailers.

    The variables that drive per-acre cost

    Shape (linear vs irregular), ingress count, adjacent land use (industrial vs residential vs highway), fencing quality, on-site lighting, high-value asset concentration, and required LPR density all move the number.

    A rectangular 3-acre urban infill with one gate can hit $600 flat/month total. A 4-acre irregular vacant with four unfenced access points and a copper-worth MEP delivery may need $1,800/month.

    • Cost per acre (rectangular, single ingress): $180–$260
    • Cost per acre (irregular, multi-ingress): $350–$450
    • Cost per acre (vacant + unfenced): $400+
    • Fixed baseline per site: $1,800/month floor

    The sizing rules of thumb we use

    One monitored trailer with 4 PTZ cameras covers up to ~4 acres of contiguous, rectangular, lit perimeter with ≤2 ingress points.

    Beyond that, either add a second trailer or add pole-mounted cameras integrated to the trailer's NVR. Adding cameras is almost always cheaper than adding a second trailer.

    • ≤4 acres, rectangular, ≤2 ingress: 1 trailer
    • 4–8 acres or irregular: 1 trailer + pole cameras
    • 8 acres or ≥3 ingress: 2 trailers

    • High-value + linear (pipelines, road): 1 trailer per mile

    Where contractors over- and under-spend

    Under-spend: single trailer on 8+ acres because 'it's cheaper' — the blind zone becomes the loss zone. This pattern accounts for a disproportionate share of catastrophic loss in our incident database.

    Over-spend: two trailers on a 3-acre rectangular site because 'we want redundancy' — pole cameras integrated to a single trailer give you the same coverage at 40% of the cost.

    Quick FAQ

    Can Guardtress cover a 20-acre site?
    Yes — typically with 3–4 trailers or a trailer-plus-pole-camera hybrid. Cost stays in the $180–$450/acre band.
    What about linear sites like pipelines or roadwork?
    One trailer per mile of active work zone is the baseline, with pole cameras between.
    Do you cover multi-phase sites where zones change?
    Yes — trailers are relocatable inside 30 minutes; we adjust position as the site advances.
