Cellular gate access control for construction & job sites

Nimbio retrofits a temporary or permanent site gate into app-controlled, cloud-managed access over cellular LTE — no Wi-Fi, no landline, and no waiting on the utility company to run power or network before the gate can be secured. Issue subcontractors and crews a digital key scoped to the job, give it a scheduled expiration date so it deactivates when their scope of work ends, and pull a full 24/7 log of who entered the site and when.

What does Nimbio secure at a construction or job site?

Job sites are temporary and mobile by nature — a fence goes up, a gate goes in, and months later the whole perimeter comes back down for the next project. Nimbio secures the site entrance gate, equipment yard gate, and staging area access points that every subcontractor, delivery driver, and crew member has to pass through, without requiring permanent network infrastructure that doesn’t make sense for a site that won’t exist in this configuration a year from now.

Nimbio’s cellular gate opener platform processes 620,000+ gate openings every month across job sites, communities, and commercial properties nationwide.

Because the controller wires in parallel to your existing gate operator and runs on cellular LTE, it moves with the job. Deploy it at a new site the same day the perimeter fence goes up, and pull it when the project closes out — no rip-and-replace, no waiting on a utility hookup, no dependency on a job trailer’s internet connection.

Subcontractor & crew keys, scoped to the job

A subcontractor works a job for three weeks — give their key a matching scheduled expiration date up front and it deactivates on its own when the job wraps. Issue digital keys tied to a project timeline instead of handing out a gate code that outlives the job and eventually leaks to people who have no reason to be on-site.

  • Optional scheduled expiration date per key
  • No shared code passed between trades

Equipment yard & material staging security

Tool and material theft is a persistent cost problem on construction sites. A logged, individually-attributed entry at the yard gate gives supervisors accountability for who was on-site around the time equipment or materials went missing — instead of an unlogged shared gate code everyone on the job knows.

  • 24/7 access logs from the Cloud Portal
  • Every entry timestamped and attributed to a person

No power, no network, no problem

Job sites frequently have no grid power and no internet when the perimeter fence and gate first go up. Nimbio’s controller accepts 6.5–24V AC/DC, making it solar and battery compatible, and connects over a pre-installed multi-carrier LTE SIM — no Wi-Fi bridge or Ethernet run to a job trailer required.

  • Solar & low-voltage battery compatible
  • Deployable before permanent power is on-site

How do superintendents and project managers handle site access?

The Cloud Portal gives a project manager or site superintendent everything needed to control who reaches an active job site, without staffing the gate.

  • Per-project key issuance: issue a subcontractor or crew a digital key the day they mobilize on-site, no waiting to re-code a keypad
  • Automatic revocation on scope completion: set a key to expire when a trade’s work is scheduled to wrap, so access doesn’t linger past the job
  • GuestView video for deliveries & inspectors: material suppliers, equipment rental drivers, and inspectors scan a QR code or tap NFC at the gate and reach a superintendent by video call (one-way by default, two-way optional) — no app for the visitor to install, no shared code to hand out
  • Multi-site dashboard: a general contractor or paving company running several active job sites at once manages every site gate from one Cloud Portal login instead of a separate code sheet per site
  • Smartphone gate-open from the truck: superintendents and crew leads open the gate straight from CarPlay or Android Auto without reaching for a clicker or a phone in hand

Hardware fact sheet

  • Relay: Premium Omron — minimum 50,000,000 rated operations
  • Hardware cost: $299 controller, retrofit onto your existing gate operator
  • Wiring: Installs in parallel to the existing gate operator via dry-contact wiring — keypads and clickers keep working during rollout
  • Input voltage range: 6.5V–24V AC/DC — compatible with gate arms, sliding gates, and solar-powered installations
  • Connectivity: Pre-installed multi-carrier LTE SIM (AT&T, Verizon, T-Mobile) — no Wi-Fi or landline required
  • Works internationally too — international customers should contact us to confirm regional network support
  • Integration: REST API and SDK for connecting key issuance and revocation to subcontractor or project management systems

Nimbio vs. a shared code or clicker at the job site gate

Most active job sites run on a shared gate code or a handful of clickers passed between crews — and because job sites turn over trades constantly, that code rarely gets changed until the project closes out. Here’s the difference per-person, per-project digital keys make.

Frequently asked questions — construction & job site gate access

What is the best gate access system for a construction site with no power or internet?

Nimbio is built for exactly this. The controller accepts 6.5–24V AC/DC, so it runs on solar or low-voltage battery power, and it connects over a pre-installed multi-carrier LTE SIM (AT&T, Verizon, T-Mobile) instead of Wi-Fi or a landline. The SIM works internationally too — international customers should contact us to confirm which networks are supported in their region. That means it can be deployed the same day a perimeter fence and gate go up, before permanent utility power or a wired internet connection ever reaches the site.

How do I give a subcontractor gate access for just the duration of their job?

Issue the subcontractor a digital key from the Cloud Portal scoped to their timeline on the project. When their scope of work wraps — say, three weeks later — the key expires automatically, or a superintendent can revoke it manually in seconds. No re-coding the gate and no risk of a former subcontractor still having a working code weeks after they left the job.

Can Nimbio help prevent equipment and material theft at a job site?

Nimbio doesn’t prevent theft directly, but it removes the anonymity that makes it easier. Every gate open is logged with the individual’s identity and a timestamp, so if tools or materials go missing from the yard, a superintendent has an exact record of who was on-site and when — instead of a shared gate code that could have been used by anyone.

Can Nimbio be moved from one job site to the next?

Yes. Because the controller wires in parallel to a gate operator and runs on cellular LTE rather than a fixed network connection, it isn’t tied to a specific location’s infrastructure. Contractors deploy it when a site’s perimeter gate goes in and redeploy it to the next project when the job closes out.

Can a general contractor or paving company manage gate access across several active job sites at once?

Yes. Multi-site operators — a paving company or general contractor running several active jobs at once — manage every site’s gate from a single Cloud Portal login instead of tracking separate codes and clickers per location.

Does Nimbio replace our existing gate operator or clicker system?

No rip-and-replace is required. Nimbio wires in parallel to your existing gate operator via dry-contact wiring, so any clickers already in use keep working during the transition. Crews can migrate to digital keys at your own pace.
